Kev ua haujlwm tseem ceeb ntawm kev ntxig hluav taws xob yog kom ua tiav hluav taws xob rwb thaiv tsev thiab kev txhim kho tshuab, uas muaj ntau qhov hluav taws xob thiab kev ua haujlwm tau tsim. Raws li qhov tshwj xeeb tshaj tawm ntawm kev ua haujlwm voltage, xob laim overvoltage thiab sab nraud overvoltage, tsis muaj kev tawg lossis flashover raws tus nplaim yuav tshwm sim; nyob rau hauv kev tswj hwm lub sijhawm ntev thiab luv luv siv tshuab, tsis muaj kev puas tsuaj lossis yuav puas; hauv lub tshuab tshwj xeeb Tom qab kev ua haujlwm ntev nyob rau hauv hluav taws xob ntsaws thiab ntau yam ib puag ncig ib puag ncig, tsis muaj qhov tsis pom tseeb tshwm sim.
Qhov fittings ntawm cov rwb thaiv tsev tsis ua kom pom qhov pom corona qhov tshwm sim nyob rau hauv qhov hluav taws xob ua haujlwm, thiaj li tsis cuam tshuam rau kev txais tos xov tooj cua lossis TV. Vim tias cov insulators siv nyob rau hauv cov khoom loj, lawv cov kab txuas sib txuas kuj yuav tsum sib pauv hloov. Tsis tas li ntawd, cov qauv kev ua haujlwm ntawm cov insulators tseem xav tau sib txawv hluav taws xob, tshuab, lub cev thiab ib puag ncig cov teeb meem yuav raug kuaj ntawm cov rwb thaiv tsev kom paub meej lawv qhov kev ua tau zoo thiab qhov ua tau zoo, nyob ntawm tus qauv thiab cov xwm txheej ntawm kev siv.
Txij li thaum xyoo 2004, cov nyiaj tau los ntawm kev lag luam tseem ceeb nyob rau hauv Suav teb' s insulator arrester kev lag luam tau txuas ntxiv loj hlob sai, nrog tus nqi nruab nrab txhua xyoo tau ze rau 25%. Nrog kev txhim kho ntawm Tuam Tshoj' s rwb thaiv tsev tsim khoom tsim technology qib, thiab kev nrawm ntawm kev txhim kho hauv kev lag luam nyob rau sab hnub tuaj Asia, South Asia thiab lwm lub teb chaws cov lag luam loj tau txeeb lub sijhawm los tshawb nrhiav thoob ntiaj teb kev ua lag luam, thiab cov nqi xa khoom xa tuaj ntawm kev lag luam nce xyoo los ntawm xyoo. Raws li kev tshawb fawb txog kev kwv yees, kev sib xyaw txhua xyoo kev loj hlob ntawm kuv lub teb chaws' s insulator neeg raug ntes tsim kev lag luam' s muag nyiaj tau los yog 17.83% los ntawm xyoo 2012 txog rau xyoo 2015. s kev muag khoom yuav tau kwv yees li 40.3 billion yuan.
Lub zog hluav taws xob yog kev lag luam tseem ceeb tshaj plaws rau kev lag luam rau cov rwb thaiv tsev. Ntau lub zog tsim hluav taws xob nyob hauv Suav teb nyob rau theem no, xws li kev tsim kho thiab kev tsim kho ntawm cov hluav taws xob hauv nroog thiab hauv nroog, cov phiaj xwm kev xa xov hluav taws xob sab hnub poob-sab hnub poob, txoj haujlwm tsim hluav taws xob hauv qhov chaw tsim hluav taws xob, thiab pib lub UHV khoom lag luam tsis yog rau cov rwb thaiv tsev. neeg ntes kev lag luam. Txoj kev txhim kho tau muab qhov chaw ua lag luam dav dav, tab sis kuj tso cov kev xav tau tshiab rau kev lag luam cov khoom lag luam, txhawb kev kho kom haum rau kev teeb tsa cov qauv kev lag luam ntawm cov neeg ntes cov khoom lag luam thiab kev tsim khoom thev naus laus zis tshiab.
