RVS hlau yog lub npe tag nrho ntawm tooj liab tub ntxhais polyvinyl chloride insulated stranded kev twb kev txuas nrog saj zawg zog xaim, strands ntawm saj zawg zog hlau, tsab ntawv "R" txhais tau tias saj zawg zog hlau, tsab ntawv "V" txhais tau tias polyvinyl chloride, uas yog, nws cov ntsiab lus ntawm cov ntaub ntawv, tsab ntawv. "S" txhais tau tias "twisted khub" txhais tau tias. Raws li kev sib tw-pair hlau, tus neeg xyuas pib: stranded liab qab tooj liab hlau (BC) los yog tinned tooj liab hlau (TC) nyob rau theem no, cov hlau no feem ntau yog siv hauv hluav taws tua hluav taws, los yog hu ua "kab hluav taws". Cov xov hlau tseem muaj nyob rau hauv cov qauv hluav taws kub thiab hluav taws kub. Tsab ntawv S stands rau twisted khub; Tsab ntawv R stands rau qaum; Tsab ntawv V stands rau polyvinyl chloride American standard tooj liab underground hlau, rated voltage 300/300V, haum rau sab hauv tsev nteg thiab underground nteg, nteg xav tau ib tug galvanized steel yeeb nkab raws li kev pab, haum rau cov khoom siv hauv tsev, cov cuab yeej hluav taws xob me, cov cuab yeej thiab fais fab teeb pom kev zoo kab, fais fab filament thiab lwm yam. Rwb thaiv tsev txheej xim liab thiab xiav ob xim, tsim kom paub qhov txawv ntawm txoj cai ntawm cov kab nruab nrab thiab kab hluav taws, liab thiab xiav core rau hluav taws, tswb thiab lwm yam; Liab thiab dawb tseem ceeb rau kev tshaj tawm, xov tooj; Liab thiab dub cores yog siv rau kev tshaj tawm cov kab. Qhov loj tuaj yeem kho tau, txais tos koj qhov kev sib tham, peb yuav muab cov lus qhia sai li sai tau.
