1. cov khoom siv sib txawv, PVC cable yog tsim los ntawm ib qho los yog ntau yam conductive tooj liab cable, qhov saum npoo yog qhwv los ntawm ib txheej ntawm insulator, tiv thaiv kev sib cuag nrog tus neeg xyuas pib. Tus neeg xyuas pib sab hauv tau muab faib ua ob hom tooj liab liab thiab tinned tooj liab raws li cov qauv qub. Roj hmab hlau, tseem hu ua roj hmab sheathed hlau, yog ib hom ntawm ob chav insulated hlau; Cov tawv nqaij thiab txheej rwb thaiv tsev yog ua los ntawm roj hmab, tus neeg xyuas pib yog tooj liab ntshiab, thiab txheej rwb thaiv tsev feem ntau yog chlorinated polyethylene (CPE).
2. kev siv sib txawv,roj hmab kabyog tsim rau AC rated voltage 300V / 500V thiab 450 / 750V thiab qis dua cov khoom siv hluav taws xob, cov khoom siv hauv tsev, cov cuab yeej hluav taws xob, kev tsim teeb pom kev zoo thiab lub tshuab sab hauv cov kev xav tau ntawm cov khoom muag lossis cov chaw txawb, xws li cov khoom siv hluav taws xob sib txuas lossis kev sib txuas. PVC hlau yog tsuas yog siv rau kev sib txuas hauv cov khoom siv hluav taws xob thiab hluav taws xob.
3. cov yam ntxwv sib txawv, PVC kab yeeb nkab nto yog du, cov kua kuj yog me me, nws tsis scaling, thiab nws tsis haum rau yug me nyuam kab mob. Lub coefficient ntawm thermal expansion yog me me, thiab nws tsis ntsws thiab deform. Roj hmab xaim muaj qee yam huab cua tsis kam thiab qee cov roj ua haujlwm, tuaj yeem tiv taus qhov kev ua haujlwm ntawm cov khoom siv sab nraud loj, muag muag, zoo elasticity, txias tsis kam, tiv thaiv ultraviolet, zoo elasticity, siab zog.
