銅(tong)(tong)(tong)排:又叫銅(tong)(tong)(tong)母排或(huo)(huo)銅(tong)(tong)(tong)匯流(liu)(liu)排,是由銅(tong)(tong)(tong)材質制(zhi)作的(de)(de)(de),截面為矩形(xing)或(huo)(huo)倒(dao)角(圓角)矩形(xing)的(de)(de)(de)長導體,由鋁(lv)(lv)質材料制(zhi)作的(de)(de)(de)稱為鋁(lv)(lv)排,在電(dian)路中起輸(shu)送(song)電(dian)流(liu)(liu)和(he)連(lian)接電(dian)氣設備的(de)(de)(de)作用. 由于(yu)銅(tong)(tong)(tong)的(de)(de)(de)導電(dian)性能等優(you)于(yu)鋁(lv)(lv),銅(tong)(tong)(tong)排在電(dian)氣設備,

銅(tong)排(pai)(pai)(pai)作用：廣泛應(ying)用在成套配(pei)電裝置中(zhong)，如(ru)配(pei)電柜(ju)，電池包正負極連(lian)接;一般在配(pei)電柜(ju)中(zhong)的(de)U、V、W相母排(pai)(pai)(pai)和(he)PE母排(pai)(pai)(pai)均采用銅(tong)排(pai)(pai)(pai);銅(tong)排(pai)(pai)(pai)在使用中(zhong)一般標有(you)相色(se)(se)字母標志或涂(tu)有(you)相色(se)(se)漆,U相銅(tong)排(pai)(pai)(pai)涂(tu)有(you)黃色(se)(se),V相銅(tong)排(pai)(pai)(pai)涂(tu)有(you)綠色(se)(se),W相銅(tong)排(pai)(pai)(pai)涂(tu)有(you)紅色(se)(se),PE母線銅(tong)排(pai)(pai)(pai)涂(tu)有(you)黃綠相間雙色(se)(se).
