由于價位問題，不(bu)少人還(huan)將普(pu)(pu)通(tong)電(dian)(dian)(dian)纜(lan)當作(zuo)(zuo)拖(tuo)鏈(lian)電(dian)(dian)(dian)纜(lan)來使(shi)用(yong)，也有人經常將普(pu)(pu)通(tong)電(dian)(dian)(dian)纜(lan)RVV，RVVP，RVVSP稱作(zuo)(zuo)拖(tuo)鏈(lian)電(dian)(dian)(dian)纜(lan)。普(pu)(pu)通(tong)電(dian)(dian)(dian)纜(lan)是否可(ke)用(yong)做拖(tuo)鏈(lian)電(dian)(dian)(dian)纜(lan)呢？

普(pu)通電(dian)纜與高柔性電(dian)纜的區別(bie)：導體的結構(gou)不(bu)同(tong)，絕緣材料不(bu)同(tong)，成纜方式不(bu)同(tong)，分(fen)別(bie)采用(yong)擠管式和擠壓式護套(tao)。

在柔性電(dian)纜中，電(dian)纜頻(pin)繁彎曲受(shou)(shou)(shou)(shou)力(li)(li)移動。普通電(dian)纜在這樣的環境(jing)下運行，因彎曲受(shou)(shou)(shou)(shou)力(li)(li)，纜芯(xin)受(shou)(shou)(shou)(shou)壓而(er)(er)整體承(cheng)受(shou)(shou)(shou)(shou)拉力(li)(li)。開始由于材料的彈性，電(dian)纜尚能(neng)正(zheng)常工作，但運行一(yi)段時(shi)間(jian)后，材料會(hui)(hui)因過度(du)受(shou)(shou)(shou)(shou)力(li)(li)而(er)(er)導致變形。經過這種特殊的擠壓過程(cheng)，纜芯(xin)形成不同的受(shou)(shou)(shou)(shou)壓和拉伸(shen)區域，易產生起旋現象，電(dian)纜隨時(shi)可(ke)能(neng)會(hui)(hui)斷芯(xin)。

高柔性電纜也稱為特種電纜，“特種”就是使用在特殊環境中的電纜，正是如此高柔性電纜通常會有耐油性、耐磨性、抗扭轉、耐彎曲等特性。這是普通電纜無法與其相比的，這也是普通電纜無法代替高柔性電纜的重要原因。
