Cov qauv sib xyaw ntawm DC cov kab hluav taws xob feem ntau suav nrog cov ntaub thaiv sab nrauv, sab hauv lub plhaub, thiab cov khoom siv hluav taws xob. Cov khoom siv hluav taws xob sib kis tau muaj xws li tooj liab, txhuas cov khoom siv hlau hlau, thiab lwm yam. Cia peb saib cov lus piav qhia ntxaws ntawm cov qauv hauv qab no:
1. Sab nrauv
Lub plhaub sab nraud, tseem hu ua lub tsho tiv thaiv, yog txheej txheej txheej sab nraud ntawm DC fais fab kab. Cov txheej txheej txheej txheej txheej no ua lub luag haujlwm hauv kev tswj cov kab hluav taws xob DC. Cov txheej txheej txheej muaj cov yam ntxwv zoo xws li kub tsis kam, tsis kub tsis kam, tsis kam mus rau ntuj lub teeb, cov yam ntxwv zoo winding, lub neej ua haujlwm ntev, thiab cov khoom siv raw khoom zoo ib puag ncig.
2. Sab hauv sheath
Sab hauv sheath, tseem hu ua rwb thaiv tsev sheath, yog ib qho tseem ceeb ntawm cov txheej txheem nruab nrab ntawm DC fais fab. Lub rwb thaiv tsev sheath yog txheej rwb thaiv tsev, uas yog ib txheej ntawm raw khoom siv los tiv thaiv lub cable ntawm shielding txheej thiab cov tub ntxhais. Nws feem ntau yog ua los ntawm polyvinyl chloride yas los yog high-density polyethylene, thiab kuj muaj cov pa luam yeeb tsawg thiab halogen-dawb cov ntaub ntawv. Raws li cov txheej txheem yuav tsum tau thov, lub cable sheath yuav tsum tau siv los tiv thaiv nws los ntawm yooj yim kov cov dej, roj los yog lwm yam khoom, tiv thaiv lub rwb thaiv tsev txheej los ntawm damp, thiab tiv thaiv tsis zoo tus cwj pwm ntawm cable sheath. Xyuas kom muaj kev ruaj ntseg ntawm DC fais fab qaum, kom tooj liab hlau thiab roj yuav tsis ncaj qha rau ib qho luv luv Circuit Court tej yam kev mob, thiab cov ntaub ntawv raw ntawm lub rwb thaiv tsev sheath yuav tsum mos kom ntseeg tau tias nws yuav tsum tau zoo embedded nyob rau hauv lub puab txheej.
3. Tooj hlau
Copper hlau yog ib qho tseem ceeb ntawm DC fais fab kab, thiab nws tsuas yog ua haujlwm nruab nrab rau tam sim no thiab voltage. Qhov ntom ntawm tooj liab tuaj yeem cuam tshuam ncaj qha rau qhov zoo ntawm DC fais fab kab. Cov khoom siv ntawm DC fais fab cables kuj yog lub hauv paus tseem ceeb rau kev tswj xyuas nruj, thiab tag nrho cov nyiaj thiab kev hloov pauv ntawm cov xov tooj tooj liab kuj yog ib qho laj thawj rau kev txiav txim siab.
