1.Daim ntawv thov
Lub tsev hluav taws xob xaim tuaj yeem siv rau tooj liab (aluminium)-core cables nyob rau hauv qhov ntsuas A / C voltage ntawm 450/750V thiab lub zog hauv qab no, teeb pom kev zoo, cov khoom siv hluav taws xob niaj hnub, cov cuab yeej thiab cov khoom siv sib txuas lus. Tshwj xeeb yog tsim rau cov hluav taws xob circuits sab hauv tsev lossis sab nraum zoov.
2.Cov yam ntxwv ua haujlwm
1) U0/U yog 450/750V thiab 300/500V;
2) Qhov kev tso cai ua haujlwm ntev ntawm cov hlau yuav tsum tsis pub tshaj 7 0 degree C; Lub cable (xaim) yuav tsum tau muab tso rau ntawm qhov kub tsis qis dua 0 ° C;
3) Lub vojvoog dabtsi yog khoov yuav tsum tsis pub tsawg dua 4D ntawm txoj kab uas hla tag nrho nws tsawg dua 25 hli; Lub vojvoog dabtsi yog khoov yuav tsum tsis pub tsawg dua 6D ntawm txoj kab uas hla tag nrho thaum nws ntau dua 25 hli.
