Izivakalisi ezibini zohlula ezi ntambo ngokusebenza. Umntu uthwala ubunzima bakhe kwaye akachukumisi nto yombane. Enye ithatha indawo yocingo lwakho lomhlaba kwaye ibe yinxalenye yenkqubo yomhlaba.
Ukuba uyachaza, thengisa kwakhona, okanye uvume i-aerial fiber usetyenziso lwamandla kunye neeprojekthi ze-telecom, Esi sikhokelo sikunika i-matrix yokukhetha eziguquguqukayo ezine endaweni yolunye uluhlu lweempawu. Ikwalungisa intelekelelo ebonisa phantse kuwo onke amanqaku akhuphisanayo - kwaye kwii-RFQ ezininzi esizifumanayo..
Yintoni Ngokwenene Eyahlula Ezi Cable
I-ADSS imele i-All-Dielectric Self-Supporting. I-All-dielectric ithetha ukuba akukho ntsimbi naphi na kwintambo - amandla avela kwiplastiki eqiniswe nge-fiberglass (FRP) ilungu eliphakathi kunye nomsonto we-aramid, usapho olunye lwefiber olusetyenziswa kwilaphu le-ballistic. Ukuzixhasa kuthetha ukuba ithwala ubunzima bayo phakathi kweenqaba ngaphandle kocingo lomthunywa olwahlukileyo.
OPGW imele i-Optical Ground Wire. Ingumqhubi wesinyithi odibeneyo kunye neyunithi ye-optical etywinwe ngaphakathi kwityhubhu yensimbi engenasici. Yenza umsebenzi osele uwenza ngocingo lwakho olungaphezulu komhlaba - ukuthintela umbane kwaye uphethe impazamo yangoku - kwaye ihambisa idatha ngexesha elinye..
Ngoku inxalenye etshintsha isigqibo sakho:
- I-ADSS yongezwa kumgca wakho. I-OPGW kukutshintshwa kwecandelo lomgca. Uxhoma i-ADSS kwiindawo ze-spare tower. Uthatha ucingo oludala lomhlaba ezantsi ukuze ufake i-OPGW.
- Kuphela i-OPGW ethwala impazamo yangoku. Inomlinganiselo wesekethe emfutshane. I-ADSS ayinayo umlinganiselo onjalo kwaye ayisoze, kuba ayenzi nto.
- I-ADSS inokufakwa rhoqo ngaphandle kokucima. I-OPGW phantse ayinakuze ikwazi. Ukutshintsha ucingo oluphantsi kuthetha ukuba isiphaluka siyehla.
UkuJonga iNyaniso yoMthengi: Xa umthengisi ecaphula zombini iinketho, umbuzo wokuqala ayiloxabiso. Yile nto: ingaba lo mgca sele unocingo olungaphezulu, kwaye umnini unenjongo yokuyichukumisa? Ukuba impendulo ithi “Ewe, kukho enye, kwaye hayi, asiyichukumisi,” I-OPGW iphumile etafileni phambi kokuba iindleko zingene kwincoko.
Ingqikelelo Phantse sonke isiKhokelo siyachaneka
I-ADSS ayiyomveliso enye.
Ijacket enye kunye neebhatyi ezimbini ze-ADSS zakhiwe ngokwahlukileyo, ukufikelela imigama eyahlukeneyo, kwaye uphile kwiimozulu ezahlukeneyo. Kwezinye izigqibo eziguquguqukayo, umsantsa phakathi kwabo ubanzi kunomsantsa phakathi kweADSS kunye ne-OPGW.
