Simba tambo kazhinji ine core, insulation layer uye layer yekudzivirira.Iyo yakakosha inoshandiswa kuitisa magetsi;Insulation layer ndiyo yakakosha conductor uye inodzivirira layer insulation isolation, kudzivirira kuvuza;Iyo yekudzivirira yekudzivirira inoshandiswa kudzivirira iyo yekuvharisa tambo yetambo kubva pakukuvadzwa kana kunyorova, uye kudzivirira kubuda kwemvura insulating (insulating mafuta).
Hunhu hweakasiyana insulation zvimiro:
(1) Oiri-bepa insulated tambo dzinonyanya kukamurwa kuita viscous impregnated bepa insulation uye asiri kudonha, ayo anowanzo shandiswa mu3-35KV masisitimu.Adhesive impregnated bepa insulated tambo: nyore chimiro, nyore kugadzira, mutengo wakaderera, nyore kuisa uye kugadzirisa, hupenyu hurefu;Haina kukodzera kudonhedza kwakakwira, mafuta ekudzivirira ari nyore kuyerera.Non-drip impregnated bepa insulated cable;Mutengo wepamusoro pane wekunamatira bepa insulation, hupenyu hurefu hwekushanda, hunogona kuita yakakwirira yekudonha kuisa.
(2) Plastic insulated cables akajairika PVC, polyethylene uye crosslinked polyethylene tambo.
Kuwedzera kune yekunze semiconductor shielding layer, kune dhizaini yemhangura bhandi rekudzivirira, basa ravo nderekunetesa mhedzisiro yekunze kwemagetsi emagetsi pa xLPE, kuve nechokwadi chekushanda kwakanaka kwekudzivirira.Copper bhandi shielding rinoshandiswawo sewelding poindi yekudzivirira tambo yepasi.Pamusoro pekuvhara bhandi remhangura, waya matatu macores akazadzwa nemafirita, uye iyo yekunze layer ine matatu-chikamu chakabatana ladle bhandi uye PVC yekunze inodzivirira sleeve.
