漆包線

在(zai)(zai)退火爐前(qian)裝置(zhi)助(zhu)力(li)(li)輪對張(zhang)(zhang)(zhang)力(li)(li)的操(cao)控有(you)很大協助(zhu)。軟銅線(xian)在(zai)(zai)室溫下其(qi)醉大不(bu)(bu)延伸(shen)(shen)張(zhang)(zhang)(zhang)力(li)(li)約為15kg/mm2，在(zai)(zai)400℃下醉大不(bu)(bu)延伸(shen)(shen)張(zhang)(zhang)(zhang)力(li)(li)約為7kg/mm2；在(zai)(zai)460℃下醉大不(bu)(bu)延伸(shen)(shen)張(zhang)(zhang)(zhang)力(li)(li)為4kg/mm2；在(zai)(zai)500℃下醉大不(bu)(bu)延伸(shen)(shen)張(zhang)(zhang)(zhang)力(li)(li)為2kg/mm2。在(zai)(zai)正常的漆(qi)(qi)包線(xian)涂制過程中，漆(qi)(qi)包線(xian)的張(zhang)(zhang)(zhang)力(li)(li)要顯著小于不(bu)(bu)延伸(shen)(shen)張(zhang)(zhang)(zhang)力(li)(li)，鎮(zhen)江鋁漆(qi)(qi)包線(xian)，需(xu)求操(cao)控在(zai)(zai)50%擺(bai)布，放線(xian)張(zhang)(zhang)(zhang)力(li)(li)操(cao)控在(zai)(zai)不(bu)(bu)延伸(shen)(shen)張(zhang)(zhang)(zhang)力(li)(li)的20%擺(bai)布。

大(da)標(biao)準大(da)容量線(xian)軸(zhou)通常選用(yong)(yong)徑向旋(xuan)轉式放線(xian)器(qi)；中等(deng)標(biao)準導線(xian)通常選用(yong)(yong)越端(duan)式或(huo)毛刷(shua)(shua)式放線(xian)器(qi)；微細標(biao)準導線(xian)通常選用(yong)(yong)毛刷(shua)(shua)式或(huo)雙錐套式放線(xian)器(qi)。

不論選用哪種放(fang)線方法，都對裸銅線線軸的布(bu)局(ju)和質量有嚴格需求

----外表應(ying)光(guang)亮以確保(bao)線材不被擦傷

----軸芯兩邊及側板內外有2—4mm半徑的r角(jiao)以確保放線過程(cheng)中(zhong)能均衡放出

----線軸加工完(wan)后，必須作動、靜平衡試驗(yan)

----毛刷放線(xian)器需求軸芯直徑：側板直徑小于1：1.7；越端(duan)放線(xian)需求小于1：1.9，不然(ran)放線(xian)至軸芯時會(hui)呈現斷線(xian)表象