| Ibhatyi enye ADSS | Ibhatyi ephindwe kabini ye-ADSS | |
|---|---|---|
| Isilingi esebenzayo yespan | 300 m | Iminqamlezo yodidi oluyikhilomitha |
| Inkungu yetyuwa elunxwemeni, ikhephu elinzima, umkhenkce | Ayifanelekanga | Ifanelekile |
| Ubomi benkonzo eyongeziweyo kwezo mozulu | Isiseko | +10 ukuya 15 iminyaka |
| Isilingi yokubala ifayibha eqhelekileyo | 144 (288 ngesicelo) | 288 (576 ngesicelo) |
| Ixabiso lokuthenga elinxulumeneyo | Isiseko | +20% ukuya 25% kwinani lefibre elilinganayo |
Funda la mqolo wokuqala kwakhona. Inkcazo ebhalwe kwinqaku eliqhelekileyo - “I-ADSS ifikelela kwi 1,000 m” - ichanekile kulwakhiwo olunye kwaye ayilunganga ngenqaku lesithathu kwenye. Olu ngquzulwano silubona kwimibuzo yokwenyani: umthengi uthumela a 600 m span imfuneko ecaphula ixabiso lebhatyi enye abalifumene kwenye indawo.
Ngoko ukusuka apha ukuya phambili, esi sikhokelo siphatha ukhetho njengeendlela ezintathu, hayi indlela ezimbini.
Iyaguquguquka 1 -Iklasi yeVoltage kunye nento efunwa ngumgca
Iklasi ye-Voltage ibumba isigqibo esivela kuzo zombini iziphelo: imisela ukuba ngaba i-OPGW ifuna umlinganiselo othile wombane, kwaye imisela ukuba kunzima kangakanani okusingqongileyo kwibhatyi ye-ADSS.
Yintoni kuphela OPGW ezisa etafileni
Kuba i-OPGW ithatha indawo yocingo oluphantsi, ifumana ilifa lelo candelo imisebenzi yombane. Amanani amabini alawula ukucaciswa, kwaye akukho nto ilingana neADSS:
- Umthamo we-thermal wesiphaluka esifutshane (I²t) - angakanani amandla esiphoso intambo iwafunxa phambi kokuba umqhubi atshise ngokugqithisileyo kunye nemicu engaphakathi ekuphekeni.
- Ukuxhathisa kweDC - efuna ukuhlala kufuphi nocingo lomhlaba kwelinye icala lomgca, okanye aba babini babelana ngoku ngokungalinganiyo kwaye enye ibaleka ishushu.
Nanku ummeli we-48-fiber uqwalaselo esilwakhayo, ngoko unokubona ukuba la manani akhangeleka njani xa usebenza:
| Ipharamitha | Ixabiso |
|---|---|
| Ukuxhasa amacandelo ahlukeneyo | 64.51 mm² |
| Ilinganiswe Amandla Okuqina (RTS) | 71.37 kN |
| Umthamo we-thermal wesiphaluka esifutshane (I²t) | 28.80 kA²·s |
| Ixesha elifutshane langoku (1 s, 20 °C → 230 °C) | 5.37 kA |
| Ukuxhathisa kweDC | 1.161 Ω/km |
| Uxinzelelo lwemihla ngemihla (I-EDS) | 16–25% RTS |
| Ubushushu bokusebenza | −40 °C ukuya +80 °C |
| Idamitha yekhebula / Yamkela itekhnoloji yamva nje eyenziwe ngefiber | 11.10 mm / 429.64 kg/km |
Amacandelwana amakhulu entsimbi enqamlezileyo aphakamisa zombini umlinganiso wempazamo kunye namandla okuqina. Amacandelo amancinci axabisa ngaphantsi kwaye alayishe inqaba encinci. Uphononongo lwempazamo yomqhubi wegridi yakho lubeka umgangatho.
Iingongoma zokuThetha zoMhambisi: Xa umthengi oluncedo ebiza iklasi yombane kwaye ayeke apho, awukakwazi ukucaphula i-OPGW. Buza iimpazamo yangoku kunye nexesha lokucoca - ezi zimbini zivelisa i-I²t efunekayo - kwaye ubuze ukuba yintoniucingo ekhoyo emhlabeni DC ukumelana yi. Ukubuza oku kukujike ekubeni ngumthathi-maxabiso ube ngumlingani wobugcisa, kwaye kuthatha umyalezo omnye.
