Cov hlau loj ntawmmedium voltage hlaufeem ntau yuav tsum tsis pub tsawg tshaj 70mm ². Nyob rau hauv nruab nrab voltage fais fab systems, xaiv nruab nrab voltage hlau conductors yuav tsum tau xav txog cov kev cai thiab kev khiav hauj lwm tej yam kev mob ntawm lub system.
Kev xaiv ntawm hlau loj rau nruab nrab voltage cables feem ntau yog raws li nram no:
System voltage theem: Qhov voltage ntawm nruab nrab voltage fais fab systems feem ntau yog nruab nrab ntawm 3kV thiab 35kV. Kev xaiv ntawm nruab nrab voltage hlau conductors txawv nyob ntawm qhov voltage theem ntawm lub system.
Load yuav tsum: Kev xaiv ntawm nruab nrab voltage hlau conductors kuj yuav tsum tau xav txog load yuav tsum tau kom paub tseeb tias cov conductors muaj peev xwm nqa tau qhov yuav tsum tau tam sim no thiab tsis txhob overload cov xwm txheej.
Ib puag ncig tej yam kev mob: txawv ib puag ncig, xws li kub, av noo, thiab lwm yam, kuj tuaj yeem cuam tshuam rau kev xaiv ntawm cov xov hlau. Nyob rau hauv ib puag ncig hnyav, nws yuav tsim nyog xaiv qhov loj me ntawm nruab nrab voltage cable conductors kom muaj kev nyab xeeb.
Cov hlau loj loj hauv nruab nrab voltage fais fab system feem ntau yuav tsum tsis pub tsawg tshaj 70mm ². Piv txwv li, nyob rau hauv lub implemen
tation qauv ntawm steel cored aluminium stranded hlau (JL / G1A), ntau specifications muaj xws li 10/2, 16/3, 25/4, 35/6, 50/8, 70/10, thiab lwm yam. nyob rau hauv kev faib khoom.
