電線電纜編織的作用

電線(xian)電纜主(zhu)要由導電線(xian)芯(xin)，絕緣(yuan)層、護套層三個(ge)基(ji)本的(de)(de)結(jie)構元件(jian)組成．電線(xian)電纜主(zhu)要由導電線(xian)芯(xin)，絕緣(yuan)層、護套層三個(ge)基(ji)本的(de)(de)結(jie)構元件(jian)組成．

電(dian)(dian)(dian)線與電(dian)(dian)(dian)纜的(de)(de)(de)(de)區別(bie)沒有(you)嚴格的(de)(de)(de)(de)界限(xian)，但(dan)從廣(guang)意上(shang)講，電(dian)(dian)(dian)纜結構較復雜，它有(you)復雜的(de)(de)(de)(de)護套層(ceng)(ceng)，而電(dian)(dian)(dian)線結構比較簡(jian)單有(you)的(de)(de)(de)(de)僅有(you)導體(ti)和(he)(he)絕緣層(ceng)(ceng)，有(you)的(de)(de)(de)(de)只有(you)編織涂臘輕(qing)便護層(ceng)(ceng)或包(bao)覆一(yi)層(ceng)(ceng)輕(qing)型(xing)的(de)(de)(de)(de)軟護層(ceng)(ceng)．電(dian)(dian)(dian)線電(dian)(dian)(dian)纜的(de)(de)(de)(de)導電(dian)(dian)(dian)線芯是(shi)用于傳輸電(dian)(dian)(dian)流的(de)(de)(de)(de)．為(wei)減小電(dian)(dian)(dian)能(neng)損耗及(ji)電(dian)(dian)(dian)壓降，導電(dian)(dian)(dian)線芯一(yi)般(ban)選(xuan)用導電(dian)(dian)(dian)率高的(de)(de)(de)(de)銅和(he)(he)鋁制(zhi)成．絕緣層(ceng)(ceng)的(de)(de)(de)(de)作用是(shi)防止電(dian)(dian)(dian)流沿徑向泄漏，保證(zheng)使用安全．因此要(yao)求絕緣層(ceng)(ceng)要(yao)具有(you)良(liang)好的(de)(de)(de)(de)電(dian)(dian)(dian)絕緣性(xing)能(neng)．耐(nai)熱性(xing)能(neng)和(he)(he)一(yi)定的(de)(de)(de)(de)機械強(qiang)度．

在絕緣(yuan)線芯或成纜(lan)(lan)線芯外(wai)(wai)面的(de)保(bao)護(hu)覆蓋層(ceng)(ceng)稱(cheng)為(wei)電纜(lan)(lan)的(de)護(hu)層(ceng)(ceng)（在護(hu)層(ceng)(ceng)外(wai)(wai)面的(de)保(bao)護(hu)覆蓋層(ceng)(ceng)則稱(cheng)為(wei)外(wai)(wai)護(hu)層(ceng)(ceng)）．護(hu)層(ceng)(ceng)的(de)主(zhu)要(yao)作用是(shi)保(bao)護(hu)絕緣(yuan)層(ceng)(ceng)．它的(de)主(zhu)要(yao)性能(neng)是(shi)防(fang)(fang)(fang)潮、防(fang)(fang)(fang)油(you)、防(fang)(fang)(fang)腐．防(fang)(fang)(fang)日光老(lao)化、耐燃，以及機械保(bao)護(hu)(外(wai)(wai)護(hu)層(ceng)(ceng)的(de)作用主(zhu)要(yao)是(shi)加強對電纜(lan)(lan)的(de)機械保(bao)護(hu)．它承(cheng)受(shou)拉力、磕碰)，還(huan)具有(you)防(fang)(fang)(fang)電、防(fang)(fang)(fang)磁干抗(kang)等作用

從電(dian)(dian)線電(dian)(dian)纜(lan)護層(ceng)(ceng)的角(jiao)度講，編(bian)織(zhi)(zhi)(zhi)是(shi)電(dian)(dian)線電(dian)(dian)纜(lan)許(xu)多(duo)種(zhong)護層(ceng)(ceng)或外護層(ceng)(ceng)之(zhi)一．但是(shi)，根據電(dian)(dian)線電(dian)(dian)纜(lan)編(bian)織(zhi)(zhi)(zhi)層(ceng)(ceng)使用的材(cai)料及編(bian)織(zhi)(zhi)(zhi)層(ceng)(ceng)在電(dian)(dian)線電(dian)(dian)纜(lan)結構(gou)中(zhong)的不(bu)同部位(wei)，編(bian)織(zhi)(zhi)(zhi)層(ceng)(ceng)的作用顯然是(shi)不(bu)同的．

一、纖維(wei)編(bian)織層的(de)作用(yong)

對(dui)于(yu)電(dian)線(xian)，纖維編織層(ceng)(ceng)(ceng)是(shi)其(qi)輕型(xing)保護(hu)層(ceng)(ceng)(ceng)的一(yi)種(zhong)形式(shi)．它 的主要作用(yong)是(shi)保護(hu)絕緣不(bu)受或少(shao)受各種(zhong)光，熱、潮．低溫、 酸堿氣體等的侵蝕和外界機械力的損(sun)傷，確(que)保電(dian)線(xian)的安全運行．而對(dui)于(yu)電(dian)纜(lan)，纖維編織層(ceng)(ceng)(ceng)往往是(shi)在護(hu)層(ceng)(ceng)(ceng)的中間，借(jie)以(yi)增 強護(hu)層(ceng)(ceng)(ceng)的抗撕裂強度，如加強型(xing)護(hu)套就是(shi)在橡皮或塑料護(hu)層(ceng)(ceng)(ceng)的中間加入棉紗，麻等纖維編織層(ceng)(ceng)(ceng)，以(yi)提高護(hu)層(ceng)(ceng)(ceng)強度的．

二、金屬編織層的作(zuo)用(yong)

金屬編(bian)織(zhi)層(ceng)主(zhu)(zhu)要有銅絲編(bian)織(zhi)層(ceng)和鋼(gang)絲（鐵絲）編(bian)織(zhi)層(ceng)兩種(zhong)，銅絲編(bian)織(zhi)的主(zhu)(zhu)要作用是：

1.防電磁(ci)干擾的屏蔽作(zuo)用如鍍錫銅絲編織的藍用電纜、銅絲編織的控制電纜等．

2.消除電(dian)力(li)電(dian)纜(lan)表(biao)面電(dian)位的(de)屏(ping)蔽(bi)作用．它起束縛電(dian)力(li)線和消除感(gan)應電(dian)，如高壓電(dian)纜(lan)的(de)總(zong)屏(ping)蔽(bi)．

3.安全保護(hu)的屏(ping)蔽作用．在主芯絕緣(yuan)外編織銅絲并(bing)與地(di)芯良好的接觸或作地(di)線用，能及時反應漏(lou)電情況，如屏(ping)蔽型礦用電纜。

鋼絲編織的主要作用是：

1、機(ji)械保(bao)護作用(yong)(yong)．如(ru)船用(yong)(yong)電(dian)力電(dian)纜CF31型．

2、承(cheng)受縱向拉斷力(li)，如(ru)海洋地(di)質勘探用測(ce)磁電(dian)纜WC-GC、WCT型．

3、磁場屏蔽.
