柔性拖(tuo)鏈電(dian)纜(lan)(lan)適用于設備(bei)單元(yuan)需要頻繁往復移動的場(chang)合，為了防止電(dian)纜(lan)(lan)出現糾(jiu)纏(chan)，磨損(sun)，拉脫，掛和散亂，通常會將電(dian)纜(lan)(lan)放入電(dian)纜(lan)(lan)拖(tuo)鏈中，這(zhe)樣拖(tuo)鏈可對(dui)電(dian)纜(lan)(lan)形成保護使電(dian)纜(lan)(lan)不易磨損(sun)，同時電(dian)纜(lan)(lan)還(huan)能(neng)夠跟隨拖(tuo)鏈實現往復移動，因此拖(tuo)鏈電(dian)纜(lan)(lan)也稱高(gao)柔性電(dian)纜(lan)(lan)。

拖(tuo)鏈(lian)電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)與普(pu)通(tong)電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)相比(bi)，手感上(shang)拖(tuo)鏈(lian)電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)不(bu)比(bi)普(pu)通(tong)電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)軟。拖(tuo)鏈(lian)電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)的導體采用精絞細(xi)銅(tong)絲(si)，而普(pu)通(tong)電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)也采用細(xi)銅(tong)絲(si)，對于相同截面的芯線，拖(tuo)鏈(lian)電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)導體中(zhong)的單絲(si)直徑要(yao)小于普(pu)通(tong)電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)的，為了保(bao)證(zheng)導體的 物理性(xing)(xing)能(neng) 電(dian)(dian)(dian)(dian)性(xing)(xing)能(neng)的穩定，一般用多頭(tou)拉絲(si)4N導體，導體光鮮明亮(liang)，韌性(xing)(xing)好；電(dian)(dian)(dian)(dian)阻率(lv)低，電(dian)(dian)(dian)(dian)線長期(qi)在額(e)定負(fu)載下不(bu)發熱。

拖鏈電纜(lan)(lan)的(de)(de)(de)(de)絕緣要(yao)求很強的(de)(de)(de)(de)耐(nai)機械疲(pi)勞強度，所以是有硬度的(de)(de)(de)(de)；而普通電纜(lan)(lan)的(de)(de)(de)(de)絕緣就是使用不導電的(de)(de)(de)(de)物質(zhi)將帶電體隔離或包(bao)裹起來(lai)。拖鏈電纜(lan)(lan)的(de)(de)(de)(de)護套一般(ban)要(yao)求抗(kang)拉，耐(nai)磨強，韌性(xing)高，而普通電纜(lan)(lan)這方(fang)面的(de)(de)(de)(de)要(yao)求較低。對于大半(ban)徑和低頻率的(de)(de)(de)(de)彎曲移動，普通電纜(lan)(lan)是沒問題的(de)(de)(de)(de)，但機械彎曲壽命與拖鏈電纜(lan)(lan)比(bi)差距(ju)還是很大的(de)(de)(de)(de)。

對于(yu)小(xiao)半(ban)徑的(de)(de)彎(wan)曲移動，或許普通(tong)電纜(lan)根(gen)(gen)本就(jiu)無(wu)法使(shi)(shi)用(yong)，即(ji)使(shi)(shi)是拖(tuo)鏈電纜(lan)也并非可以(yi)無(wu)條件的(de)(de)應用(yong)于(yu)這樣的(de)(de)使(shi)(shi)用(yong)環境，一(yi)(yi)般要(yao)求小(xiao)的(de)(de)彎(wan)曲半(ban)徑為電纜(lan)外徑的(de)(de)7.5倍。如(ru)果彎(wan)曲半(ban)徑小(xiao)于(yu)拖(tuo)鏈電纜(lan)的(de)(de)小(xiao)彎(wan)曲半(ban)徑那么電纜(lan)的(de)(de)機(ji)械彎(wan)曲壽命(ming)也大受影響(xiang)。所以(yi)，對于(yu)小(xiao)彎(wan)曲半(ban)徑的(de)(de)使(shi)(shi)用(yong)環境，選擇拖(tuo)鏈電纜(lan)要(yao)注意電纜(lan)的(de)(de)外徑，若(ruo)一(yi)(yi)根(gen)(gen)多芯電纜(lan)的(de)(de)外徑過大，在(zai)單芯截面不(bu)變的(de)(de)條件下，不(bu)妨可將(jiang)一(yi)(yi)根(gen)(gen)電纜(lan)換成多根(gen)(gen)芯數相對少的(de)(de)電纜(lan)，如(ru)20*0.5可換成2根(gen)(gen)10*0.5的(de)(de)。