Yintoni eyenza amandla ombane kwiADSS
I-ADSS ayenzi nto, ke i-voltage ayigxininisi ngombane ngendlela egxininisa ngayo umqhubi. Uxinzelelo luphezu kwebhatyi.
Iikondaktara ezikufutshane, intsimi yombane iifom ejikeleze intambo. Ungcoliseko lomphezulu kunye nokufuma kugxininisa loo ntsimi ibe ngamabala amancinane owomileyo, kunye nokukhutshwa okuphindaphindiweyo kwe-micro-discharges i-polyethylene ngokuhamba kwexesha. Ukusilela kucotha. Ngokuqhelekileyo kubonakala kunyaka omnye ukuya kwemithathu emva kokugunyaziswa, okuthetha ukuba isigqibo sokuthenga kunye nesiphumo sahlulwe ixesha elininzi kangangokuba akukho mntu uzidibanisayo.
I-countermeasure yiAT (anti-tracking) ibhatyi ikhompawundi endaweni ye-PE eqhelekileyo. Sinikezela zombini, ngokutshintshisanayo, kwi 1.6 mm, 1.8 mm kwaye 2.0 mm ubukhulu bodonga, nge 1.8 mm ±0.1 mm njengomgangatho wethu.
Ingcebiso yePro yabathengi: Cela umthengisi wakho ukuba achaze, ngokubhaliweyo, i-compound yejacket kunye nobukhulu bodonga kwi-quotation - kungekhona nje “Intambo ye-ADSS.” Iingcaphulo ezimbini ezikhangelekayo 15% ngokwahlukeneyo kuhlala kukho umahluko we-PE-nxamnye ne-AT, kwaye umgca wexabiso eliphantsi unexabiso eliphantsi de ibe kukulungiswa okuqhutywa lukhukuliseko lokuqala.
Inqaku elikwitheyibhile zokukhetha: Iingcebiso zodidi lombane ojikelezayo kushishino zibonakalisa indlela eqhelekileyo, hayi umthetho wehlabathi. Iikhowudi zegridi zohlukile kulo lonke elaseLatin America, Afrika kunye noMbindi Mpuma, kunye neziko loyilo lweprojekthi okanye isebe lobunjineli obuluncedo libambe ilizwi lokugqibela. Phatha yonke itafile kwesi sikhokelo - kubandakanya neyethu - njengesiqalo saloo ncoko.
Iyaguquguquka 2 - Ubude beSpan, kunye nesizathu sokuba inani elinye lingasoze libe yimpendulo
I-span kulapho amanqaku egeneric enza owona monakalo mkhulu, kuba bacaphula ubuninzi obunye.
I-span figure ithetha into ethile ecaleni kwezinye iimeko ezintathu: ukulayishwa komoya, ukulayishwa komkhenkce, kunye ne-sag evunyelwe. Intambo efanayo ewela ngokukhululeka 300 m kwithafa elizolileyo aliyi kubamba umgama ofanayo ukuwela umqolo wentaba ovelileyo kunye nomkhenkce ojikelezayo.
YeADSS ngokukodwa, Isakhono se-span sivela kwi-aramid okanye i-polyester yarn strand count kunye nesakhiwo sejacket-hayi ukusuka kwi-fiber count kwaye kungekhona ukusuka kwi-diameter.. Yiyo loo nto i-span iyipharamitha yobunjineli oodola kuyo, kunokuba ipropathi esisigxina ujonge phezulu.
