Qhov sib txawv tseem ceeb ntawm THWN hlau thiab PV hlau yog nyob rau hauv lawv daim ntawv thov scenarios, cov ntaub ntawv rwb thaiv tsev, thiab cov qauv ntawv pov thawj. cov
Daim ntawv thov scenario: THWN hlau feem ntau yog siv sab hauv tsev, feem ntau yog rau cov tsev lag luam thiab cov ntawv thov kev lag luam. PV hlau feem ntau yog siv nyob rau hauv tshwj xeeb ib puag ncig xws li sab nraum zoov lossis photovoltaic systems.
Cov khoom siv rwb thaiv tsev: THWN cov xov hlau siv polyvinyl chloride (PVC) ua cov khoom siv rwb thaiv tsev, nrog ib txheej ntawm cov ntaub nylon sheath rau sab saum toj ntawm cov khoom siv rwb thaiv tsev PVC. Cov khoom siv rwb thaiv tsev thiab cov ntaub qhwv uas PV xov hlau siv tau yog irradiated XLPO, nyob ntawm lawv cov kev thov tshwj xeeb.
Daim ntawv pov thawj tus qauv: thwn hlau ua raws li cov cai ntawm National Electrical Code (NEC) hauv Tebchaws Meskas, thiab cov khoom yuav tsum dhau UL83 daim ntawv pov thawj. Raws li ib qho tshwj xeeb Circuit Court, pv cable yuav tsum tau ua kom tau raws li lwm cov qauv ntawv pov thawj tshwj xeeb, xws li UL4703 ntawv pov thawj, TUV ntawv pov thawj, CPR kuaj, nyob ntawm seb lawv qhov chaw siv tshwj xeeb thiab lub hom phiaj.
Hauv cov ntsiab lus, qhov sib txawv tseem ceeb ntawm THWN xaim thiab PV xaim nyob hauv lawv daim ntawv thov scenarios, cov ntaub ntawv rwb thaiv tsev, thiab cov qauv ntawv pov thawj. Kev xaiv ntawm hom xov hlau twg siv yog nyob ntawm cov ntawv thov tshwj xeeb thiab ib puag ncig
