Cov hlau muaj ib lossis ntau qhov hloov pauv hloov pauv hauv lub teeb, mos sheath; cables muaj ib los yog ntau tshaj insulated conductors, them nyob rau hauv ib tug tawv txheej txheej ntawm hlau los yog roj hmab. Ob lub cables thiab cov xov hlau feem ntau muaj peb yam: ib tug tub ntxhais hlau, insulating sheath, thiab ib tug tiv thaiv sab nrauv sheath. Cov yam ntxwv ntawm cov kab hluav taws xob muaj raws li hauv qab no: CEF-EPR roj hmab rwb thaiv tsev, chloroprene roj hmab sheath, marine nplaim taws- retardant fais fab cable. CVV-PVC rwb thaiv tsev, PVC sheath, marine nplaim taws- hluav taws xob cable. Oxygen chamber thaiv feem ntau siv BV, BX, RV, thiab RVV series cables. BV-Copper core PVC insulated hlau, nrog rau lub sijhawm ntev - ua haujlwm kub ntawm 65℃thiab qhov ntsuas kub tsawg kawg yog -15℃, thiab kev ua haujlwm voltage ntawm 500V AC thiab 1000V DC. Nws tuaj yeem ntsia tau rau sab hauv tsev lossis sab nraum zoov hauv qhov chaw ruaj khov, nthuav tawm lossis zais. BX-Copper core roj hmab insulated hlau, nrog rau qhov siab tshaj plaws ua haujlwm kub ntawm 65 degree, thiab tuaj yeem ntsia tau rau hauv tsev. RV - PVC insulated ib leeg-ntxhais hloov tau yooj yim xaim, nrog lub siab tshaj plaws kev khiav hauj lwm kub ntawm 65℃thiab ib tug yam tsawg kawg nkaus kev khiav hauj lwm kub ntawm -15 degree, kev khiav hauj lwm voltage ntawm 250V AC thiab 500V DC, siv rau sab hauv xov ntawm cov twj paj nruag thiab khoom siv.
RVV - Copper-core PVC insulated thiab sheathed saj zawg zog xaim, nrog rau kev tso cai ntev -lub sij hawm ua hauj lwm kub ntawm 105℃thiab ib tug khiav hauj lwm voltage ntawm 500V AC thiab 1000V DC, siv nyob rau hauv ntub ib puag ncig, yuav tsum tau muaj kev tiv thaiv mechanical siab, thiab yuav tsum nquag txav thiab flexing. Qhov tseeb, tsis muaj qhov sib txawv ntawm "hlau" thiab "cable." Cov khoom uas muaj cov cores me me, txoj kab uas hla me me, thiab cov qauv yooj yim feem ntau hu ua cov xov hlau. Uninsulated xov hlau yog hu ua liab qab xov hlau, thaum lwm tus hu ua cables. Cov neeg siv hluav taws xob uas muaj tus ntoo khaub lig loj dua- ntu ntu (ntau dua 6 square millimeters) yog hu ua cov xov hlau loj, thaum cov kab me me - ntu ntu (tsawg dua lossis sib npaug li 6 square millimeters) hu ua cov xov hlau me. Insulated wires kuj hu ua ntaub xov hlau. Qhov no yooj yim dua thiab nkag siab yooj yim dua! Cables feem ntau muaj ob lossis ntau txheej ntawm rwb thaiv tsev, feem ntau yog ntau-core, thiab raug mob ntawm cable reels. Qhov ntev yog feem ntau ntau dua 100 meters. Cov hlau feem ntau yog ib leeg-insulated, ib leeg-core, thiab tuaj hauv 100-meter reels, tsis muaj reels.
Cov qauv kab ntau: VV sawv cev rau polyvinyl chloride rwb thaiv tsev (thawj V), polyvinyl chloride sheath (V thib ob); YJV22 stands rau cross-txuas polyethylene rwb thaiv tsev (YJ), polyvinyl chloride sheath (V), steel daim kab xev enclosure (22). Cov qauv nrog "ZR" lossis "FR" yog nplaim taws- cov kab hluav taws xob (hlau). Cov qauv nrog "L" yog txhuas hlau. Cov qauv hlau yog qhov yooj yim: BVV - polyvinyl chloride insulated thiab sheathed tooj liab tub ntxhais hlau, BV - polyvinyl chloride insulated tooj liab tub ntxhais hlau, BYJ - tooj liab core cross- txuas polyolefin insulated hlau, BVR - polyvinyl chloride insulated tooj liab tub ntxhais saj zawg zog hlau, BX - roj hmab insulated tooj liab tub ntxhais hlau, RHF - neoprene sheathed tooj liab core saj zawg zog hlau.
