Raws li lawv cov kev npaj siv, hluav taws xob hluav taws xob tuaj yeem raug cov kab ke sib txuas, tswj cov cable, kev sib txuas lus cables, thiab cable kho qhov muag. Raws li lawv cov qauv txheej txheem, lawv tuaj yeem muab faib ua ntej rau hauv cov xees ua haujlwm thiab cov cab kuj. Tsis tas li ntawd, hluav taws xob hluav taws xob tuaj yeem raug faib ua raws ntau yam, xws li lawv cov khoom siv tua tsiaj, thiab cov khoom hluav taws xob, thiab qib voltuag.
Lub zog loj rau kev sib txawv cov hom phiaj sib txawv muaj cov yam ntxwv sib txawv thiab cov chaw thov. Piv txwv li, kev sib kis tau cov kab ke yog feem ntau siv rau high- voltage thiab siab} theem siab. Tswj cov cable, txawm li cas los xij, muab cov txiaj ntsig xws li kis tau hluav taws xob hluav taws xob thiab txhim kho cov siv hauv kev tswj hwm kev tswj hwm thiab tshuaj xyuas cov tshuab. Thaum siv hluav taws xob hluav taws xob, nws yog ib qho tseem ceeb kom xaiv cov hom cable uas tsim nyog thiab cov kev qhia tshwj xeeb raws li lawv cov ntawv thov tshwj xeeb.
