Niaj hnub no, peb feem ntau qhiaTsibntsuas los txhim kho cov hluav taws xob tiv thaiv ntawm ADSS optical cables.
(1) Kev txhim kho ntawm kev taug qab resistant optical cable sheath
Lub cim ntawm hluav taws xob corrosion nyob rau saum npoo ntawm qhov kho qhov muag cable nyob ntawm peb yam xwm txheej, ib qho ntawm qhov tseem ceeb, xws li hluav taws xob teb, ya raws thiab qias neeg.Yog li ntawd, nws raug pom zoo kom siv tag nrho OPGW kho qhov muag cables siv rau ntawm 110kV tshiab thiab tshaj cov kab sib txuas;cov kab hauv qab 110kV siv ADSS optical cables nrog kev tiv thaiv AT sheath.
(2) Txhim kho kev tsim thiab tsim cov khoom siv kho qhov muag
Txhawm rau txhawm rau txhim kho kev nyab xeeb ntawm ADSS optical cable ntawm cov kab sib kis, nws tuaj yeem txiav txim siab txo qhov sag ntawm ADSS optical cable erection, uas yog, ua kom lub zog tensile ntawm ADSS optical cable thaum txo nws cov creep. tus nqi.Thaum nyob rau hauv cov xwm txheej hnyav xws li cua thiab xuab zeb, qhov nkag thiab elongation ntawm qhov kho qhov muag cable yuav tsis tshwm sim los ntawm cov nyhuv ntawm cov cua, uas yuav txo qhov kev nyab xeeb ntawm nws thiab cov kab sib kis thiab ua rau hluav taws xob corrosion.
Hauv kev tsim ntawm optical cable, peb yam tau hais txog:
1. Ua kom cov xov paj aramid kom txo tau cov sag ntawm ADSS optical cable;
2. Siv cov modulus siab thiab siab zog aramid fiber ntau uas nyuam qhuav tshawb fawb los ntawm DuPont, nws cov modulus yog 5% siab dua li cov pa aramid fiber ntau, thiab nws lub zog yog li ntawm 20% siab dua li cov pa aramid fiber ntau, uas ntxiv txo cov creep ntawm ADSS kho qhov muag cable;
3. Ua kom lub thickness ntawm cov ntaub thaiv npog los ntawm cov pa 1.7mm mus rau ntau tshaj 2.0mm, thiab tib lub sij hawm xyuas kom nruj thiab smoothness ntawm cov molecules ntawm optical cable extruded sheath nyob rau hauv ntau lawm los txhim kho cov hluav taws xob corrosion kuj. ntawm optical cable.
(3) Xaiv qhov tsim nyog kho qhov muag cable dai taw tes
Xaiv qhov tsim nyog kho qhov muag cable dai taw tes tuaj yeem txo qhov tshwm sim ntawm hluav taws xob corrosion.
Yog tias tsis muaj qhov tsim nyog dai ntawm txoj kab lossis qhov taw tes dai yuav tsum siab rau qhov tshwj xeeb, qee qhov kev ntsuas yuav tsum tau ua.Cov kev pom zoo kho yuav raug suav hais tias yog raws li hauv qab no: ①Ntxiv cov ntawv hlau lossis hlau nplhaib ua ib daim ntaub thaiv nyob ze ntawm qhov kawg ntawm cov khoom siv ua ntej twisted, uas tuaj yeem txhim kho cov kev faib tawm ntawm cov hluav taws xob zoo thiab txo qhov tshwm sim ntawm corona paug: ② Lub optical cable nyob ze ntawm lub fixture Siv arc-resistant insulating daim kab xev los qhwv ib ncig ntawm lub nto los tswj qhov rov tshwm sim ntawm arcs;③ Spread non-linear silicone insulating pleev xim rau ntawm qhov chaw ntawm qhov kho qhov muag cable nyob ze ntawm lub fixture.Lub luag haujlwm ntawm cov xim insulating yog maj mam hloov cov hluav taws xob hluav taws xob ntawm txoj haujlwm txheej kom txo tau qhov muaj peev xwm ntawm corona thiab cov pa phem flashover.
(4) Txhim kho txoj kev teeb tsa ntawm fittings thiab shock absorbers
Txhim kho txoj kev teeb tsa ntawm cov fittings thiab kev poob siab absorbers tuaj yeem txhim kho qhov induction hluav taws xob teb ib puag ncig ze fittings thiab txo qhov tshwm sim ntawm hluav taws xob corrosion.Nruab ib lub nplhaib tiv thaiv kab mob rau ntawm qhov haum txog 400 hli ntawm qhov kawg ntawm cov hlua khi sab hauv, thiab nruab ib qho kev taug qab-tiv thaiv kab mob khaub thuas poob siab txog li 1000 hli los ntawm qhov kawg ntawm lub nplhaib tiv thaiv kab mob.Nyob rau hauv induced hluav taws xob teb lub zog ntawm 15-25kV, qhov kev ncua deb ntawm lub nplhaib tiv thaiv ntsuas thiab cov kauv poob siab absorber yuav tsum tau khaws cia siab tshaj 2500mm kom txo tau qhov tshwm sim ntawm hluav taws xob corrosion nyob rau hauv lub nruj txoj hauj lwm ntawm ADSS cable thiab lub kauv shock absorber. .Tus naj npawb ntawm cov kauv poob siab absorbers siv yog txiav txim los ntawm lub suab ntawm cov kab.
Los ntawm txoj kev txhim kho kev txhim kho no, lub nplhaib tiv thaiv corona tuaj yeem txhim kho qhov chaw hluav taws xob zoo thaum kawg ntawm cov khoom siv ua ntej twisted, thiab tuaj yeem ua rau kom muaj zog corona ntau dua ib zaug.Nyob rau tib lub sijhawm, cov tshuaj tiv thaiv kev taug qab kauv poob siab absorber tuaj yeem tiv thaiv hluav taws xob corrosion ntawm lub shock absorber.Kev puas tsuaj rau lub fiber optic cable.
(5) Txo kev puas tsuaj rau cov hlua khi thaum tsim kho
Nyob rau hauv lub installation ntawm optical cable racks, nws raug pom zoo tias thaum xaiv kho qhov muag cable fittings, kho vajtse manufacturers yuav tsum tau nruj me ntsis customize lub sab nraud txoj kab uas hla ntawm ADSS optical cable, thiaj li yuav xyuas kom meej tias tom qab installation, qhov sib txawv ntawm cov strands. cov fittings thiab optical cable raug txo kom tsawg, thiab ntsev yog txo.Cov hmoov tshauv nkag mus rau hauv lub seam nruab nrab ntawm cov twisted hlau fittings thiab optical cable.Nyob rau tib lub sij hawm, rau tensile hardware, drape hardware, tiv thaiv hlau, thiab lwm yam, cov khoom muab los ntawm lub hardware chaw tsim tshuaj paus yuav tsum du nyob rau hauv ob kawg ntawm cov twisted hlau los tiv thaiv khawb ntawm lub cable sheath.Qhov kawg ntawm cov xov hlau sib tw yuav tsum yog hauv av tiaj tus thaum cov neeg ua haujlwm tsim kho ua haujlwm los tiv thaiv kev puas tsuaj rau cov hlua cable.Cov kev ntsuas no tuaj yeem txo qhov tsub zuj zuj thiab kev yug me nyuam ntawm cov plua plav qias neeg hauv cov kab nrib pleb ntawm cov fittings thiab cov tawv nqaij tawg ntawm qhov chaw ntawm cov khoom siv kho qhov muag, thiab txo qhov inducement ntawm hluav taws xob corrosion.
