性能區別

控制電纜具有防潮、防腐和防損傷等特點,可以敷設在隧道或電纜溝內。 [1]  電力電纜在電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力系(xi)統主干線中用以傳輸和(he)(he)分配大功率電(dian)(dian)(dian)(dian)(dian)(dian)(dian)能，控(kong)制(zhi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)從電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力系(xi)統的(de)(de)配電(dian)(dian)(dian)(dian)(dian)(dian)(dian)點把(ba)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)能直接(jie)傳輸到各種(zhong)用電(dian)(dian)(dian)(dian)(dian)(dian)(dian)設(she)備器具的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源連接(jie)線路。電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)的(de)(de)額(e)定電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓一般為0.6/1kV及以上，控(kong)制(zhi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)主要為450/750V。同樣規格(ge)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)和(he)(he)控(kong)制(zhi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)在生產時，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)的(de)(de)絕緣和(he)(he)護套厚度比(bi)控(kong)制(zhi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)厚。

(一)控制(zhi)電(dian)纜屬于電(dian)器裝(zhuang)備(bei)用電(dian)纜，和電(dian)力(li)電(dian)纜是電(dian)纜五大類中的2個(ge)。

(二)控制電(dian)纜的(de)(de)標(biao)準是9330，電(dian)力電(dian)纜的(de)(de)標(biao)準是GB12706。

(三)控制電纜的(de)絕緣(yuan)線芯(xin)的(de)顏色(se)一般都(dou)是(shi)黑色(se)印白(bai)字、還有(you)電力電纜低壓一般都(dou)是(shi)分色(se)的(de)。

(四)控制電(dian)(dian)纜的(de)截(jie)面(mian)一般(ban)都(dou)不會超過10平方，電(dian)(dian)力電(dian)(dian)纜主要(yao)是輸送電(dian)(dian)力的(de)，一般(ban)都(dou)是大截(jie)面(mian)。

由于以上大家(jia)講到的(de)(de)原因(yin),電(dian)力電(dian)纜的(de)(de)規格一(yi)般可(ke)以較大，大到500平方(fang)(fang)(常規廠(chang)家(jia)能生產(chan)的(de)(de)范圍)，再大的(de)(de)截(jie)面(mian)一(yi)般能做的(de)(de)廠(chang)家(jia)就相對少了(le)，而控制電(dian)纜的(de)(de)截(jie)面(mian)一(yi)般較小，大的(de)(de)一(yi)般不超過(guo)10平方(fang)(fang)。

從電(dian)(dian)纜(lan)芯(xin)數上講,電(dian)(dian)力電(dian)(dian)纜(lan)根(gen)據電(dian)(dian)網要(yao)求(qiu),多(duo)一(yi)般為5芯(xin),而(er)控制電(dian)(dian)纜(lan)傳輸控制信號(hao)用，芯(xin)數較(jiao)多(duo)，根(gen)據標準(zhun)來講多(duo)的有(you)61芯(xin)，但也可以根(gen)據用戶要(yao)求(qiu)生產了(le)。

控制電纜發展前景：電線電纜行業是中國僅次于汽車行業的二大行業，產品品種滿足率和國內市場占有率均超過90%。在世界范圍內，中國電線電纜總產值已超過美國，成為一大電線電纜生產國。伴隨著中國電線電纜行業高速發展，新增企業數量不斷上升，行業整體技術水平得到大幅提高。

中(zhong)(zhong)國經濟持續快速的(de)增(zeng)長，為線(xian)纜(lan)(lan)產品提供了巨(ju)大(da)(da)的(de)市(shi)(shi)場(chang)空間，中(zhong)(zhong)國市(shi)(shi)場(chang)強烈的(de)誘惑力(li)，使(shi)得世界都把目(mu)(mu)光聚(ju)焦于中(zhong)(zhong)國市(shi)(shi)場(chang)，在改革(ge)開放短(duan)短(duan)的(de)幾十年，中(zhong)(zhong)國線(xian)纜(lan)(lan)制造(zao)業(ye)所形成的(de)龐大(da)(da)生產能(neng)力(li)讓(rang)世界刮(gua)目(mu)(mu)相看。隨著中(zhong)(zhong)國電(dian)力(li)工業(ye)、數據通(tong)信(xin)業(ye)、城市(shi)(shi)軌道交通(tong)業(ye)、汽車業(ye)以及造(zao)船等行業(ye)規模(mo)的(de)不斷(duan)擴大(da)(da)，對電(dian)線(xian)電(dian)纜(lan)(lan)的(de)需求(qiu)也將(jiang)迅速增(zeng)長，未來電(dian)線(xian)電(dian)纜(lan)(lan)業(ye)還有巨(ju)大(da)(da)的(de)發展潛力(li)。

2008年11月，我國為應對世界金融危機(ji)(ji)，政府(fu)決定投入4萬億元拉動內需，其中有(you)大約40%以上用于城(cheng)鄉(xiang)電(dian)網建(jian)設與改(gai)(gai)造(zao)。全國電(dian)線電(dian)纜(lan)行業又有(you)了良(liang)好(hao)的市(shi)場機(ji)(ji)遇，各地電(dian)線電(dian)纜(lan)企業抓住機(ji)(ji)遇，迎接新一輪(lun)城(cheng)鄉(xiang)電(dian)網建(jian)設與改(gai)(gai)造(zao)。
