Copper electrical conductivity hi silver hnuaiah a awm a, 20 degree-ah 58.5 MS/m (meter khatah Siemens maktaduai) a tling thei a ni. He characteristic hian high-voltage leh high-current scenario tan chuan duhthlanna duh ber a siam a ni. Chumi danglamna chu aluminum electrical conductivity chu 37.7 MS/m vel a ni a, hei hi copper aiin 64.5% chauh a ni. Cross-sectional area ang chiah hnuaiah hian tuna aluminum busbar-te hian tuna-carrying capacity chu copper busbar-te aiin 30% velin a hniam zawk a ni. Electrical conductivity inang chiah neih theih nan aluminium busbar cross-sectional area tihpun a ngai a, chu chuan volume leh weight a tisang a ni.
Mahse, copper density sang (8.96g/cm3) hian harsatna a thlen bawk. Design rit lo mamawhna scenario-ah chuan aluminium bar (density 2.7g/cm3 nei) te hian an cross-sectional area tihpun hmangin copper bar aiin total weight hniam zawk an la hmu thei tho a ni. Entirnan, energy thar lirthei siamna atana battery pack inzawmkhawmnaah chuan aluminium bar hi a rit lutuk avangin hman a ni nasa hle a, mahse an corrosion resistance tihpun nan surface oxidation treatment a ngai a ni.
