電(dian)(dian)纜(lan)(lan)(lan)線(xian)(xian)起到疏導電(dian)(dian)流(liu)(liu)的(de)(de)作用(yong)。 電(dian)(dian)流(liu)(liu)的(de)(de)強弱和使(shi)用(yong)環境的(de)(de)不(bu)同電(dian)(dian)纜(lan)(lan)(lan)線(xian)(xian)結構也不(bu)相同，常見的(de)(de)電(dian)(dian)纜(lan)(lan)(lan)線(xian)(xian)有(you)銅芯(xin)線(xian)(xian)和鋁(lv)(lv)芯(xin)線(xian)(xian)兩種。使(shi)用(yong)久后電(dian)(dian)纜(lan)(lan)(lan)線(xian)(xian)會發生硬化等不(bu)安全(quan)事故(gu)，機器所需(xu)的(de)(de)電(dian)(dian)流(liu)(liu)增加或電(dian)(dian)纜(lan)(lan)(lan)線(xian)(xian)到一(yi)定(ding)年限必(bi)須更換電(dian)(dian)纜(lan)(lan)(lan)線(xian)(xian)。換下來的(de)(de)電(dian)(dian)纜(lan)(lan)(lan)線(xian)(xian)可(ke)以再(zai)(zai)分(fen)解(jie)利(li)用(yong)。 　　電(dian)(dian)纜(lan)(lan)(lan)線(xian)(xian)拆解(jie)程序相對簡(jian)單。　　1：首先是把(ba)鋁(lv)(lv)芯(xin)線(xian)(xian)和銅芯(xin)線(xian)(xian)，大小電(dian)(dian)纜(lan)(lan)(lan)線(xian)(xian)分(fen)開　　2：外面(mian)有(you)鐵皮或鐵絲(si)(si)包著(zhu)的(de)(de)電(dian)(dian)纜(lan)(lan)(lan)線(xian)(xian)先把(ba)鐵皮或鐵絲(si)(si)撥(bo)去　　3：用(yong)專撥(bo)電(dian)(dian)線(xian)(xian)的(de)(de)撥(bo)線(xian)(xian)機把(ba)外面(mian)的(de)(de)皮撥(bo)離　　撥(bo)出(chu)來的(de)(de)鋁(lv)(lv)和銅分(fen)別再(zai)(zai)鑄(zhu)造成鋁(lv)(lv)定(ding)、銅定(ding)和其他產品、塑料皮再(zai)(zai)從新造粒。
