漆(qi)包(bao)線小編談(tan)(tan)談(tan)(tan)實戰操(cao)作感想和(he)認知(zhi)

漆包(bao)線(xian)(xian)(xian)(xian)小編：在(zai)一臺正常(chang)運轉(zhuan)的(de)漆包(bao)機上，神(shen)州(zhou)漆包(bao)線(xian)(xian)(xian)(xian)廠家(jia)，操作人員的(de)精力和膂力大多數耗費在(zai)放(fang)線(xian)(xian)(xian)(xian)有些，互換放(fang)線(xian)(xian)(xian)(xian)盤使操作者支(zhi)付很大的(de)勞動力，換線(xian)(xian)(xian)(xian)時接頭(tou)易發作質量(liang)疑問(wen)及發作運轉(zhuan)毛病(bing)。有用的(de)辦法是大容量(liang)放(fang)線(xian)(xian)(xian)(xian)。

放(fang)(fang)(fang)線(xian)(xian)(xian)(xian)(xian)的關鍵是操控張(zhang)力，漆(qi)包線(xian)(xian)(xian)(xian)(xian)機器，張(zhang)力大時(shi)不(bu)只(zhi)拉(la)細導(dao)(dao)(dao)體(ti)，使導(dao)(dao)(dao)線(xian)(xian)(xian)(xian)(xian)外表失掉(diao)亮光，還影響漆(qi)包線(xian)(xian)(xian)(xian)(xian)的多項(xiang)功(gong)能(neng)。從外表上(shang)看，被拉(la)細的導(dao)(dao)(dao)線(xian)(xian)(xian)(xian)(xian)，涂(tu)制出的漆(qi)包線(xian)(xian)(xian)(xian)(xian)光澤較差；從功(gong)能(neng)來看，漆(qi)包線(xian)(xian)(xian)(xian)(xian)伸長(chang)率、回(hui)彈性、柔韌性、熱沖擊都受到影響。放(fang)(fang)(fang)線(xian)(xian)(xian)(xian)(xian)張(zhang)力太小，線(xian)(xian)(xian)(xian)(xian)容易(yi)跳(tiao)(tiao)動(dong)形(xing)成(cheng)并(bing)線(xian)(xian)(xian)(xian)(xian)、線(xian)(xian)(xian)(xian)(xian)碰(peng)爐(lu)口。放(fang)(fang)(fang)線(xian)(xian)(xian)(xian)(xian)時(shi)怕半圈(quan)張(zhang)力大，半圈(quan)張(zhang)力小，這(zhe)樣不(bu)只(zhi)使導(dao)(dao)(dao)線(xian)(xian)(xian)(xian)(xian)松亂、扎斷(duan)，一段一段被拉(la)細，而且(qie)還會(hui)導(dao)(dao)(dao)致烘爐(lu)內線(xian)(xian)(xian)(xian)(xian)的大跳(tiao)(tiao)動(dong)，形(xing)成(cheng)并(bing)線(xian)(xian)(xian)(xian)(xian)、碰(peng)線(xian)(xian)(xian)(xian)(xian)毛病。放(fang)(fang)(fang)線(xian)(xian)(xian)(xian)(xian)張(zhang)力要(yao)均(jun)勻恰(qia)當。

銅包鋁線

電(dian)纜按內導(dao)體(ti)的(de)不同(tong)來分，主(zhu)要有兩種，一(yi)(yi)種是純(chun)銅(tong)材料，一(yi)(yi)種是銅(tong)包鋁(lv)材料。銅(tong)包鋁(lv)的(de)英(ying)文(wen)是：Copper Clad

