聚酰胺酰亞an漆

聚酰胺酰亞an漆(qi)(qi)(qi)是(shi)目(mu)前(qian)漆(qi)(qi)(qi)包(bao)(bao)(bao)(bao)線漆(qi)(qi)(qi)中性(xing)能較全mian，具有(you)高的耐熱(re)性(xing)、機械性(xing)能、耐冷凍(dong)劑性(xing)能和(he)耐化學性(xing)能，因(yin)此(ci)有(you)漆(qi)(qi)(qi)包(bao)(bao)(bao)(bao)線漆(qi)(qi)(qi)之wang的美稱。該漆(qi)(qi)(qi)目(mu)前(qian)主要應用(yong)其獨te的性(xing)能，廣(guang)泛用(yong)作復合涂層漆(qi)(qi)(qi)包(bao)(bao)(bao)(bao)線的面漆(qi)(qi)(qi)，鹽城鋁漆(qi)(qi)(qi)包(bao)(bao)(bao)(bao)線，提高復合線的耐熱(re)性(xing)和(he)降低(di)成本。目(mu)前(qian)國(guo)內(nei)主要是(shi)用(yong)其涂制耐冷凍(dong)劑漆(qi)(qi)(qi)包(bao)(bao)(bao)(bao)線，鋁漆(qi)(qi)(qi)包(bao)(bao)(bao)(bao)線哪(na)家好，此(ci)漆(qi)(qi)(qi)國(guo)內(nei)少量(liang)生產(chan)，主要從美國(guo)，意大利和(he)德國(guo)進口

銅包鋁漆包線

銅(tong)(tong)包鋁漆包線(xian)是采(cai)用銅(tong)(tong)包鋁材料作內導(dao)體的(de)新(xin)型電(dian)磁線(xian)，其特(te)性介于銅(tong)(tong)鋁之間，結合了(le)銅(tong)(tong)的(de)優良導(dao)電(dian)性和鋁的(de)重量輕的(de)優點.

銅包鋁漆包線的優點

重量輕

銅(tong)包鋁線(xian)密度是相同線(xian)徑的純銅(tong)線(xian)的1/3.對降低(di)電(dian)纜(lan)和線(xian)圈的重(zhong)量十分有效.

直流電阻率

銅(tong)包鋁(lv)線(xian)(xian)的直流(liu)電阻率約(yue)(yue)為純(chun)(chun)銅(tong)線(xian)(xian)的1.5倍;阻值相同(tong)時，銅(tong)包鋁(lv)線(xian)(xian)重量約(yue)(yue)為純(chun)(chun)銅(tong)線(xian)(xian)的1/2.

良好的釬焊性

銅包(bao)鋁(lv)由(you)于其表面同心(xin)的包(bao)覆(fu)了一層純(chun)銅，因此(ci)具(ju)有跟純(chun)銅線(xian)一樣的可釬(han)焊性，鋁(lv)漆包(bao)線(xian)生產廠家，而(er)不必像鋁(lv)線(xian)那樣做特殊處理.

D銅(tong)=(ρ銅(tong)/ρ鋁)1/2 *D鋁

D銅:銅線直徑

D鋁:鋁線直徑

ρ鋁(lv):鋁(lv)的電阻(zu)率(lv)，取(qu)1/35.5

ρ銅(tong):銅(tong)的電阻率，取1/58

注：公式中1/2是指開(kai)平(ping)方，而不是乘(cheng)。

如：使(shi)用0.51㎜的(de)鋁(lv)漆包(bao)線(xian)(xian)，改(gai)(gai)為使(shi)用銅(tong)線(xian)(xian)時，銅(tong)線(xian)(xian)的(de)線(xian)(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(lv)漆包(bao)線(xian)(xian)改(gai)(gai)為銅(tong)漆包(bao)線(xian)(xian)后需(xu)用0.40㎜銅(tong)線(xian)(xian)代替。

鋁線電(dian)機換銅線的注(zhu)意事項

取原(yuan)(yuan)來(lai)鋁線截面積的(de)(de)(de)80%，就是代替后銅(tong)線的(de)(de)(de)截面積，按(an)原(yuan)(yuan)來(lai)數據(ju)嵌線；或者(zhe)繞組的(de)(de)(de)匝(za)數按(an)原(yuan)(yuan)數據(ju)；銅(tong)線線徑(jing)可按(an)鋁線線徑(jing)的(de)(de)(de)80%或原(yuan)(yuan)線徑(jing)即(ji)可
