Txawm hais tias cov kab hluav taws xob nruab nrab muaj qhov hluav taws xob ntau dua, lawv tsis tuaj yeem hloov cov kab hluav taws xob tsawg. Vim hais tias ob qho tib si siv nyob rau hauv cov xwm txheej sib txawv thiab cov scopes, nws yog ib qho tsim nyog los xaiv thiab siv lawv raws li qhov xwm txheej tiag tiag.
1. Kev saib xyuas kev ruaj ntseg
Qhov voltage ntawm nruab nrab voltage cables kuj yog siab, thiab lawv installation thiab txij nkawm yuav tsum tau kev txawj ntse thiab khoom siv. Yog tias siv rau hauv cov hluav taws xob hluav taws xob tsawg, nws yuav ua rau muaj kev nyab xeeb ntxiv.
2. Qhov teeb meem nqi
Txawm hais tias cov kab hluav taws xob nruab nrab muaj qhov zoo dua thiab kev ua haujlwm zoo, cov nqi sib xws kuj tseem siab dua, ua rau lawv tsis muaj txiaj ntsig rau kev siv hluav taws xob tsawg.
3. Fais fab kis tau zoo
Cov kab hluav taws xob nruab nrab yog tsim rau cov hluav taws xob hluav taws xob sib kis tau zoo, thaum cov hluav taws xob tsis tshua muaj hluav taws xob tsim nyog rau kev xa hluav taws xob tsawg. Yog li ntawd, yog tias cov kab hluav taws xob nruab nrab siv los hloov cov hluav taws xob qis qis, yuav muaj kev pheej hmoo ntawm kev txo cov hluav taws xob xa hluav taws xob.
Nyob rau hauv luv luv, nruab nrab voltage cables thiab low voltage cables yog ob hom cables uas sib txawv voltage theem, txhua tus muaj nws tus kheej daim ntawv thov nyob rau hauv ntau yam thiab ntau yam. Txawm hais tias cov kab hluav taws xob nruab nrab tuaj yeem siv tau hauv qee qhov hluav taws xob qis, lawv tsis tuaj yeem hloov cov kab hluav taws xob tsawg. Daim ntawv thov cable tsim nyog yuav tsum raug xaiv raws li qhov xwm txheej tiag tiag.
