olyvinyl chloride sheathed cable material (PVC sheathed cable material) chinhu chinochinja-chinja uye chakasimba chinoshandiswa mukugadzira tambo dzemhando dzakasiyana dzekushandisa. Ichi chinyorwa chinopa huwandu hwakawanda hwemabhenefiti, zvichiita kuti ive sarudzo yakakurumbira mukati meindasitiri.
Imwe yemabhenefiti makuru ePVC sheathed tambo zvinhu ndeye yakanakisa insulation zvivakwa. PVC inozivikanwa nekusimba kwayo kwepamusoro dielectric, iyo inoita kuti ive sarudzo yakavimbika yekuisa insulating tambo uye kudzidzivirira kubva kunjodzi dzemagetsi. Izvi zvinovimbisa kuchengetedza uye kushanda zvakanaka kwetambo, zvichiita kuti ive yakakodzera kushandiswa mumhando dzakasiyana-siyana dzemagetsi nekukurukurirana.
Pamusoro pezvo, PVC sheathed cable material inopesana nekunyorova uye makemikari, zvichiita kuti ive yakakodzera kunze uye nehutsinye mamiriro ekunze. Izvi zvinoita kuti tambo igare yakasimba uye inogara kwenguva refu, ichideredza kudiwa kwekugara uchigadzirisa uye kutsiva.
