高壓電纜|什么是高壓電纜

高壓電纜

高壓電纜是(shi)電力(li)(li)電纜的一種，是(shi)指用(yong)于(yu)傳輸(shu)1kv-1000kv之(zhi)間的電力(li)(li)電纜，多應用(yong)于(yu)電力(li)(li)傳輸(shu)和分(fen)配。

高壓電纜結構

高壓電纜從內到外(wai)的組成部分包括：導體、絕(jue)緣、內護層、填充料（鎧(kai)裝）、外(wai)絕(jue)緣。當然(ran)，鎧(kai)裝高壓電纜主要用于地埋，可以抵抗(kang)地面上高強度的壓迫，同時可防止其(qi)他(ta)外(wai)力損壞。

高壓電纜使用特性

該產品適用于交流額定(ding)(ding)電(dian)(dian)壓35KV及以下供(gong)輸配電(dian)(dian)能固定(ding)(ding)廒設線路用，電(dian)(dian)纜(lan)導體的最(zui)高(gao)長(chang)期工(gong)作(zuo)溫度90度，短(duan)路時（最(zui)長(chang)時間不超過(guo)5S），電(dian)(dian)纜(lan)導體最(zui)高(gao)溫度不超過(guo)250度。

高壓電纜種類

中(zhong)壓電(dian)(dian)(dian)(dian)纜主要種類有YJV電(dian)(dian)(dian)(dian)纜、VV電(dian)(dian)(dian)(dian)纜、YJLV電(dian)(dian)(dian)(dian)纜、VLV電(dian)(dian)(dian)(dian)纜。YJV電(dian)(dian)(dian)(dian)纜全(quan)(quan)稱(cheng)交(jiao)聯(lian)聚(ju)(ju)乙(yi)烯(xi)絕緣(yuan)聚(ju)(ju)氯乙(yi)烯(xi)護(hu)套電(dian)(dian)(dian)(dian)力(li)(li)(li)電(dian)(dian)(dian)(dian)纜（銅(tong)芯(xin)）。VV電(dian)(dian)(dian)(dian)纜全(quan)(quan)稱(cheng)聚(ju)(ju)氯乙(yi)烯(xi)絕緣(yuan)聚(ju)(ju)氯乙(yi)烯(xi)護(hu)套電(dian)(dian)(dian)(dian)力(li)(li)(li)電(dian)(dian)(dian)(dian)纜（銅(tong)芯(xin)）。YJLV電(dian)(dian)(dian)(dian)纜全(quan)(quan)稱(cheng)交(jiao)聯(lian)聚(ju)(ju)乙(yi)烯(xi)絕緣(yuan)聚(ju)(ju)氯乙(yi)烯(xi)護(hu)套鋁芯(xin)電(dian)(dian)(dian)(dian)力(li)(li)(li)電(dian)(dian)(dian)(dian)纜。VLV電(dian)(dian)(dian)(dian)纜全(quan)(quan)稱(cheng)聚(ju)(ju)氯乙(yi)烯(xi)絕緣(yuan)聚(ju)(ju)氯乙(yi)烯(xi)護(hu)套鋁芯(xin)電(dian)(dian)(dian)(dian)力(li)(li)(li)電(dian)(dian)(dian)(dian)纜，由于銅(tong)導(dao)體的(de)出色導(dao)電(dian)(dian)(dian)(dian)性(xing)能，越(yue)(yue)來越(yue)(yue)多(duo)的(de)工程(cheng)采(cai)用(yong)銅(tong)芯(xin)電(dian)(dian)(dian)(dian)力(li)(li)(li)電(dian)(dian)(dian)(dian)纜作為供(gong)電(dian)(dian)(dian)(dian)系統的(de)主干道，而鋁芯(xin)電(dian)(dian)(dian)(dian)力(li)(li)(li)電(dian)(dian)(dian)(dian)纜的(de)應用(yong)則(ze)較少，尤其是在越(yue)(yue)高壓的(de)電(dian)(dian)(dian)(dian)力(li)(li)(li)系統中(zhong)，選擇銅(tong)芯(xin)電(dian)(dian)(dian)(dian)纜的(de)就(jiu)越(yue)(yue)多(duo)。
