環市珠江電線電纜是(shi)(shi)用于檢驗電(dian)(dian)(dian)(dian)（磁）能、信息(xi)傳輸和(he)電(dian)(dian)(dian)(dian)磁能變化的電(dian)(dian)(dian)(dian)線產品。廣義(yi)的電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)也叫電(dian)(dian)(dian)(dian)纜(lan)，狹義(yi)的電(dian)(dian)(dian)(dian)纜(lan)是(shi)(shi)指絕(jue)緣電(dian)(dian)(dian)(dian)纜(lan)，可以(yi)(yi)定(ding)義(yi)為：由以(yi)(yi)下幾部(bu)分(fen)組成的集合(he)體；一個或多個絕(jue)緣覆蓋層(ceng)，以(yi)(yi)及它們相應的潛在(zai)(zai)覆蓋層(ceng)、總保護(hu)層(ceng)和(he)外(wai)(wai)護(hu)套，也可以(yi)(yi)在(zai)(zai)電(dian)(dian)(dian)(dian)纜(lan)中包含(han)額外(wai)(wai)的絕(jue)緣導體。

大(da)多(duo)數電(dian)線(xian)電(dian)纜產(chan)品(pin)(pin)具有(you)相同的(de)橫截面(mian)形狀（忽略制造誤差）和長帶，因為(wei)它們在系統或設備中用(yong)作線(xian)或線(xian)圈。因此(ci)，要(yao)*分析電(dian)纜產(chan)品(pin)(pin)的(de)結(jie)構結(jie)構，只(zhi)需要(yao)對其橫截面(mian)進行觀察分析即可。電(dian)線(xian)電(dian)纜產(chan)品(pin)(pin)的(de)結(jie)構元件(jian)一般可分為(wei)四種主(zhu)要(yao)結(jie)構元件(jian)：導體(ti)、絕緣層、屏(ping)蔽和護套，以及填充元件(jian)和抗拉元件(jian)。根(gen)據產(chan)品(pin)(pin)的(de)使用(yong)要(yao)求和應(ying)用(yong)，有(you)些產(chan)品(pin)(pin)的(de)結(jie)構很簡(jian)單。環市珠江電(dian)纜

電纜編織層的作用：

1、金(jin)屬材(cai)料編織(zhi)層(ceng)(ceng)的(de)作用：金(jin)屬材(cai)料編織(zhi)層(ceng)(ceng)有鋁鎂絲編織(zhi)層(ceng)(ceng)和銅編織(zhi)層(ceng)(ceng)兩(liang)種。

2、鋁鎂絲編織的(de)作(zuo)用：維(wei)修機械(xie)設(she)備。例如(ru)船用電(dian)線電(dian)纜cf31。同時還可以起到電(dian)磁場屏蔽作(zuo)用。可承(cheng)受垂直(zhi)斷裂力，例如(ru)用于深海地質勘探的(de)WC-GC和WCT型磁纜。

3、銅(tong)(tong)編織(zhi)的(de)(de)(de)主要作(zuo)用(yong)：鐵(tie)芯(xin)絕(jue)緣層(ceng)外側(ce)的(de)(de)(de)銅(tong)(tong)編織(zhi)層(ceng)，與(yu)接(jie)地的(de)(de)(de)鐵(tie)芯(xin)接(jie)觸良(liang)好或(huo)用(yong)作(zuo)接(jie)地線(xian)，可即時顯示漏電(dian)(dian)(dian)情況。還(huan)可處理(li)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)(lan)表面電(dian)(dian)(dian)位差的(de)(de)(de)截留作(zuo)用(yong)，粘合傳輸線(xian)，處理(li)感應電(dian)(dian)(dian)流，如高壓電(dian)(dian)(dian)纜(lan)(lan)的(de)(de)(de)一般屏(ping)蔽。截取深(shen)藍色電(dian)(dian)(dian)鍍銅(tong)(tong)編織(zhi)電(dian)(dian)(dian)纜(lan)(lan)、變頻銅(tong)(tong)編織(zhi)電(dian)(dian)(dian)纜(lan)(lan)等干擾信(xin)號的(de)(de)(de)作(zuo)用(yong)。

4、化(hua)纖(xian)(xian)編(bian)織(zhi)層(ceng)的作用(yong)：對于(yu)電(dian)纜(lan)來說，化(hua)纖(xian)(xian)編(bian)織(zhi)層(ceng)是(shi)其光保(bao)(bao)護(hu)層(ceng)的一(yi)種方式。其作用(yong)是(shi)保(bao)(bao)護(hu)絕(jue)緣(yuan)層(ceng)不因各種光、熱、超低溫、強(qiang)酸強(qiang)堿及(ji)外部機械設備(bei)的腐(fu)蝕而損(sun)壞或少(shao)損(sun)壞，保(bao)(bao)證電(dian)纜(lan)的可(ke)靠運行。對于(yu)化(hua)纖(xian)(xian)制成的電(dian)纜(lan)和編(bian)織(zhi)物，通(tong)常位于(yu)保(bao)(bao)護(hu)層(ceng)的中間，從而提高保(bao)(bao)護(hu)層(ceng)的耐磨(mo)性和抗壓(ya)強(qiang)度。棉紗、亞麻等化(hua)學纖(xian)(xian)維(wei)交織(zhi)在一(yi)起，增(zeng)加了外殼(ke)的抗壓(ya)強(qiang)度。