銅包(bao)(bao)(bao)(bao)鋁(lv)(lv)線(xian)(xian)(xian)(xian)是一種常(chang)見的(de)(de)(de)(de)電(dian)(dian)線(xian)(xian)(xian)(xian)電(dian)(dian)纜產品，具有良好的(de)(de)(de)(de)導(dao)電(dian)(dian)性能(neng)和(he)耐磨性能(neng)。以(yi)下是銅包(bao)(bao)(bao)(bao)鋁(lv)(lv)線(xian)(xian)(xian)(xian)的(de)(de)(de)(de)使(shi)(shi)用方法：確(que)定(ding)(ding)用途：首先(xian)需(xu)要(yao)確(que)定(ding)(ding)銅包(bao)(bao)(bao)(bao)鋁(lv)(lv)線(xian)(xian)(xian)(xian)的(de)(de)(de)(de)用途，例(li)如用于電(dian)(dian)力傳輸、電(dian)(dian)器連(lian)接(jie)(jie)等(deng)(deng)(deng)。選擇規(gui)(gui)格：根據用途和(he)負載要(yao)求，選擇合適(shi)的(de)(de)(de)(de)銅包(bao)(bao)(bao)(bao)鋁(lv)(lv)線(xian)(xian)(xian)(xian)規(gui)(gui)格。銅包(bao)(bao)(bao)(bao)鋁(lv)(lv)線(xian)(xian)(xian)(xian)的(de)(de)(de)(de)規(gui)(gui)格一般以(yi)導(dao)體的(de)(de)(de)(de)截面(mian)積表示(shi)，例(li)如1平方毫(hao)(hao)米(mi)、2平方毫(hao)(hao)米(mi)等(deng)(deng)(deng)。安(an)(an)(an)(an)裝(zhuang)(zhuang)敷(fu)設：銅包(bao)(bao)(bao)(bao)鋁(lv)(lv)線(xian)(xian)(xian)(xian)的(de)(de)(de)(de)安(an)(an)(an)(an)裝(zhuang)(zhuang)敷(fu)設應符(fu)合相(xiang)關(guan)(guan)的(de)(de)(de)(de)安(an)(an)(an)(an)全(quan)規(gui)(gui)定(ding)(ding)和(he)技術(shu)要(yao)求。在(zai)安(an)(an)(an)(an)裝(zhuang)(zhuang)敷(fu)設時，應注意(yi)(yi)保(bao)護(hu)線(xian)(xian)(xian)(xian)纜，避免受潮(chao)、磨損等(deng)(deng)(deng)問題。連(lian)接(jie)(jie)接(jie)(jie)頭(tou)：銅包(bao)(bao)(bao)(bao)鋁(lv)(lv)線(xian)(xian)(xian)(xian)的(de)(de)(de)(de)連(lian)接(jie)(jie)接(jie)(jie)頭(tou)應符(fu)合相(xiang)關(guan)(guan)的(de)(de)(de)(de)安(an)(an)(an)(an)全(quan)規(gui)(gui)定(ding)(ding)和(he)技術(shu)要(yao)求。在(zai)連(lian)接(jie)(jie)接(jie)(jie)頭(tou)時，應注意(yi)(yi)清潔線(xian)(xian)(xian)(xian)纜端(duan)頭(tou)，確(que)保(bao)接(jie)(jie)觸良好，避免接(jie)(jie)頭(tou)發熱、短路等(deng)(deng)(deng)問題。維護(hu)檢查(cha)：銅包(bao)(bao)(bao)(bao)鋁(lv)(lv)線(xian)(xian)(xian)(xian)在(zai)使(shi)(shi)用過程中(zhong)，應定(ding)(ding)期(qi)進行(xing)維護(hu)檢查(cha)，檢查(cha)線(xian)(xian)(xian)(xian)纜的(de)(de)(de)(de)磨損、老化、接(jie)(jie)頭(tou)等(deng)(deng)(deng)問題，及時進行(xing)維修或(huo)更(geng)換。總之，銅包(bao)(bao)(bao)(bao)鋁(lv)(lv)線(xian)(xian)(xian)(xian)的(de)(de)(de)(de)使(shi)(shi)用需(xu)要(yao)注意(yi)(yi)確(que)定(ding)(ding)用途、選擇規(gui)(gui)格、安(an)(an)(an)(an)裝(zhuang)(zhuang)敷(fu)設、連(lian)接(jie)(jie)接(jie)(jie)頭(tou)和(he)維護(hu)檢查(cha)等(deng)(deng)(deng)方面(mian)，以(yi)確(que)保(bao)其正常(chang)使(shi)(shi)用和(he)安(an)(an)(an)(an)全(quan)性能(neng)。

銅包(bao)鋁(lv)線(xian)是指以(yi)鋁(lv)芯線(xian)為主體，外面(mian)鍍一定(ding)比例的銅層的電(dian)線(xian)，可(ke)以(yi)用作同軸電(dian)纜(lan)用導體及電(dian)氣裝備(bei)中電(dian)線(xian)電(dian)纜(lan)導體。鋁(lv)線(xian)比重小(xiao)，但(dan)其焊接性(xing)能(neng)(neng)不好，鋁(lv)漆包(bao)線(xian)廠(chang)家，故在鋁(lv)線(xian)外包(bao)銅層，鋁(lv)漆包(bao)線(xian)哪家好，這種銅包(bao)鋁(lv)線(xian)既(ji)可(ke)利(li)用鋁(lv)比重小(xiao)的優點，也可(ke)改善(shan)焊接性(xing)能(neng)(neng)。 ?適用于電(dian)力(li)、電(dian)器行(xing)業，類別等級為國際、國內。

主要功能

因為該種電(dian)線的主(zhu)要功能(neng)是(shi)傳輸信號(hao)，鋁漆包線價(jia)格，其流(liu)過(guo)的電(dian)流(liu)很(hen)小。但是(shi)，由于鋁的導電(dian)率只有銅(tong)(tong)(tong)的2/3，所以(yi)國家biaozhun規定凡是(shi)用作(zuo)傳輸電(dian)能(neng)的電(dian)線電(dian)纜必(bi)須用不(bu)鍍金屬或(huo)鍍金屬的退火(huo)銅(tong)(tong)(tong)線作(zuo)導體(ti)，禁(jin)止用鋁線（包括(kuo)銅(tong)(tong)(tong)包鋁線）作(zuo)導體(ti)。