隨著社會的(de)(de)(de)不斷發展，對(dui)電(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)纜(lan)(lan)的(de)(de)(de)要(yao)求(qiu)也(ye)日益提高著，電(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)纜(lan)(lan)的(de)(de)(de)分類也(ye)就越加的(de)(de)(de)詳細，比如耐火(huo)、阻燃、無(wu)鹵(lu)電(dian)(dian)(dian)(dian)子(zi)線(xian)(xian)電(dian)(dian)(dian)(dian)纜(lan)(lan)也(ye)就出現在了我們的(de)(de)(de)日常生活(huo)中，那(nei)么對(dui)于這些電(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)纜(lan)(lan)又該(gai)如何的(de)(de)(de)辨別呢？下(xia)面給咱說一下(xia)關于低(di)煙(yan)無(wu)鹵(lu)的(de)(de)(de)電(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)纜(lan)(lan)的(de)(de)(de)識別方(fang)法.

其可以通過以下的幾個方面加以辨別:

1、無(wu)鹵(lu)電(dian)子線的(de)識別(bie)方法之(zhi)表皮(pi)燒(shao)燙法。用電(dian)烙鐵燙一下(xia)絕緣(yuan)層應該會沒(mei)有(you)(you)明(ming)(ming)(ming)顯(xian)凹陷，如果出現有(you)(you)較大凹陷那就說(shuo)明(ming)(ming)(ming)絕緣(yuan)層使用的(de)材料或者工藝存在缺陷。或者可(ke)以(yi)用打火(huo)機燒(shao)烤，正常情況(kuang)下(xia)都是(shi)不易(yi)點燃，長時間燃燒(shao)后電(dian)纜(lan)的(de)絕緣(yuan)層還是(shi)比較完整，沒(mei)有(you)(you)濃(nong)煙與刺激(ji)性氣味，同時直(zhi)徑有(you)(you)所增(zeng)加。如很(hen)容易(yi)點燃，則可(ke)以(yi)確定(ding)電(dian)纜(lan)的(de)絕緣(yuan)層沒(mei)有(you)(you)使用低(di)煙無(wu)鹵(lu)材料(很(hen)可(ke)能是(shi)聚(ju)乙烯(xi)或者交聯(lian)(lian)聚(ju)乙烯(xi)材料)。如果出現比較霧(wu)，則說(shuo)明(ming)(ming)(ming)絕緣(yuan)層使用的(de)是(shi)含鹵(lu)材料。如果長時間燃燒(shao)后，絕緣(yuan)表面脫落嚴重，直(zhi)徑沒(mei)有(you)(you)明(ming)(ming)(ming)顯(xian)的(de)增(zeng)加，則說(shuo)明(ming)(ming)(ming)沒(mei)有(you)(you)進行合適的(de)輻照(zhao)交聯(lian)(lian)工藝處理(li)。

2、無鹵電(dian)子(zi)線的(de)(de)識別方法之(zhi)熱(re)水浸泡(pao)法。把線芯或者電(dian)纜放在(zai)90℃的(de)(de)熱(re)水中(zhong)浸泡(pao)，正常情(qing)況(kuang)下絕緣電(dian)阻不會急(ji)速(su)下降(jiang)并保持(chi)在(zai)0.1MΩ/Km以上。如(ru)絕緣電(dian)阻急(ji)速(su)下降(jiang)甚至(zhi)低于0.009MΩ/Km，則說明沒有(you)經過(guo)合適的(de)(de)輻照交聯工(gong)藝處理。

3、低(di)(di)煙無(wu)鹵(lu)電子(zi)線的識別方(fang)(fang)法之密度(du)對(dui)比法。低(di)(di)煙無(wu)鹵(lu)材料(liao)的密度(du)比水大，可(ke)以剝下少許(xu)絕緣層放入水中，如(ru)果浮(fu)在水面上方(fang)(fang)的，則肯(ken)定(ding)不(bu)是低(di)(di)煙無(wu)鹵(lu)無(wu)鹵(lu)電子(zi)線。