Aluminum，所以銅(tong)(tong)包(bao)(bao)鋁(lv)導體也常稱為：CCA導體。銅(tong)(tong)包(bao)(bao)鋁(lv)復合線(xian)(xian)材早由德國(guo)(guo)在(zai)(zai)上個世紀30年(nian)代推出，隨(sui)后在(zai)(zai)英國(guo)(guo)、美國(guo)(guo)、法國(guo)(guo)等國(guo)(guo)得以推廣，漆包(bao)(bao)線(xian)(xian)機器廠(chang)家，廣泛應用(yong)(yong)于各(ge)個領域(yu)。美國(guo)(guo)的CATV電纜早在(zai)(zai)1968年(nian)就開始試(shi)用(yong)(yong)銅(tong)(tong)包(bao)(bao)鋁(lv)線(xian)(xian)，消耗數量(liang)達(da)3萬噸(dun)/年(nian)。現在(zai)(zai)美洲國(guo)(guo)家已經用(yong)(yong)銅(tong)(tong)包(bao)(bao)鋁(lv)(鋼)電纜代替了(le)純銅(tong)(tong)電纜。近(jin)年(nian)來，我(wo)國(guo)(guo)銅(tong)(tong)包(bao)(bao)鋁(lv)CATV電纜也開始被(bei)大(da)(da)量(liang)使用(yong)(yong)。國(guo)(guo)家于2000年(nian)制定了(le)行業標準--SJ/T11223-2000，大(da)(da)力推廣宣傳使用(yong)(yong)銅(tong)(tong)包(bao)(bao)鋁(lv)電纜。目前上海、廣州、浙江、遼寧(ning)等地的有線(xian)(xian)已經普(pu)遍采(cai)用(yong)(yong)了(le)銅(tong)(tong)包(bao)(bao)鋁(lv)電纜，反應良好。

銅(tong)包(bao)鋁(lv)是在鋁(lv)或鋁(lv)/鋼(gang)合金芯材(cai)表面同心包(bao)覆銅(tong)層，經(jing)拉拔而成，銅(tong)層厚度(du)在0.55mm以上(shang)(shang)。由于高頻信(xin)號在導(dao)體(ti)上(shang)(shang)傳(chuan)輸具有(you)趨膚效應的特點(dian)，有(you)線電是信(xin)號在0.008mm以上(shang)(shang)的銅(tong)層表面傳(chuan)遞，銅(tong)包(bao)鋁(lv)內導(dao)體(ti)能完全滿足信(xin)號傳(chuan)輸要求，其信(xin)號的傳(chuan)輸特性與相同直徑線銅(tong)體(ti)相一(yi)致。

銅包鋁電纜定義：

銅(tong)包(bao)鋁電(dian)(dian)纜(lan)是指以鋁芯線(xian)(xian)代替銅(tong)成(cheng)為電(dian)(dian)纜(lan)主(zhu)體(ti)，漆包(bao)線(xian)(xian)，外(wai)面包(bao)一(yi)定比例(li)的(de)(de)銅(tong)層的(de)(de)電(dian)(dian)線(xian)(xian)電(dian)(dian)纜(lan)。對(dui)于(yu)機電(dian)(dian)安裝行業(ye)，電(dian)(dian)線(xian)(xian)電(dian)(dian)纜(lan)在機電(dian)(dian)安裝工(gong)程中占(zhan)據了(le)(le)重要的(de)(de)地(di)位，作(zuo)為其主(zhu)要原材料的(de)(de)銅(tong)，占(zhan)了(le)(le)電(dian)(dian)纜(lan)產品總(zong)成(cheng)本的(de)(de)70%~80%，銅(tong)電(dian)(dian)纜(lan)的(de)(de)價(jia)格隨著(zhu)銅(tong)價(jia)的(de)(de)上漲而(er)急劇增長，對(dui)投資方(fang)和施工(gong)方(fang)在工(gong)程造(zao)價(jia)控(kong)制方(fang)面帶來極(ji)大的(de)(de)困(kun)難(nan)，為此，銅(tong)包(bao)鋁電(dian)(dian)纜(lan)研究和應用迅速(su)增長。