| Ibhendi yespan | Ibhatyi enye ADSS | Ibhatyi ephindwe kabini ye-ADSS | OPGW |
|---|---|---|---|
| Ngaphantsi 100 m | Ukhululekile | Icaciswe ngaphezulu | Iyasebenza, ukuba umgca ufuna ucingo oluphantsi kunjalo |
| 100-200 m | Intsimi eqhelekileyo | Ukhululekile | Iyasebenza |
| 200-300 m | Umda ophezulu | Ukhululekile | Iyasebenza |
| 300-1000 m | Ayifumaneki | Yenzelwe yona | Iyasebenza, RTS-ixhomekeke |
| Ngaphezulu 1000 m | Ayifumaneki | Ubunjineli obukhethekileyo | Iyasebenza, RTS-ixhomekeke |
Sakha ibhatyi enye ADSS ukuba 100 m, 150 m, 200 m kunye 300 m amanqaku ubude.300 m yisilingi, hayi ekujoliswe kuko - kwaye iyehla xa utyhala ifayibha count. Ulwakhiwo lwebhatyi yebhatyi ena288-fiber enye, njengokuba, ifuna ixesha elibanjwa ngokurhabaxa 100 m, kuba undoqo onzima utya uhlahlo lwabiwo-mali loxinzelelo.
Iingongoma zokuThetha zoMhambisi: Xa umthengi esithi “600 m ubude,” imibuzo emithathu elandelayo ilungisa isicatshulwa: Yintoni isantya somoya esiyiliweyo? Ngaba kukho ukulayishwa komkhenkce? Yiyiphi i-sag evumelekileyo xa kuwela? Ngaphandle kwezo, Nasiphi na isithembiso se-span yi- guesswork - kwaye ukuqagela yeyona nto ibuyiswayo.
Iyaguquguquka 3 -Ulwakhiwo olutsha okanye iRetrofit, kunye nokuba unokuPhumla na
Oku kuguquguquka kugqiba iiprojekthi ezininzi kunexabiso, kwaye licande libe nyulu.
Iintambo ezintsha zothumelo
Umgca omtsha udinga ucingo oluphantsi kungakhathaliseki. Inqaba iyayilwa kunjalo, ukulayishwa kubalwa kunjalo, kwaye abasebenzi bentambo bakwisiza kunjalo. Ukukhetha i-OPGW kweli nqanaba kuthetha ingokwandayo Ixabiso ngocingo olusemhlabeni olulula lithobekile - uthenga ifayibha, ayithengi inkqubo yokuhlohla eyahlukileyo.
This is the strongest argument for OPGW, and it has nothing to do with the cable being “better.”
Retrofitting a line already in service
Now the arithmetic inverts. Replacing an in-service ground wire with OPGW requires taking the circuit out of service — and the outage is rarely the cheap part.
Real-World Scenario: On a live network, an outage is not a scheduling detail. It goes through a dispatch approval queue, competes with maintenance windows already booked, and may require replacement generation or rerouted load for the duration. Project teams routinely find the outage window harder to secure than the cable is to manufacture. Fifteen working days for cable delivery means very little when the switching request sits in a three-month queue.
ADSS exists largely because of this problem. Kuba ayibambanga ntsimbi, inokufakwa kwiindawo ezisecaleni zenqaba ngaphandle kokuba yinxalenye yesixokelelwano sombane.
Kufakelo lwe-live-line ngokukodwa: ukwakhiwa kwe-dielectric yonke kwenza ukuba kwenzeke ngokomgaqo. Nokuba ivumelekile nayakho umgca uxhomekeke kwiklasi yombane, iinkqubo zokusebenza ezisebenzayo, iziqinisekiso zabasebenzi kunye nogunyaziso lomnini we-asethi. Nyanga “I-ADSS inokufakwa ngqo” njengombuzo wegunya lokhuseleko loncedo lwakho, hayi njengengcaciso onokuyicinga. Siyavuya ukubonelela ngedatha yentambo yeemfuno zakho zokhuseleko; asizukuxelela ukuba umsebenzi ukhuselekile kumgca esingawubonanga.
