Ingakanani i-Square Wire esetyenziswayo kwizibane zobungqina bokudubula

I-200-watt-proof-proof light-proof light-proof ifuna i-0.75mm² ucingo ukuze uqhagamshelwe, ukubambelela ngokungqongqo kwimigangatho yesizwe.

Ngokuqhelekileyo, ukuqinisekisa umsinga ofunekayo kwisibane esingaqhushumba, ubala ngokwahlula amandla ayo ngombane oqhelekileyo we-220V, ngaloo ndlela imisela umsinga olinganisiweyo ofanelekileyo.

Qwalasela oku: i-1mm² i-copper core wire iyakwazi ukuthwala i-6A current, ilingana ne-6A*220V=1320W. Ngoko ke, izibane zombane ezingaphantsi kwe-1320W ziyahambelana ne-1mm² yocingo olusulungekileyo lobhedu.. Nangona kunjalo, ukunika ingxelo ngokuguga kocingo kunye nemiba yobushushu, ucingo oluyi-1.5mm² ludla ngokukhethwa.

Ngokwemigangatho ye-GB4706.1-1992/1998, inxenye yocingo lombane amaxabiso akhoyo ngoku alandelayo:

I-1mm² i-copper core wire ixhasa umthwalo wexesha elide we-6-8A.
I-1.5mm² i-copper core wire ixhasa umthwalo wexesha elide we-8-15A.
I-2.5mm² i-copper core wire ixhasa umthwalo wexesha elide we-16-25A.
I-4mm² i-copper core wire ixhasa umthwalo wexesha elide we-25-32A.
I-6mm² i-copper core wire ixhasa umthwalo wexesha elide we-32-40A.
