OPGW optical cable yog siv rau ntawm 500KV, 220KV, 110KV voltage theem kab.Muaj kev cuam tshuam los ntawm cov khoom xws li kab hluav taws xob hluav taws xob, kev nyab xeeb, thiab lwm yam, nws feem ntau yog siv rau hauv cov kab tsim tshiab.Overhead ground wire composite optical cable (OPGW) yuav tsum muaj kev ntseeg siab hauv qhov chaw nkag los tiv thaiv cov kab hluav taws xob los ntawm kev tawg los ntawm kev cuam tshuam hluav taws xob thiab cuam tshuam thaum lub caij luv luv tshwm sim hauv kab.GL Technology raws li 17 xyoo dhau los ntawm fiber ntau optic cable chaw tsim tshuaj paus nyob rau hauv Suav teb, peb yuav qhia koj cov ntsiab lus tseem ceeb uas yuav tsum tau rau hauv av ntawm lubOPGW kho qhov muag cable.
Ua tib zoo mloog cov ntsiab lus hauv qab no rau cov kev cai hauv av:
1. Cov txheej txheem hauv av ntawm cov khoom siv kho qhov muag ntawm lub thawv splice ntawm cov qauv: sab saum toj ntawm cov qauv, qhov qis tshaj qhov chaw ruaj khov (ua ntej qhov seem cable) thiab qhov kawg ntawm cov khoom siv kho qhov muag yuav tsum txuas nrog cov qauv siv hluav taws xob txhim khu kev qha. kev sib txuas los ntawm kev sib piv rau cov xaim hauv av.Cov hlua txuas ntxiv thiab lub thawv txuas thiab cov thav duab yuav tsum tau kho nrog kev sib txuam kho fixtures thiab insulating roj hmab.Cov hlua txuas ntxiv yuav tsum tau kho ntawm qhov seem cable khib nrog θ1.6mm galvanized hlau hlau, thiab cov ntsiab lus khi yuav tsum tsis txhob tsawg dua 4, thiab cov hlua txuas ntxiv thiab cov hlua txuas ntxiv yog nyob rau hauv kev sib cuag zoo.
2. Kev sib txuas hauv av lub thawv kho qhov muag cable grounding txoj kev: Txhim khu kev txuas hluav taws xob yuav tsum tau ua rau lub thav duab nyob rau sab saum toj ntawm lub thav duab thiab lub taub hau ntawm cov hlua txuas ntxiv los ntawm kev sib koom ua ke ntawm cov khoom siv hauv av.
3. Cov hlau lead ntawm optical cable yuav tsum ncaj thiab zoo nkauj.Nruab ib qho kev txhim kho txhua txhua 1.5m-2m kom tsis txhob muaj kev sib txhuam ntawm cov khoom siv kho qhov muag thiab cov pej thuam.Cov hlau lead-down optical cable thiab cov thav duab puab ntawm qhov chaw nres tsheb yuav tsum tau kho nrog kev sib txuam kho fixtures thiab insulating roj hmab, thiab qhov kev ncua deb ntawm qhov txo qis optical cable thiab tus ncej yuav tsum tsis pub tsawg tshaj 20mm.
4. OPGW yuav tsum tau txuas nrog rau hauv av davhlau ya nyob twg ntawm tus ncej nrog ib tug sib piv rau lub hauv av xaim, OPGW sab yuav tsum tau txuas nrog ib tug parallel zawj clamp, thiab thav duab sab yuav tsum tau txuas nrog bolts, thiab tsis muaj vuam raug tso cai.
5. Cov kev taw qhia kho qhov muag cable coj los ntawm lub thawv sib txuas ntawm lub khib nyiab mus rau qhov chaw faus ntawm lub cable trench yog tiv thaiv los ntawm kub-dip galvanized steel kav, thiab ob qhov kawg ntawm cov yeeb nkab steel yog kaw nrog fireproof av nkos rau waterproofing.Cov yeeb nkab steel muaj kev ntseeg siab txuas nrog cov phiaj xwm hauv av hauv chaw nres tsheb.Txoj kab uas hla ntawm cov yeeb nkab steel yuav tsum tsis pub tsawg tshaj 50mm.
6. Cov kab hluav taws xob kho qhov muag tau teeb tsa los ntawm hauv pem teb-sawv cable lub thawv yog coj los ntawm tus ncej mus rau faus ib feem ntawm lub cable trench thiab tiv thaiv los ntawm kub-dip galvanized steel kav, thiab insulated los ntawm insulating lub tes tsho, thiab ob kawg yog kaw nrog. fireproof av nkos rau waterproofing.Qhov seem ntawm lub thawv cable thiab cov yeeb nkab steel muaj kev ntseeg siab txuas nrog rau cov phiaj xwm hauv av hauv chaw nres tsheb.Txoj kab uas hla ntawm cov yeeb nkab steel yuav tsum tsis pub tsawg tshaj 50 hli, txoj kab uas hla ntawm lub tes tsho insulating yuav tsum tsis txhob tsawg dua 35 hli, thiab lub vojvoog dabtsi yog khoov ntawm cov yeeb nkab steel yuav tsum tsis pub tsawg dua 15 npaug ntawm txoj kab uas hla ntawm cov yeeb nkab steel.Txhim khu kev rwb thaiv tsev ntawm kev sib txuas lub thawv, kho qhov muag cable reel thiab lub thawv lub cev.
