Pom tias muaj cov khw muag khoom dub, dawb, thiab daj, qhov txawv li cas?
Cov kab xev hluav taws xob yog ib hom polyvinyl chloride insulating daim kab xev nrog kev ua haujlwm zoo, kev lag luam thiab siv tau. Nws muaj kev tiv thaiv zoo heev, tiv thaiv ya raws, acid thiab alkali tsis kam thiab tiv thaiv kev hloov pauv ib puag ncig (xws li ultraviolet lub teeb). Polyvinyl chloride daim kab xev muaj lub zog dielectric siab, zoo formability, thiab zoo dua mechanical txij nkawm tuaj yeem tau txais nrog me me.
siv:
Nws yog siv rau kev sib txuas ntawm cov xov hlau thiab cables. Haum rau sab hauv tsev lossis sab nraum zoov lub ntsiab rwb thaiv tsev ntawm txhua cov xov hlau thiab cable txuas nrog qhov hluav taws xob qis dua 600V. Siv los kho cov sheath ntawm high-voltage cable pob qij txha. Siv rau kev txheeb xyuas cov xim ntawm cov hluav taws xob insulated xov hlau thiab cables hauv qab 600V.
Cov lus qhia:
Thaum siv, nws yog coiled nyob rau hauv ib txoj kev semi-pawg. Txhawm rau ua kom cov ntaub qhwv tsis tu ncua thiab tsis tu ncua, nws yuav tsum tau siv los ua kom tau raws li lub zog tensile. Ntawm qhov sib txuas sib txuas, daim kab xev yuav tsum tau qhwv ib ncig ntawm qhov kawg ntawm cov xaim, thiab tom qab ntawd folded rov qab kom tawm hauv lub hnab roj hmab los tiv thaiv kev khawb. Thaum qhwv txheej kawg, nws tsis tuaj yeem ncab kom tiv thaiv tus chij los ntawm rub.
Qhov teeb meem xim yog txiav txim siab raws li lub hwj chim mov. Peb-theem tsib-xaim system suav nrog peb theem xaim (A, B, thiab C xaim), nruab nrab xaim (N xaim) thiab av xaim (PE xaim) ntawm peb theem hluav taws xob.
Tom qab ntawd daim kab xev hluav taws xob raws li tus qauv xaim xim yog: Ib lub xaim daj rau daj hluav taws xob daim kab xev, B xaim ntsuab rau ntsuab hluav taws xob daim kab xev, C hlau liab rau liab hluav taws xob daim kab xev, N hlau xiav rau xiav hluav taws xob daim kab xev, PE hlau daj-ntsuab los yog dub khub Yellow-ntsuab hluav taws xob daim kab xev.