Iyaguquguquka 4 - Iindleko zizonke zoBunini, Hayi ixabiso ngemitha nganye
Uthelekiso lwexabiso ngemitha nganye phakathi kwe-ADSS kunye ne-OPGW luyalahlekisa, kuba aba babini abathengi into enye. Ixabiso le-OPGW libandakanya ucingo olusemhlabeni onokuthi uthenge ngokwahlukileyo. Ixabiso le-ADSS alibandakanyi ucingo oluphantsi kuba i-ADSS ayikho enye.
Iibhloko ezine zeendleko ziphantsi kothelekiso olunzima. Uninzi lothelekiso olupapashiweyo lugubungela eyokuqala kwaye lutsibe oluseleyo.
| Ibhloko yeendleko | I-ADSS (omnye) | I-ADSS (kabini) | OPGW |
|---|---|---|---|
| Izinto eziphathekayo | Elona lisezantsi - malunga ne-25-40% ngaphantsi kwebhatyi ephindwe kabini, umsantsa uyacutheka njengoko ubalo lwefayibha lunyuka | +20-25% ngaphezulu kokunye kwifayibha count elinganayo | Elona liphezulu ngemitha, kodwa ibandakanya umsebenzi wocingo oluphantsi |
| Ukufakela umsebenzi | Eyona ntambo ilula, akukho msebenzi womqhubi | Indlela efanayo, intambo enzima | Ukususwa kweengcingo eziphantsi kunye nentambo; ukuphatha okunzima |
| Iindleko zokucima | Kusoloko kuphetshwa | Kusoloko kuphetshwa | Idla ngokuthintelwa kwiretrofits - rhoqo eyona nto inkulu yomgca omnye |
| Tower iyalayisha | 91 kg/km kwi 48 Isiqhekeza ngasinye sahlula isiginali ukusuka kwifiber enye ukuya kuyo | 128 kg/km kwi 48 Isiqhekeza ngasinye sahlula isiginali ukusuka kwifiber enye ukuya kuyo | 429.64 kg/km kwi 48 Isiqhekeza ngasinye sahlula isiginali ukusuka kwifiber enye ukuya kuyo |
| Ukugcinwa kwexesha elide | Ukhukuliseko lwebhatyi kunye nokuguga kwe-UV zizinto zokubukela | +10-Iminyaka eyi-15 yongeza ubomi kwiimozulu ezinzima | I-Metallic corrosion kunye nengqibelelo ephantsi zizinto zokubukela |
Inombolo yokulayisha inqaba akukho mntu ucaphulayo
Jonga kumqolo wesine. Kwangaxeshanye 48 Isiqhekeza ngasinye sahlula isiginali ukusuka kwifiber enye ukuya kuyo, OPGW yethu inobunzima429.64 kg/km ngokuchasene91 kg/km yebhatyi enye ADSS - ngokurhabaxa 4.7 amaxesha anzima - kwaye malunga 3.4 amaxesha anzima kune-double-bhatyi ADSS kwi 128 kg/km.
Impembelelo yoRhwebo: Kumgca omtsha, inqaba yenzelwe loo mthwalo kwaye inani alingomcimbi. Kumgca omdala, ngumbuzo wesakhiwo ofika emva kwexesha kwaye ubiza imali - uvavanyo lokulayisha, kwaye ngamanye amaxesha ukuqinisa. Ukuqiniswa kweNqaba akubonakali kuyo nayiphi na isicatshulwa sentambo, yiyo kanye loo nto iphazamisa uhlahlo lwabiwo-mali lokubuyisela.
Apho ipremiyamu yebhatyi ephindwe kabini ihlawula kwakhona
Ukuhlawula i-20-25% ngaphezulu kwijacket yesibini ibonakala njengento elula yokusika ngexesha lobunjineli bexabiso. Kwinkungu yetyuwa elunxwemeni, ikhephu elinzima okanye iimeko zomkhenkce, kukunqunyulwa okungalunganga.
