olyvinyl chloride sheathed cable khoom (PVC sheathed cable khoom) yog cov khoom siv ntau yam thiab ruaj khov siv hauv kev tsim cov cables rau ntau yam kev siv. Cov khoom siv no muaj ntau yam txiaj ntsig, ua rau nws muaj kev xaiv nrov hauv kev lag luam.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm PVC sheathed cable khoom yog nws cov khoom zoo heev rwb thaiv tsev. PVC yog lub npe hu rau nws lub zog dielectric siab, uas ua rau nws muaj kev ntseeg siab xaiv rau insulating cables thiab tiv thaiv lawv los ntawm hluav taws xob txaus ntshai. Qhov no ua kom muaj kev nyab xeeb thiab kev ua haujlwm ntawm cov kab hluav taws xob, ua rau nws tsim nyog rau kev siv ntau yam khoom siv hluav taws xob thiab kev sib txuas lus.
Tsis tas li ntawd, PVC sheathed cable cov ntaub ntawv yog resistant rau ya raws thiab tshuaj, ua rau nws haum rau sab nraum zoov thiab hnyav ib puag ncig. Qhov no ua rau cov kab hluav taws xob ruaj khov thiab siv tau ntev, txo qhov xav tau kev tu thiab hloov ntau zaus.
