WDZ電(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)(lan)比WDZN電(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)(lan)價格略(lve)低10~20%。這個看(kan)每家電(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)(lan)廠工(gong)藝和成本價格不一(yi)，電(dian)(dian)(dian)力電(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)(lan)報價，綠寶(bao)電(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)(lan)為您提供，安全(quan)的(de)(de)(de)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)(lan)。中高壓電(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)(lan)一(yi)般采(cai)用(yong)過氧化(hua)(hua)(hua)物(wu)交聯，即用(yong)化(hua)(hua)(hua)學方法將線(xian)性分子通(tong)過化(hua)(hua)(hua)學交聯反應起來，轉化(hua)(hua)(hua)為立體網狀(zhuang)結構。化(hua)(hua)(hua)學交聯一(yi)般還(huan)可分為過氧化(hua)(hua)(hua)物(wu)交聯和接枝交聯兩種。電(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)(lan)就是利用(yong)導體來傳導電(dian)(dian)(dian)流的(de)(de)(de)，因而電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)(lan)的(de)(de)(de)規格都以(yi)導體的(de)(de)(de)截面表示。電(dian)(dian)(dian)力電(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)(lan)的(de)(de)(de)導體，可以(yi)制成整(zheng)根實心的(de)(de)(de)，或是由(you)多根單(dan)線(xian)絞合(he)而成，形(xing)(xing)狀(zhuang)可以(yi)是圓形(xing)(xing)的(de)(de)(de)和扇形(xing)(xing)的(de)(de)(de)結構。

在導(dao)體上、絕(jue)緣層(ceng)上、電(dian)(dian)(dian)纜(lan)(lan)芯上或(huo)(huo)電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜(lan)(lan)外層(ceng)，為了防止外界電(dian)(dian)(dian)磁波(bo)干(gan)擾或(huo)(huo)是(shi)(shi)起均勻電(dian)(dian)(dian)埸作(zuo)用(yong)，還包(bao)有金屬帶、絲或(huo)(huo)半導(dao)電(dian)(dian)(dian)塑料等材料。這些都(dou)稱為屏(ping)蔽層(ceng)。電(dian)(dian)(dian)纜(lan)(lan)就是(shi)(shi)利用(yong)導(dao)體來傳導(dao)電(dian)(dian)(dian)流的(de)，因而電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜(lan)(lan)的(de)規(gui)格都(dou)以(yi)導(dao)體的(de)截(jie)面表示。電(dian)(dian)(dian)力電(dian)(dian)(dian)纜(lan)(lan)的(de)導(dao)體，可以(yi)制成整(zheng)(zheng)根(gen)實心(xin)的(de)，或(huo)(huo)是(shi)(shi)由多根(gen)單線(xian)(xian)絞合而成，形(xing)狀可以(yi)是(shi)(shi)圓形(xing)的(de)和扇形(xing)的(de)結(jie)構。為了檢驗(yan)是(shi)(shi)否(fou)漏(lou)焊，生產廠家(jia)又加了一項中(zhong)間檢驗(yan)裝置(zhi)，將整(zheng)(zheng)盤焊接后的(de)電(dian)(dian)(dian)纜(lan)(lan)進行浸水氣密性試驗(yan)，且進行的(de)檢驗(yan)。

WDZN耐火(huo)電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)的(de)(de)(de)主要(yao)特點是電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)除了能在正常(chang)的(de)(de)(de)工作(zuo)條(tiao)件下傳(chuan)輸(shu)電(dian)(dian)(dian)(dian)(dian)力(li)外(wai)，電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)在著火(huo)燃燒時(shi)仍(reng)能保持(chi)一定時(shi)間的(de)(de)(de)正常(chang)運(yun)行(xing)，適(shi)用(yong)于站(zhan)、地鐵、隧道、高層建筑等與(yu)防(fang)火(huo)安(an)全(quan)和消防(fang)救生有關(guan)的(de)(de)(de)地方。電(dian)(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)主要(yao)有導(dao)體直流電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)、絕緣(yuan)電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)、成品電(dian)(dian)(dian)(dian)(dian)壓試驗(yan)及(ji)(ji)絕緣(yuan)線(xian)芯間電(dian)(dian)(dian)(dian)(dian)壓試驗(yan)，每項都很重要(yao)，導(dao)體電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)直接(jie)反映了電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)傳(chuan)輸(shu)性(xing)能，直接(jie)影響電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)在通電(dian)(dian)(dian)(dian)(dian)運(yun)行(xing)中的(de)(de)(de)溫度、壽命、電(dian)(dian)(dian)(dian)(dian)壓降、以(yi)及(ji)(ji)運(yun)行(xing)安(an)全(quan)。導(dao)體是指能傳(chuan)導(dao)電(dian)(dian)(dian)(dian)(dian)流的(de)(de)(de)物體，又稱為導(dao)電(dian)(dian)(dian)(dian)(dian)線(xian)芯。用(yong)作(zuo)電(dian)(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)導(dao)體的(de)(de)(de)材料，首先要(yao)有良(liang)好的(de)(de)(de)導(dao)電(dian)(dian)(dian)(dian)(dian)性(xing)能，即電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)要(yao)小，以(yi)減少電(dian)(dian)(dian)(dian)(dian)流在線(xian)路上的(de)(de)(de)損耗。損耗與(yu)電(dian)(dian)(dian)(dian)(dian)流大小、電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)大小有直接(jie)關(guan)系(xi)，并(bing)表現(xian)在導(dao)體的(de)(de)(de)發(fa)熱上。