Ibhatyi enye ADSS yiayifanelekanga kwezo ndawo. Inkungu yetyuwa ikhawulezisa uhlaselo lwekhemikhali kwibhatyi; xa ibhatyi iphazamisekile, iaramid ngaphantsi ilahlekelwa lukhuseleko lwayo. Isikhundla sethu sithe ngqo: kwindawo enetyuwa eninzi okanye i-icing, sincoma ijacket ephindwe kabini kunokuthengisa ibhatyi enye etyebileyo njengendlela yokusebenza. Ukwakhiwa kweebhatyi ezimbini zongeza uqikelelo10 ukuya 15 iminyaka ubomi benkonzo kwezo meko, ecaleni kokumelana nokukhukuliseka okungcono kombane kunye nokuthintela amanzi anemigangatho emibini.
Siqinisekisa oku ngovavanyo lwesitshizi setyuwa lweyure ezingama-720 kunye nokuguga kwe-UV kuvavanywa kwi-GB/T 18899-2023. Buza nawuphi na umthengisi ukuba loluphi uvavanyo lokuguga abaluqhubayo, kwaye zingaphi iiyure.
Ukuyibeka Ndaweninye — IMatrix yokuKhetha okuZine
Umqolo ngamnye ongezantsi unengcebisoUphuculo olongezelelweyo kumgangatho wokuqala we-APON - kunye nokuwa kancinci kancinci kwi-ATM njengeprothokholi - kukhokelele ngokupheleleyo. imeko eyibhukuqayo. Umqathango wokubhukuqa yinxalenye ebalulekileyo, kuba iprojekthi yakho ekugqibeleni iya kubetha enye.
| Imeko | I-Voltage | Ispan | Yakha uhlobo | Yaya ngase | Yintoni ebhukuqayo |
|---|---|---|---|---|---|
| Intambo entsha yothumelo | HV / I-EHV | Nayiphi na | Plug-in/Module Type PLC Splitter evela China-Fibconet | OPGW | Uyilo lwenqaba sele lulungisiwe kwaye alukwazi ukufunxa umthwalo |
| Ukubuyisela kwakhona, ucingo lomhlaba lukwimeko entle | HV / I-EHV | ≤ 300 m | Ukubuyisela kwakhona | Ibhatyi enye ADSS | Unxweme, umkhenkce, okanye indawo enongcoliseko oluphezulu → ibhatyi ephindwe kabini |
| Ukubuyisela kwakhona, ukunqumla ixesha elide | Nayiphi na | > 300 m | Ukubuyisela kwakhona | Ibhatyi ephindwe kabini ye-ADSS | Ukucinywa kuyaphunyezwa kwaye uphuculo lwecingo olusezantsi luza kwenzeka → OPGW |

| Umgama omde umqolo | HV / I-EHV | Ixutyiwe | Plug-in/Module Type PLC Splitter evela China-Fibconet | OPGW | Indlela inqumla kumhlaba apho ukucima kungenakucwangciswa → ADSS |
| Nayiphi na iprojekthi, imozulu embi | Nayiphi na | Nayiphi na | Okanye | Ibhatyi ephindwe kabini ye-ADSS okanye i-OPGW | Neither — do not put single-jacket into salt fog or icing |
The variable this matrix cannot decide for you: fiber count
Almost no buying guide addresses fiber count, yet every purchase order requires the number.
Two principles apply. Ekuqaleni, build in headroom — utilities that specify only for today’s SCADA and protection traffic tend to return within a few years needing capacity for substation automation, video inspection or telecom backhaul, and a second cable pull costs far more than spare fibers ever did. Ngeenxa zonke 30% spare capacity is a common planning allowance.
Isibini, respect the trade-off. More fibers means a heavier, thicker cable, which reduces achievable span. Our single-jacket ADSS runs 4 ukuya 144 fibers as standard, nge 288 available on request when the span stays near 100 m. Double-jacket reaches 288 as standard and 576 ngesicelo. OPGW tops out at 96 Isiqhekeza ngasinye sahlula isiginali ukusuka kwifiber enye ukuya kuyo.
