銅(tong)排(pai):又叫銅(tong)母排(pai)或銅(tong)匯流排(pai),是由銅(tong)材(cai)質(zhi)制(zhi)作的(de),截面為矩(ju)形(xing)或倒(dao)角(jiao)(圓(yuan)角(jiao))矩(ju)形(xing)的(de)長導體,由鋁(lv)(lv)質(zhi)材(cai)料制(zhi)作的(de)稱為鋁(lv)(lv)排(pai),在(zai)電路中起輸送電流和(he)連接電氣設備的(de)作用. 由于銅(tong)的(de)導電性(xing)能等優于鋁(lv)(lv),銅(tong)排(pai)在(zai)電氣設備,

銅排(pai)(pai)作用(yong)：廣泛應(ying)用(yong)在成套配電(dian)裝置中(zhong)(zhong)，如配電(dian)柜(ju)，電(dian)池包正負(fu)極連(lian)接;一(yi)般(ban)(ban)在配電(dian)柜(ju)中(zhong)(zhong)的U、V、W相(xiang)(xiang)(xiang)母排(pai)(pai)和PE母排(pai)(pai)均(jun)采用(yong)銅排(pai)(pai);銅排(pai)(pai)在使用(yong)中(zhong)(zhong)一(yi)般(ban)(ban)標有(you)(you)相(xiang)(xiang)(xiang)色(se)字母標志或涂(tu)(tu)有(you)(you)相(xiang)(xiang)(xiang)色(se)漆,U相(xiang)(xiang)(xiang)銅排(pai)(pai)涂(tu)(tu)有(you)(you)黃色(se),V相(xiang)(xiang)(xiang)銅排(pai)(pai)涂(tu)(tu)有(you)(you)綠色(se),W相(xiang)(xiang)(xiang)銅排(pai)(pai)涂(tu)(tu)有(you)(you)紅色(se),PE母線銅排(pai)(pai)涂(tu)(tu)有(you)(you)黃綠相(xiang)(xiang)(xiang)間雙(shuang)色(se).
