公司(si)主打(da)漆(qi)包線(xian)型號有(you)（155，180級）聚氨酯（QA/UEW）、(130，155級)聚酯（QZ/PEW）等及各(ge)類自(zi)粘性銅包鋁漆(qi)包線(xian)。

銅(tong)包(bao)鋁線(xian)(xian)是一種新型(xing)的(de)導線(xian)(xian)材料，銅(tong)包(bao)鋁繞(rao)組(zu)線(xian)(xian)，主要(yao)用來取代全系列純鋁合金(jin)線(xian)(xian)和(he)電(dian)(dian)(dian)纜。它的(de)導電(dian)(dian)(dian)性能優良且成(cheng)本相對(dui)較低(di)，適合用于各種連接(jie)線(xian)(xian)路和(he)電(dian)(dian)(dian)力(li)輸送等重要(yao)場合.在一些特殊(shu)情況下（如、臺風(feng)），或受損但未斷開的(de)電(dian)(dian)(dian)線(xian)(xian)可能會(hui)造成(cheng)觸點短(duan)路或者因接(jie)觸不(bu)良導致(zhi)電(dian)(dian)(dian)阻過大產生高溫(wen)燒毀(hui)等問題發生時它可以起到(dao)保護(hu)電(dian)(dian)(dian)路板安全的(de)作用；同時它還可以降低(di)布線(xian)(xian)的(de)安裝難度(du)從而提(ti)高整個(ge)系統的(de)穩定性和(he)工作效率。（注意：當(dang)外界溫(wen)度(du)過低(di)或缺水的(de)時候不(bu)建議(yi)使用。）

銅(tong)(tong)(tong)(tong)包鋁(lv)導體(ti)是按重(zhong)量出售(shou)的(de)(de)，純(chun)銅(tong)(tong)(tong)(tong)導體(ti)也是按重(zhong)量出售(shou)的(de)(de)，銅(tong)(tong)(tong)(tong)包鋁(lv)導體(ti)的(de)(de)價(jia)格(ge)要比相同(tong)重(zhong)量的(de)(de)純(chun)銅(tong)(tong)(tong)(tong)導體(ti)貴一些。但是同(tong)樣重(zhong)量的(de)(de)銅(tong)(tong)(tong)(tong)包鋁(lv)要比純(chun)銅(tong)(tong)(tong)(tong)導體(ti)長度長很(hen)多，神州(zhou)銅(tong)(tong)(tong)(tong)包鋁(lv)，而電(dian)纜是按長度計算的(de)(de)。相同(tong)重(zhong)量銅(tong)(tong)(tong)(tong)包鋁(lv)線是銅(tong)(tong)(tong)(tong)線長度的(de)(de)2.5倍，價(jia)格(ge)僅(jin)僅(jin)是每(mei)噸(dun)多幾百元。綜合(he)下(xia)來，銅(tong)(tong)(tong)(tong)包鋁(lv)就很(hen)有優(you)勢。由(you)于銅(tong)(tong)(tong)(tong)包鋁(lv)電(dian)纜比較輕，電(dian)纜的(de)(de)運輸成本(ben)、安裝架(jia)設成本(ben)都會有所降(jiang)低，會給施工(gong)帶來一定的(de)(de)方便(bian)性。

直流(liu)(liu)(liu)電(dian)(dian)阻率。銅(tong)包(bao)(bao)(bao)鋁(lv)(lv)線(xian)(xian)的(de)(de)(de)(de)電(dian)(dian)阻率比純銅(tong)線(xian)(xian)大，約(yue)(yue)為純銅(tong)線(xian)(xian)的(de)(de)(de)(de)1.5倍，在陰值相(xiang)同時，銅(tong)包(bao)(bao)(bao)鋁(lv)(lv)線(xian)(xian)重量約(yue)(yue)為純銅(tong)線(xian)(xian)的(de)(de)(de)(de)1/2。根據集膚(fu)效(xiao)(xiao)應(ying)(ying)計算，在5MHz以上高(gao)頻時，銅(tong)包(bao)(bao)(bao)鋁(lv)(lv)電(dian)(dian)磁(ci)線(xian)(xian)，與相(xiang)同截面的(de)(de)(de)(de)銅(tong)導體(ti)(ti)相(xiang)比，其電(dian)(dian)阻率相(xiang)等。在50Hz頻率的(de)(de)(de)(de)電(dian)(dian)力電(dian)(dian)纜(lan)的(de)(de)(de)(de)使(shi)用中，其銅(tong)導體(ti)(ti)的(de)(de)(de)(de)集膚(fu)效(xiao)(xiao)應(ying)(ying)和(he)鄰近效(xiao)(xiao)應(ying)(ying)在150mm2以上就逐漸顯得突出，同時由于科學(xue)技術的(de)(de)(de)(de)不斷發展(zhan)，產(chan)生(sheng)(sheng)高(gao)次(ci)諧波(bo)(bo)(bo)電(dian)(dian)流(liu)(liu)(liu)和(he)能源會注入(ru)到(dao)供電(dian)(dian)系(xi)統中，銅(tong)包(bao)(bao)(bao)鋁(lv)(lv)，在系(xi)統的(de)(de)(de)(de)阻抗(kang)上產(chan)生(sheng)(sheng)出相(xiang)應(ying)(ying)頻率的(de)(de)(de)(de)高(gao)次(ci)諧波(bo)(bo)(bo)電(dian)(dian)壓(ya)，致(zhi)使(shi)電(dian)(dian)壓(ya)的(de)(de)(de)(de)波(bo)(bo)(bo)形發生(sheng)(sheng)畸變，增加(jia)供電(dian)(dian)系(xi)統的(de)(de)(de)(de)損耗(hao)，使(shi)導體(ti)(ti)發熱增加(jia)；此外(wai)，電(dian)(dian)纜(lan)使(shi)諧波(bo)(bo)(bo)放大，在接頭(tou)處產(chan)生(sheng)(sheng)過電(dian)(dian)壓(ya)而(er)損壞電(dian)(dian)纜(lan)頭(tou)。采用銅(tong)包(bao)(bao)(bao)鋁(lv)(lv)導體(ti)(ti)會起(qi)到(dao)降低高(gao)次(ci)諧波(bo)(bo)(bo)產(chan)生(sheng)(sheng)的(de)(de)(de)(de)交流(liu)(liu)(liu)阻抗(kang)（電(dian)(dian)阻）的(de)(de)(de)(de)作用。在其他使(shi)用場合，通過采取提高(gao)銅(tong)包(bao)(bao)(bao)鋁(lv)(lv)單絲中銅(tong)的(de)(de)(de)(de)體(ti)(ti)積和(he)相(xiang)應(ying)(ying)的(de)(de)(de)(de)工藝措施，使(shi)銅(tong)包(bao)(bao)(bao)鋁(lv)(lv)/銅(tong)復合導體(ti)(ti)在現有同規(gui)格導體(ti)(ti)的(de)(de)(de)(de)外(wai)徑尺寸(cun)上限內，滿足導體(ti)(ti)直流(liu)(liu)(liu)電(dian)(dian)阻要求。
