D銅=(ρ銅/ρ鋁)1/2 *D鋁

D銅:銅線直徑

D鋁:鋁線直徑

ρ鋁:鋁的電阻(zu)率，取1/35.5

ρ銅:銅的電阻(zu)率，取1/58

注：公(gong)式中1/2是(shi)指開平方，銅(tong)漆(qi)包線(xian)批發，而(er)不是(shi)乘。

如：使用(yong)0.51㎜的(de)鋁漆(qi)包線(xian)，改為使用(yong)銅(tong)線(xian)時，銅(tong)線(xian)的(de)線(xian)徑為D銅(tong)=(35.5/58)1/2*0.51=0.6121 1/2*0.51=0.7823*0.51=0.4 。即(ji)0.51㎜鋁漆(qi)包線(xian)改為銅(tong)漆(qi)包線(xian)后(hou)需(xu)用(yong)0.40㎜銅(tong)線(xian)代替。

鋁線電機換銅線的注意事項

取原來(lai)(lai)鋁線截(jie)面(mian)積(ji)的(de)80%，就是(shi)代替后銅線的(de)截(jie)面(mian)積(ji)，按(an)原來(lai)(lai)數據嵌線；或(huo)者繞組(zu)的(de)匝數按(an)原數據；銅線線徑可按(an)鋁線線徑的(de)80%或(huo)原線徑即(ji)可

銅包鋁漆包線

銅(tong)包(bao)(bao)鋁(lv)(lv)漆包(bao)(bao)線(xian)是采用(yong)銅(tong)包(bao)(bao)鋁(lv)(lv)材料(liao)作內導(dao)體(ti)的(de)(de)新型電磁(ci)線(xian)，其特性介于(yu)銅(tong)鋁(lv)(lv)之間，銅(tong)漆包(bao)(bao)線(xian)生產(chan)廠家(jia)，結合了銅(tong)的(de)(de)優(you)良導(dao)電性和鋁(lv)(lv)的(de)(de)重量輕(qing)的(de)(de)優(you)點.

銅包鋁漆包線的優點

重量輕

銅(tong)包(bao)鋁線(xian)密度是(shi)相同線(xian)徑的純銅(tong)線(xian)的1/3.對降低電纜(lan)和線(xian)圈的重量十分有效.

直流電阻率

銅包鋁線(xian)的(de)直流電阻(zu)率約(yue)(yue)為純銅線(xian)的(de)1.5倍;阻(zu)值相同時(shi)，銅包鋁線(xian)重量(liang)約(yue)(yue)為純銅線(xian)的(de)1/2.

良好的釬焊性

銅(tong)包(bao)鋁由(you)于其表面同心的包(bao)覆了一層(ceng)純銅(tong)，因此(ci)具有(you)跟純銅(tong)線一樣(yang)的可釬焊性(xing)，而不必像鋁線那樣(yang)做特殊處(chu)理.
