ʻO ka olyvinyl chloride sheathed cable material (PVC sheathed cable material) he mea maʻalahi a lōʻihi hoʻi i hoʻohana ʻia i ka hana ʻana i nā kaula no nā ʻano noi. Hāʻawi kēia mea waiwai i ka nui o nā pono, e lilo ia i koho kaulana i loko o ka ʻoihana.
ʻO kekahi o nā pono nui o ka PVC sheathed cable material ʻo ia kona mau waiwai insulation maikaʻi loa. ʻIke ʻia ʻo PVC no kona ikaika dielectric kiʻekiʻe, kahi e koho pono ai no ka insulating cable a pale iā lākou mai nā pōʻino uila. Mālama kēia i ka palekana a me ka pono o ke kaula, kūpono ia no ka hoʻohana ʻana i nā ʻano uila a me nā ʻōnaehana kamaʻilio.
Hoʻohui ʻia, kūpaʻa ʻo PVC sheathed cable material i ka makū a me nā kemika, kūpono ia no nā kūlana o waho a paʻakikī. ʻO kēia ka mea e paʻa loa ai ke kaula a lōʻihi, e hōʻemi ana i ka pono no ka mālama pinepine a me ka hoʻololi.
