Nrog rau kev nce qib tas mus li ntawm kev lag luam thiab zej zog thiab kev nrawm nrawm ntawm cov txheej txheem hauv nroog, cov xov hlau ib txwm tsis tuaj yeem ua tau raws li qhov xav tau ntawm kev txhim kho hauv zej zog, yog li cov xov hlau faus rau hauv av tau tshwm sim. Vim yog qhov tshwj xeeb ntawm ib puag ncig uas cov xov hlau hauv av nyob, cov xov hlau yuav raug dej xeb, yog li nws yog qhov tsim nyog ntxiv daim kab xev thaiv dej thaum lub sijhawm tsim khoom los tiv thaiv cov xov hlau.
Daim kab xev thaiv dej semi-conductive cushion yog sib xyaw nrog cov ntaub polyester fiber tsis-woven semi-conductive, cov nplaum semi-conductive, cov tshuaj resin nthuav dav ceev ceev, paj rwb semi-conductive fluffy thiab lwm yam khoom siv. Nws feem ntau siv rau hauv lub hnab tiv thaiv ntawm cov xov hluav taws xob, thiab ua lub luag haujlwm ntawm lub zog hluav taws xob sib xws, thaiv dej, cushioning, tiv thaiv, thiab lwm yam. Nws yog ib qho kev tiv thaiv zoo rau cov xov hluav taws xob thiab muaj lub ntsiab lus tseem ceeb rau kev ua kom lub neej ntawm cov xov hluav taws xob ntev dua.
Thaum lub sijhawm ua haujlwm ntawm lub cable high-voltage, vim yog lub zog tam sim no ntawm lub cable core hauv lub zog zaus teb, cov khoom tsis huv, qhov hws thiab dej seepage hauv txheej rwb thaiv tsev yuav tshwm sim, yog li ntawd lub cable yuav raug rhuav tshem hauv txheej rwb thaiv tsev thaum lub sijhawm ua haujlwm ntawm lub cable. Lub cable core yuav muaj qhov sib txawv ntawm qhov kub thaum lub sijhawm ua haujlwm, thiab lub plhaub hlau yuav nthuav dav thiab cog lus vim yog thermal nthuav dav thiab contraction. Yuav kom hloov kho rau qhov thermal nthuav dav thiab contraction ntawm lub plhaub hlau, nws yog qhov tsim nyog los tawm hauv qhov sib txawv hauv nws sab hauv. Qhov no muab qhov ua tau ntawm dej xau, uas ua rau muaj kev sib tsoo tawg. Yog li ntawd, nws yog qhov tsim nyog los siv cov khoom thaiv dej nrog elasticity ntau dua, uas tuaj yeem hloov pauv nrog qhov kub thaum ua lub luag haujlwm thaiv dej.
Tshwj xeeb, daim kab xev thaiv dej semi-conductive muaj peb ntu, txheej sab saud yog cov khoom siv semi-conductive uas muaj kev tiv taus tensile thiab kub zoo, txheej qis yog cov khoom siv semi-conductive uas mos mos, thiab nruab nrab yog cov khoom siv dej semi-conductive. Hauv cov txheej txheem tsim khoom, ua ntej, cov nplaum semi-conductive raug txuas rau cov ntaub hauv paus los ntawm kev zas xim lossis txheej, thiab cov ntaub hauv paus raug xaiv ua cov ntaub polyester tsis-woven thiab paj rwb bentonite, thiab lwm yam. Cov khoom sib xyaw semi-conductive tom qab ntawd raug kho rau hauv ob txheej semi-conductive los ntawm cov nplaum, thiab cov khoom siv ntawm cov khoom sib xyaw semi-conductive raug xaiv los ntawm polyacrylamide / polyacrylate copolymer los tsim cov dej nqus dej siab thiab cov pa roj carbon dub thiab lwm yam. Daim kab xev thaiv dej semi-conductive muaj ob txheej ntawm cov khoom siv semi-conductive thiab ib txheej ntawm cov khoom siv dej semi-conductive resistive tuaj yeem txiav ua daim kab xev lossis ntswj ua hlua tom qab raug txiav ua daim kab xev.
Yuav kom siv tau daim kab xev thaiv dej tau zoo, yuav tsum khaws daim kab xev thaiv dej rau hauv qhov chaw qhuav, kom deb ntawm qhov chaw hluav taws thiab tshav ntuj ncaj qha. Hnub siv tau yog 6 lub hlis txij li hnub tsim khoom. Thaum khaws cia thiab thauj mus los, yuav tsum ceev faj kom tsis txhob muaj dej noo thiab ua rau daim kab xev thaiv dej puas tsuaj.
