armored cable tsis tas yuav tsum tau faus rau hauv av, tab sis tsim nyog rau kev faus ncaj qha. Armored cables feem ntau yog siv nyob rau hauv cov xwm txheej hauv av, tshwj xeeb tshaj yog rau kev faus ncaj qha rau hauv cov pob zeb, vim lawv tuaj yeem ua rau cov neeg kho tshuab lub zog ntawm cov cable thiab tiv thaiv kev puas tsuaj.
Txoj kev faus ncaj qha rau ntawm txoj hlua armored yuav tsum tau them sai sai rau cov ntsiab lus hauv qab no:
Hauv qab ntawm qhov khawb av yuav tsum yog cov av mos uas tsis muaj pob zeb lossis lwm cov khib nyiab nyuaj, txwv tsis pub 100 hli tuab txheej ntawm cov av mos lossis xuab zeb yuav tsum tau pw. Cov av nyob ib ncig ntawm lub cable yuav tsum tsis txhob muaj cov khoom uas corrode hlau sheath ntawm lub cable, thiab yuav tsum tau muab tshem tawm thiab hloov nrog av.
Qhov tob faus yuav tsum tsis pub tsawg tshaj 0.7m (nyob rau hauv cov cheeb tsam txias, cables yuav tsum tau muab tso rau hauv qab ntawm lub frozen txheej).
Tom qab kev teeb tsa cable tiav, txheej txheej ntawm cov av mos lossis cov xuab zeb zoo nrog lub thickness ntawm 100 hli yuav tsum tau muab tso rau saum toj, thiab tom qab ntawd npog nrog lub pob zeb tiv thaiv phaj nrog qhov dav dav ntawm 50 hli dhau ntawm ob sab ntawm txoj kab uas hla.
Cov hlau sheath ntawm armored cable yuav tsum ntseeg tau nyob rau hauv ob qho tib si xaus, thiab lub grounding kuj yuav tsum tsis txhob ntau tshaj 10 Ω.
Ntawm qhov chaw uas cov cables hla dhau yam tsis muaj vaj tse nyob ruaj khov, cov ceg txheem ntseeg yuav tsum tau muab faus, thiab cov ceg txheem ntseeg yuav tsum tau muab faus rau ntawm cov pob qij txha thiab khoov.
Yog vim li cas rau grounding armored cable yog ua kom muaj kev nyab xeeb thiab kev ntseeg tau. Grounding tuaj yeem tsav cov cuab yeej tiv thaiv mus ncig, tsis txhob muaj hluav taws xob poob; Nyob rau tib lub sijhawm, nws tuaj yeem ua kom muaj peev xwm ntawm cov txheej thaiv thaiv ntawm txhua qhov tseem ceeb, zam qhov tshwm sim ntawm qhov tshwm sim tawm. Yog tias tsis muaj av, qhov siab tam sim no dhau los ntawm lub cable yuav tsim cov eddy tam sim no nyob rau hauv armored steel sawb, ua rau lub cable kom sov thiab tej zaum yuav ua rau ib tug luv luv Circuit Court los yog hlawv.
