 YJV電(dian)纜的結構

　　YJV電纜(lan)由內而外分類為(wei)線(xian)芯(xin)(xin)、導體絕(jue)(jue)緣(yuan)層(ceng)(ceng)、填充(chong)層(ceng)(ceng)、屏(ping)蔽層(ceng)(ceng)、鋼(gang)帶鎧(kai)裝(zhuang)、護(hu)(hu)(hu)套(tao)層(ceng)(ceng)。其中，YJV的(de)(de)線(xian)芯(xin)(xin)主要(yao)以(yi)銅芯(xin)(xin)為(wei)主，鋁芯(xin)(xin)的(de)(de)應用(yong)(yong)較少；導體絕(jue)(jue)緣(yuan)層(ceng)(ceng)為(wei)聚氯(lv)乙烯絕(jue)(jue)緣(yuan)；填充(chong)層(ceng)(ceng)為(wei)了充(chong)實線(xian)芯(xin)(xin)之(zhi)間(jian)的(de)(de)縫(feng)隙，同時起(qi)到保護(hu)(hu)(hu)線(xian)芯(xin)(xin)的(de)(de)作用(yong)(yong)，其材質多為(wei)較軟(ruan)的(de)(de)尼龍類材料；一般在15KV及以(yi)上的(de)(de)電力電纜(lan)一般都有導體屏(ping)蔽層(ceng)(ceng)和絕(jue)(jue)緣(yuan)屏(ping)蔽層(ceng)(ceng)；鋼(gang)帶鎧(kai)裝(zhuang)是包在線(xian)芯(xin)(xin)外圍的(de)(de)一層(ceng)(ceng)鋼(gang)制保護(hu)(hu)(hu)層(ceng)(ceng)，起(qi)到防止電纜(lan)被(bei)擠(ji)壓(ya)變形的(de)(de)作用(yong)(yong)，鎧(kai)裝(zhuang)YJV電纜(lan)多用(yong)(yong)于(yu)地埋；護(hu)(hu)(hu)套(tao)層(ceng)(ceng)是YJV電纜(lan)最外面(mian)的(de)(de)一層(ceng)(ceng)，材質為(wei)聚乙烯，起(qi)到絕(jue)(jue)緣(yuan)、保護(hu)(hu)(hu)的(de)(de)作用(yong)(yong)。

YJV電纜的分類

　　根據電(dian)(dian)壓(ya)進行分類并沒有(you)嚴格的劃(hua)分，只是根據業(ye)內普遍認(ren)同的說法(fa)進行劃(hua)分。根據使用電(dian)(dian)壓(ya)，YJV電(dian)(dian)纜可分為(wei)

　　1KV及以下為低壓電纜；

　　1KV~10KV為中壓電纜；

　　10KV~35KV為高壓電(dian)纜；

　　35~220KV為特高(gao)壓電纜。
