E fetohang 3 - Kaho e Ncha kapa Retrofit, le Hore na U ka Khaotsa

Phapang ena e etsa qeto ea merero e mengata ho feta theko e etsang, mme e petsoha hantle.

Mohala o mocha o hloka terata ea fatše ho sa tsotelehe. Leha ho le joalo, tora e ntse e raloa, ho lata ho ntse ho baloa leha ho le joalo, mme basebetsi ba likhoele ba teng setšeng leha ho le joalo. Ho khetha OPGW mothating ona ho bolela hokeketso theko holim'a terata ea fatše e bonolo - u reka fiber, ho se reke lenaneo le arohaneng la ho kenya.

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. Hobane ha e na tšepe, e ka kenngoa libakeng tse ling tsa litora ntle le ho fetoha karolo ea tsamaiso ea motlakase.

Ka ho instola tse phelang-line ka ho khetheha: kaho ea dielectric tsohle e etsa hore ho khonehe ka molao-motheo. Hore na e lumelletsoe ho tsoela pelehao line e itšetlehile ka sehlopha sa voltage, mekhoa ea ts'ebetso ea ts'ebetso e sebetsang, litšoaneleho tsa basebetsi le tumello ea monga thepa.

Ho e Kopanya - The Four-Variable Selection Matrix

Mola o mong le o mong o ka tlase o na le likhothaletsole boemo bo e phetholang. Boemo ba ho phethoha ke karolo ea bohlokoa, hobane morero oa hau o tla qetella o otla e le 'ngoe.

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. Ea pele, 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. Around 30% spare capacity is a common planning allowance.

Ea bobeli, respect the trade-off. More fibers means a heavier, thicker cable, which reduces achievable span. Our single-jacket ADSS runs 4 ho 144 fibers as standard, ka 288 available on request when the span stays near 100 m. Double-jacket reaches 288 as standard and 576 ka kopo. OPGW tops out at 96 likhoele.

Pro Tip bakeng sa Bareki: Etsa qeto ea palo ea fiberpele u phethela tekanyo ea span, eseng kamora. Fiber count e fetola boima ba cable, boima ba cable bo fetola tsitsipano, 'me tsitsipano e fetola nako eo thapo e ka e tšoarang. Ho khutlisa taelo eo ke kamoo merero e qetellang e odara bocha.
