廢鐵廢銅回收公司認為電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)用于(yu)承(cheng)載電(dian)(dian)(dian)(dian)(dian)流的(de)(de)導(dao)電(dian)(dian)(dian)(dian)(dian)金屬線(xian)(xian)材。有實心的(de)(de)﹑絞合的(de)(de)或(huo)箔片編織的(de)(de)等各(ge)種(zhong)形式。按(an)絕(jue)緣(yuan)狀況分為裸電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)和(he)絕(jue)緣(yuan)電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)兩大類(lei)。電(dian)(dian)(dian)(dian)(dian)纜由一(yi)(yi)根或(huo)多根相互絕(jue)緣(yuan)的(de)(de)導(dao)電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)心置于(yu)密封護(hu)套中構成的(de)(de)絕(jue)緣(yuan)導(dao)線(xian)(xian)。其外可(ke)加(jia)保(bao)護(hu)覆蓋層，電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)與電(dian)(dian)(dian)(dian)(dian)纜的(de)(de)區別(bie)(bie)在(zai)于(yu)電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)的(de)(de)尺(chi)寸(cun)一(yi)(yi)般較小、結構較為簡單，但有時也將電(dian)(dian)(dian)(dian)(dian)纜歸入廣義(yi)的(de)(de)電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)之列。用途區別(bie)(bie)一(yi)(yi)裸電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)是不(bu)包(bao)任何絕(jue)緣(yuan)或(huo)保(bao)護(hu)層的(de)(de)電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)。

　　除作為傳輸(shu)電(dian)(dian)(dian)(dian)(dian)(dian)能和(he)信息(xi)的(de)(de)導(dao)線(xian)外，還可(ke)用(yong)(yong)(yong)于(yu)制造電(dian)(dian)(dian)(dian)(dian)(dian)機﹑電(dian)(dian)(dian)(dian)(dian)(dian)器的(de)(de)構件和(he)連接線(xian)。一般用(yong)(yong)(yong)銅、鋁、銅合(he)金(jin)、鋁合(he)金(jin)。此外，還有(you)各種(zhong)適用(yong)(yong)(yong)于(yu)特種(zhong)要(yao)(yao)求的(de)(de)絕(jue)緣電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)，如(ru)汽車用(yong)(yong)(yong)低壓電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)、汽車用(yong)(yong)(yong)高(gao)壓點火(huo)線(xian)、電(dian)(dian)(dian)(dian)(dian)(dian)機電(dian)(dian)(dian)(dian)(dian)(dian)器引接線(xian)、航空導(dao)線(xian)、補(bu)償導(dao)線(xian)等。電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)用(yong)(yong)(yong)于(yu)傳輸(shu)、分配電(dian)(dian)(dian)(dian)(dian)(dian)能或傳送(song)電(dian)(dian)(dian)(dian)(dian)(dian)信號。電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)按其用(yong)(yong)(yong)途可(ke)分為電(dian)(dian)(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)、通(tong)(tong)信電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)和(he)控制電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)等。結構區別一電(dian)(dian)(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)與普通(tong)(tong)電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)的(de)(de)差別主要(yao)(yao)是電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)尺寸較大，結構較復雜。電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)主要(yao)(yao)由以下4部(bu)分群組成(cheng)。導(dao)體：用(yong)(yong)(yong)高(gao)電(dian)(dian)(dian)(dian)(dian)(dian)導(dao)率(lv)材料制成(cheng)。絕(jue)緣層：用(yong)(yong)(yong)作電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)的(de)(de)絕(jue)緣材料應當具有(you)高(gao)的(de)(de)絕(jue)緣電(dian)(dian)(dian)(dian)(dian)(dian)阻，高(gao)的(de)(de)擊穿電(dian)(dian)(dian)(dian)(dian)(dian)場強度，低的(de)(de)介質(zhi)損耗和(he)低的(de)(de)介電(dian)(dian)(dian)(dian)(dian)(dian)常量。密封護套：保護絕(jue)緣線(xian)心(xin)免受機械、水分、潮氣、化學物(wu)品、光(guang)等的(de)(de)損傷。

　　1、具有優良的供電(dian)可靠性

　　（1）主干電纜導體無(wu)接(jie)頭，連(lian)續性(xing)好，減(jian)少了(le)故障點。

　　（2）預制(zhi)分支電纜接頭采用工廠(chang)全程機(ji)械化制(zhi)作，大大降低(di)了人為因素(su)造成質量(liang)不(bu)穩定現象(xiang)。

　　（3）分支接頭結構(gou)合理并引進日本先進工藝制作，接觸(chu)電阻極小，不(bu)受熱(re)脹冷縮影響。

　　（4）短(duan)時間完(wan)成分支接頭成型(xing)，避免了接頭處銅導(dao)體長時間暴露空氣中產(chan)生氧化而導(dao)致接觸電(dian)阻變化。

　　2、可明(ming)顯降低配電成本

　　與母線槽比，可降低工程(cheng)造價(jia)，并且技術(shu)經濟指標高，綜合經濟效益顯著。

　　3、品種(zhong)規(gui)格多，選用(yong)靈(ling)活，任意(yi)組合

　　（1）主干電纜從10 mm 2~630 mm 2,支線電纜從6 mm 2~400 mm 2任意組合。

　　（2）電(dian)纜的(de)品種較多，主要有FZ-VV、FZ-ZR-VV、FZ-NH-VV、FZ-YJV、FZ-ZR-YJV、FZ-NH-YJV、FZ-WL-ZR-YJE、FZ-DL-NH-YJV等，可根據(ju)需(xu)要選(xuan)用。

　　（3）分(fen)支接頭可(ke)根據樓(lou)層(ceng)需(xu)要(yao)任意設定分(fen)支位置。

　　4、安裝環境(jing)要求(qiu)低、施工方(fang)便

　　（1）占用(yong)(yong)建筑(zhu)面(mian)積小，有(you)利(li)于建筑(zhu)面(mian)積的(de)有(you)效使(shi)用(yong)(yong)，對土建的(de)空(kong)間尺寸(cun)要求(qiu)低(di)。

　　（2）使用環(huan)境要求(qiu)低(di)(di)，安裝精度要求(qiu)低(di)(di)。

　　（3）安裝(zhuang)(zhuang)簡單方(fang)便，安裝(zhuang)(zhuang)技(ji)術要求不(bu)高(gao)，安裝(zhuang)(zhuang)設備僅需一臺卷繞機即可(ke)，且安裝(zhuang)(zhuang)周(zhou)期短，僅為母線槽安裝(zhuang)(zhuang)工時的5%-10%，安裝(zhuang)(zhuang)勞動強度(du)低。

　　（4）由于電(dian)纜的彎曲(qu)半徑小，大大降(jiang)低了安裝難度，縮小了空間尺(chi)寸。

　　5、優(you)良(liang)的抗(kang)震性(xing)、氣密性(xing)、防(fang)水性(xing)和(he)耐火(huo)性(xing)

　　（1）優良的抗震(zhen)性，一般機械連接母線(xian)槽(cao)接頭(tou)，在墻體震(zhen)動(dong)后會發(fa)生接頭(tou)松(song)動(dong)，而預制(zhi)分支電(dian)纜則不會受到影響。特別(bie)是在通過(guo)建筑(zhu)沉降縫(feng)時不需要任何措施。
