聚酰亞an漆包線

聚(ju)酰亞an是目前有(you)機(ji)(ji)類漆(qi)(qi)(qi)包(bao)線(xian)中耐(nai)(nai)熱(re)等(deng)級zui高的(de)漆(qi)(qi)(qi)包(bao)線(xian)漆(qi)(qi)(qi)，其(qi)長期(qi)使(shi)(shi)用溫度可達220°C以上(shang)。該(gai)漆(qi)(qi)(qi)由美(mei)國(guo)于1958年研制(zhi)成(cheng)功。聚(ju)酰亞an漆(qi)(qi)(qi)包(bao)線(xian)具(ju)有(you)高的(de)耐(nai)(nai)熱(re)性，良好的(de)耐(nai)(nai)溶劑和耐(nai)(nai)冷凍劑性能。但(dan)由于成(cheng)本昂貴，漆(qi)(qi)(qi)包(bao)線(xian)設備，儲(chu)存(cun)穩定性差和具(ju)有(you)毒性，影響(xiang)了它的(de)廣泛使(shi)(shi)用。目前該(gai)漆(qi)(qi)(qi)包(bao)線(xian)使(shi)(shi)用某些特殊場合，如煤礦電機(ji)(ji)，宇宙空間儀器儀表等(deng)用線(xian)

漆(qi)包線(xian)是一(yi)(yi)種導線(xian)，酒精自粘漆(qi)包線(xian)，其表(biao)面涂有一(yi)(yi)層絕緣材料。它通常用(yong)于(yu)電(dian)(dian)(dian)(dian)機、電(dian)(dian)(dian)(dian)器和(he)儀(yi)表(biao)等(deng)工(gong)業設備中作為繞組(zu)(zu)線(xian)圈使(shi)用(yong)，起到電(dian)(dian)(dian)(dian)流(liu)的(de)傳輸與(yu)連接作用(yong)在電(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)子領域(yu)及(ji)高頻(pin)應(ying)用(yong)方(fang)面，使(shi)用(yong)的(de)是聚(ju)酯類（即“YJ”）耐高溫(wen)電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜，揚(yang)州漆(qi)包線(xian)，主要用(yong)在發電(dian)(dian)(dian)(dian)機組(zu)(zu)的(de)勵(li)磁系(xi)統中做電(dian)(dian)(dian)(dian)源線(xian)路(lu)和(he)控制電(dian)(dian)(dian)(dian)路(lu)。主要考(kao)慮性能參(can)數：長期工(gong)作溫(wen)度(du)應(ying)達(da)到180度(du)以(yi)上，短時(shi)間可承受250度(du)的(de)連續負荷；屏蔽性良好;具有一(yi)(yi)定(ding)(ding)的(de)耐磨特性以(yi)及(ji)低溫(wen)升等(deng)等(deng)特點(dian)都是他的(de)物理電(dian)(dian)(dian)(dian)氣性質(zhi)所決定(ding)(ding)的(de).

銅包鋁漆包線

銅(tong)(tong)(tong)(tong)包鋁(lv)漆(qi)包線(xian)是采用銅(tong)(tong)(tong)(tong)包鋁(lv)材料作內(nei)導(dao)體的新型電(dian)磁線(xian)，銅(tong)(tong)(tong)(tong)鋁(lv)漆(qi)包線(xian)哪家(jia)好，其特性(xing)介于銅(tong)(tong)(tong)(tong)鋁(lv)之(zhi)間，結合了銅(tong)(tong)(tong)(tong)的優良導(dao)電(dian)性(xing)和鋁(lv)的重量輕的優點.

銅包鋁漆包線的優點

重量輕

銅(tong)包鋁線密度是相(xiang)同線徑的純銅(tong)線的1/3.對降低電(dian)纜和線圈的重量十分有(you)效.

直流電阻率

銅包鋁線(xian)的直流(liu)電(dian)阻(zu)率約為(wei)純(chun)銅線(xian)的1.5倍;阻(zu)值(zhi)相同時，銅包鋁線(xian)重(zhong)量(liang)約為(wei)純(chun)銅線(xian)的1/2.

良好的釬焊性

銅(tong)(tong)包鋁(lv)由于其表面同心的包覆了一層純銅(tong)(tong)，因此具有跟純銅(tong)(tong)線(xian)一樣的可(ke)釬(han)焊性，而不必像鋁(lv)線(xian)那樣做特殊處(chu)理.