Ingcebiso yePro yabathengi: Gqiba ukubala kwefayibhangaphambili ugqibezela isikali sexesha, hayi emva. Ukubalwa kweFayibha kutshintsha ubunzima bentambo, Ubunzima bekhebula butshintsha uxinezeleko, kunye noxinzelelo lutshintsha i-span intambo inokubamba. Ukubuyisela umva loo myalelo yindlela iiprojekthi eziphela ngayo ziodolwa ngokutsha.
Imigibe yaseNdaweni Ebonakala emva kokuba iCable Sele Ijinga
Zombini iintlobo zekhebula zineepateni zokungaphumeleli ezibhalwe kakuhle. Ayikho ipateni eneneni malunga nentambo.
Kwicala leADSS
- Ukhukuliseko lwebhatyi kwikhompawundi engalunganga. I-PE esemgangathweni kwi-high-field okanye i-high-contamination position iyancipha. I-AT ikhompawundi ikhona ngenxa yesi sizathu. Uphawu luvela emva kweminyaka, kude nesigqibo sokuthenga.
- Ukungcangcazela kweAeolian. Isibane, intambo ye-dielectric yonke kwii-oscillates zomoya ezizinzileyo. Ngaphandle kwee-dampers, ukukhathala kugxile kwii-clamps.
- Ibhatyi enye kwimozulu engalunganga. Igutyungelwe ngasentla — le yimpazamo yokucacisa, hayi eyemveliso.
- Ufakelo lucingelwa ukuba luyatshintsheka. Abekho. Ijacket enye kunye neebhatyi ezimbini ze-ADSS zineemitha ezahlukeneyo zangaphandle, ngoko ke ukunqunyanyiswa kunye nesiphelo sokugqibela iiclamps ezinobungakanani bomnye aziyi kubamba ngokuchanekileyo enye. Uhlahlo lwabiwo-mali oluhambisa ixabiso lentambo phambili kodwa luphinde lusebenzise into yomgca wofakelo oludala luba mfutshane.
Kwicala le-OPGW - apho iintsilelo zidibana khona
Le yinxalenye phantse akukho uthelekiso igubungela, kwaye ifuna ingqalelo.
Uphando lwasemva kwemigangatho yofakelo olupapashiweyo lukhomba kwisigqibo esifanayo: OPGW iziphene zigxile kwiukuthoba kunye nokupheliswa kwe-splice, hayi ngexesha. Intambo phakathi kweenqaba ziziphatha kakuhle. Ukusilela kwenzeka kwiimitha ezimbalwa zokugqibela, apho intambo yehla kwisakhiwo kwaye ingena kwi-splice enclosure.
Iindlela ezintathu zokuyiqhuba, kwaye zontathu ziyi-physics kunolawulo lwasekhaya:
- Ilahleko yokukhutshwa kwe-insulating. Apho i-downlead yenzelwe ukuhlala icacile kwisakhiwo, izibophelelo zerabha ezigugayo kunye neebhanti ezibolayo ezingenakutyiwa zivumela intambo ukuba ikhukuliseke ukuze idibane. Ukhukuliseko olukhutshwayo luyalandela, kwaye imisonto iyaqhawuka.
- Uqhagamshelwano lwesinyithi olungafaniyo. Ibhanti yentsimbi engatyiwayo ngokuchasene nocingo lwe-aluminiyam imisela ukuthotywa kwegalvanic. Ibhendi iyasilela, ke inkxaso iyasilela.
- Imathiriyeli yeFerromagnetic ejikeleze intambo edityanisiweyo ye-slack. I-OPGW ithwala i-induced yangoku ngokuqhubekayo kunye nempazamo yangoku ngamaxesha athile. Ikhebula le-coiling slack ngaphakathi kwesakhelo sokugcina intsimbi, okanye ukuyibophelela ngocingo lwentsimbi, iziphatha njengokongeza izinto ezingundoqo kwi-transformer - i-voltage ye-inter-turn induced iyenyuka kwaye itshise ngemisonto. Ukugquma, Izakhelo zokugcina ezingezizo-magnetic kunye ne-aluminiyam ebopha iteyiphu iyayinqanda.
