產品詳情

電(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)纜（power cable），用(yong)于(yu)(yu)(yu)傳輸和分配(pei)電(dian)(dian)(dian)(dian)能的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)纜。常用(yong)于(yu)(yu)(yu)城(cheng)市(shi)地下電(dian)(dian)(dian)(dian)網、發電(dian)(dian)(dian)(dian)站的(de)(de)(de)(de)引(yin)出線(xian)(xian)路、工礦企業的(de)(de)(de)(de)內部供電(dian)(dian)(dian)(dian)及(ji)過江、過海(hai)的(de)(de)(de)(de)水(shui)下輸電(dian)(dian)(dian)(dian)線(xian)(xian)。在電(dian)(dian)(dian)(dian)力線(xian)(xian)路中，電(dian)(dian)(dian)(dian)纜所占的(de)(de)(de)(de)比(bi)重正(zheng)逐漸增加(jia)。電(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)纜是在電(dian)(dian)(dian)(dian)力系統的(de)(de)(de)(de)主于(yu)(yu)(yu)線(xian)(xian)路中用(yong)以傳輸和分配(pei)大(da)功(gong)率電(dian)(dian)(dian)(dian)能的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)纜產品，其(qi)中包括1-500KV以及(ji)以上各種電(dian)(dian)(dian)(dian)壓(ya)等級，各種絕緣的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)纜。

基本結構

電力電纜的基本結(jie)構由線芯（導體(ti)）、絕(jue)緣層、屏(ping)蔽層和保護層四部分組成(cheng)。

（1）線芯

線(xian)芯是(shi)(shi)電力(li)電纜(lan)的導電部(bu)分(fen)，用來輸送電能，是(shi)(shi)電力(li)電纜(lan)的主要部(bu)分(fen)。

（2）絕緣層

絕緣層是將(jiang)線(xian)芯與大地以及不同相的(de)線(xian)芯間在電(dian)(dian)氣上(shang)彼(bi)此隔離，保證電(dian)(dian)能輸送，是電(dian)(dian)力電(dian)(dian)纜(lan)結構(gou)中(zhong)不可缺少的(de)組成部(bu)分。

（3）屏蔽層

15KV及以上的(de)電力電纜(lan)一般都(dou)有導體(ti)屏(ping)蔽(bi)層(ceng)和絕緣屏(ping)蔽(bi)層(ceng)。

（4）保護層

保(bao)護層(ceng)的(de)作(zuo)用是(shi)保(bao)護電力(li)電纜免受(shou)外界雜(za)質和水(shui)分的(de)侵(qin)入，以及防(fang)止外力(li)直接損壞電力(li)電纜。

優點

1占地(di)(di)(di)少.一般埋設(she)于土壤中(zhong)或敷設(she)于室內，溝道，隧道中(zhong)，線間絕緣(yuan)距離小(xiao)，不用桿塔，占地(di)(di)(di)少，基(ji)本不占地(di)(di)(di)面(mian)上空間．

2可(ke)靠(kao)(kao)性(xing)高．受氣候(hou)條件(jian)和周圍環境影響小(xiao)，傳輸性(xing)能穩(wen)定(ding)，可(ke)靠(kao)(kao)性(xing)高．

3具有向超(chao)(chao)高(gao)壓，大(da)容量發展的更為有利的條件，如低(di)溫，超(chao)(chao)導(dao)電力電纜等．

4分(fen)布(bu)電容(rong)較大．

5維(wei)護工作量少.

6電(dian)擊可能性小．
