生活中電(dian)(dian)(dian)纜(lan)(lan)(lan)型(xing)號種類很多(duo)，按GB/T2900.10-1984，電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)(lan)(lan)定義為(wei)：用以傳輸電(dian)(dian)(dian)能(neng)、信(xin)息和實現電(dian)(dian)(dian)磁能(neng)轉換的(de)(de)(de)線(xian)材產品。為(wei)便于選(xuan)用及(ji)提高產品的(de)(de)(de)適用性，我國(guo)的(de)(de)(de)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)(lan)(lan)產品按其用途可分為(wei)下(xia)(xia)列五大類。類別(bie)里有裸電(dian)(dian)(dian)線(xian)、繞組線(xian)、電(dian)(dian)(dian)力電(dian)(dian)(dian)纜(lan)(lan)(lan)、通信(xin)電(dian)(dian)(dian)纜(lan)(lan)(lan)、電(dian)(dian)(dian)氣裝(zhuang)備用電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)(lan)(lan)。今(jin)天主(zhu)要講(jiang)一下(xia)(xia)細分類里中壓(ya)和高壓(ya)電(dian)(dian)(dian)纜(lan)(lan)(lan)，那么中壓(ya)和高壓(ya)電(dian)(dian)(dian)纜(lan)(lan)(lan)有哪些型(xing)號中壓(ya)電(dian)(dian)(dian)纜(lan)(lan)(lan)和高壓(ya)電(dian)(dian)(dian)纜(lan)(lan)(lan)的(de)(de)(de)執(zhi)行標準又是什么呢？

01.中壓(ya)電纜和高(gao)壓(ya)電纜的執行(xing)標(biao)準

中壓(ya)交聯聚乙(yi)烯絕緣電(dian)(dian)力(li)電(dian)(dian)纜(電(dian)(dian)壓(ya)等級：6/6KV-26/35KV;執(zhi)行標準：GB/T12706.2-2008)中壓(ya)交聯聚乙(yi)電(dian)(dian)纜采(cai)用(yong)了全干式化學交聯方法使(shi)(shi)用(yong)聚乙(yi)烯分子由線(xian)型分子結(jie)構(gou)(gou)變為空(kong)間網狀結(jie)構(gou)(gou)，使(shi)(shi)熱(re)塑性(xing)(xing)的(de)聚乙(yi)烯轉變為熱(re)固(gu)性(xing)(xing)的(de)交聯聚乙(yi)烯，使(shi)(shi)其機械性(xing)(xing)能(neng)、熱(re)老化性(xing)(xing)能(neng)及環境(jing)應力(li)能(neng)力(li)在很大的(de)程度(du)上(shang)得到提高，并具有優良的(de)電(dian)(dian)氣性(xing)(xing)能(neng)。具有異體正常(chang)運行溫度(du)高、結(jie)構(gou)(gou)簡單、外徑小、重量輕、使(shi)(shi)用(yong)方便(bian)、不(bu)受敷設落差限(xian)制等特性(xing)(xing)。適用(yong)于工頻額定電(dian)(dian)壓(ya)1-35KV配電(dian)(dian)系統(tong)。

高壓交聯聚乙烯絕緣電力(li)電纜(電壓等級(ji)：64/110KV，執行標準：GB/T 11017-2014;127/220KV、290/500KV)。

高壓電纜從內到外的組成部分包括:導體、絕緣、內護層、填充料(鎧裝)、外絕緣。當然，鎧裝高壓電纜主要用于地埋，可以抵抗地面上高強度的壓迫，同時可防止其他外力損壞。

02.中壓和高壓電纜型號中壓電纜主要種類有YJV電纜、VV電纜、YJLV電纜、VLV電纜。

YJV電纜全(quan)稱交聯(lian)聚(ju)乙(yi)烯(xi)絕緣聚(ju)氯乙(yi)烯(xi)護套(tao)電力電纜(銅芯)

VV電(dian)纜全稱聚(ju)氯乙烯絕(jue)緣聚(ju)氯乙烯護(hu)套(tao)電(dian)力電(dian)纜(銅芯)

YJLV電纜全稱交聯聚(ju)(ju)乙(yi)烯絕緣聚(ju)(ju)氯乙(yi)烯護套鋁芯電力電纜

VLV電(dian)(dian)纜(lan)全稱聚氯乙烯(xi)絕緣聚氯乙烯(xi)護套鋁芯(xin)電(dian)(dian)力(li)電(dian)(dian)纜(lan)