Ingcebiso yePro yabathengi: Xa uvavanya ucaphulo lwe-OPGW, jonga ngaphaya kwentambo. Buza ukuba umthengisi ubonelela ngantoniiphakheji yokuphelisa - ukugquma izibophelelo ezisezantsi, iifreyimu zokugcina iintambo ezingenamagnetic, Ukuvalwa kwesplice, izixhobo zokubeka phantsi. Intambo enexabiso eliphantsi ene-downlead ephuculweyo kulapho umngcipheko wexesha elide uhlala khona. Sinikezela ngekhebula kunye neseti ye-accessory - ukufakwa kwangaphambili, ii-vibration dampers, amakhonkco ohlelo, ukuvalwa kwe-splice kunye neeracks zokugcina - phantsi kwewaranti enye, ngokukodwa ke ujongano phakathi kwabo akukho ndawo ingwevu.
Umgca ongezantsi-imibuzo emithathu omele uyibuze ngaphambi kokuba nabani na akucaphule
Tsiba uthelekiso lweempawu. Le mibuzo mithathu isombulula uninzi lwesigqibo:
- Ngaba lo mgca unocingo olungaphezulu komhlaba, kwaye umnini uza kuyibuyisela endaweni yayo? Hayi → ADSS. Ewe → I-OPGW ikwitheyibhile ngokwenene.
- Sesiphi esona sithuba side, kwaye zithini iimeko zomoya kunye nomkhenkce apho? Ngaphezulu 300 m ilawula ngaphandle ibhatyi enye ADSS ngoko nangoko. Iimeko zonxweme okanye zomkhenkce ziyayikhupha nakweyiphi na indawo.
- Yintoni ekwikowuteshini ngaphandle kwentambo? Ikhompawundi yebhatyi kunye nobukhulu bodonga lwe-ADSS. I²t kunye noxhaso lweDC lwe-OPGW. Izifakelo, Ukuvalwa kwe-splice kunye ne-hardware esezantsi kuzo zombini. Iikowuti ezimbini zithelekiseka kuphela xa zinomthamo ofanayo.
Ixesha lokwenziwa kwemveliso alifane liqhube isigqibo, kodwa kubalulekile ukwazi: sithengisa 12 ukuya kwi-48-fiber ADSS ene-a 1 km ubuncinane oda, kunye neenqanawa ze-OPGW eziqhelekileyo kwi- 3 km ubuncinane ngesiqhelo 15 ixesha lokuhamba ngosuku lokusebenza. Ukukhutshwa kwemvume kudla ngokuthatha ixesha elide kunezo zombini.
Andiqinisekanga ukuba yeyiphi ehambelana nomgca wakho? Umvelisi owakha zombini i-ADSS yebhatyi enye, Ibhatyi ephindwe kabini ye-ADSS kunye ne-OPGW ayinasizathu sokukukhokelela kwenye yazo. Sithumelele iklasi yombane, iprofayile yespan kunye nokuba umgca mtsha okanye ukwinkonzo, kwaye siza kukuxelela ukuba yeyiphi kwezi zintathu zilingana - kubandakanywa xa impendulo iyeyona inexabiso eliphantsi. Iintambo zeADSS · Iintambo ze-OPGW
Amanani obugcisa kwesi sikhokelo avela kwiinkcukacha zethu zemveliso kunye novavanyo lwefektri. I-Voltage-class kunye nesikhokelo sobude bubonisa umkhuba woshishino oluqhelekileyo kwaye kufuneka luqinisekiswe ngokuchasene nekhowudi yegridi kunye nemigangatho yoyilo esebenzayo kwiprojekthi yakho..
