I-olyvinyl chloride sheathed cable material (i-PVC sheathed cable material) iyimpahla eguquguqukayo futhi ehlala isikhathi eside esetshenziswa ekukhiqizeni izintambo zezinhlelo zokusebenza ezahlukahlukene. Lesi sihloko sinikeza izinzuzo eziningi, okwenza kube ukukhetha okudumile ngaphakathi kwemboni.
Enye yezinzuzo eziyinhloko ze-PVC sheathed cable material yizindawo zayo ezinhle kakhulu zokuvikela. I-PVC yaziwa ngamandla ayo aphezulu e-dielectric, okwenza kube ukukhetha okuthembekile kwezintambo zokuvikela nokuvikela ezingozini zikagesi. Lokhu kuqinisekisa ukuphepha nokusebenza kahle kwekhebula, okwenza ifaneleke ukusetshenziswa ezinhlobonhlobo zezinhlelo zikagesi nezokuxhumana.
Ukwengeza, i-PVC sheathed cable material imelana nomswakama kanye namakhemikhali, okwenza ifanelekele izimo zemvelo zangaphandle nezinzima. Lokhu kwenza ikhebula liqine kakhulu futhi lihlale isikhathi eside, kunciphisa isidingo sokugcinwa njalo nokushintshwa.
