YJV電力電纜

電力電纜是用于傳輸和分配電能的電纜,電力電纜常用于城市地下電網、發電站引出線路、工礦企業內部供電及過江海水下輸電線。
在電力線路中,電纜所占比重正逐漸添加。電力電纜是在電力系統的骨干線路中用以傳輸和分配大功率電能的電纜產品,包含1-500KV以及以上各種電壓等級,各種絕緣的電力電纜。

電(dian)(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)的(de)運用(yong)(yong)至今已有百余年(nian)(nian)(nian)(nian)前史。1879年(nian)(nian)(nian)(nian),美國(guo)創(chuang)造家T.A.愛(ai)迪生在(zai)(zai)銅棒上(shang)包繞黃麻(ma)并將其穿入鐵(tie)管(guan)內(nei),然后填(tian)充瀝(li)青(qing)混合物制成(cheng)(cheng)電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)。他將此電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)敷設(she)于紐(niu)約,創(chuang)始了(le)地下輸(shu)電(dian)(dian)(dian)(dian)(dian)。次年(nian)(nian)(nian)(nian),英國(guo)人卡倫德創(chuang)造瀝(li)青(qing)浸漬紙絕(jue)緣電(dian)(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)。1889年(nian)(nian)(nian)(nian),英國(guo)人S.Z.費蘭梯在(zai)(zai)倫敦與德特福德之間敷設(she)了(le)10千伏(fu)油浸紙絕(jue)緣電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)。1908年(nian)(nian)(nian)(nian),英國(guo)建成(cheng)(cheng)20千伏(fu)電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)網。電(dian)(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)得到(dao)越來越廣的(de)使用(yong)(yong)。1911年(nian)(nian)(nian)(nian),德國(guo)敷設(she)成(cheng)(cheng)60千伏(fu)高(gao)(gao)(gao)壓(ya)(ya)電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan),開端了(le)高(gao)(gao)(gao)壓(ya)(ya)電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)的(de)開展(zhan)。1913年(nian)(nian)(nian)(nian),德國(guo)人M.霍希施(shi)泰特研制成(cheng)(cheng)分相屏(ping)蔽電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan),改進了(le)電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)內(nei)部電(dian)(dian)(dian)(dian)(dian)場散布,消除了(le)絕(jue)緣外(wai)表(biao)的(de)正切應力,成(cheng)(cheng)為電(dian)(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)開展(zhan)中(zhong)的(de)里程碑(bei)。1952年(nian)(nian)(nian)(nian),瑞典在(zai)(zai)北(bei)部發(fa)電(dian)(dian)(dian)(dian)(dian)廠(chang)敷設(she)了(le)380千伏(fu)超(chao)(chao)高(gao)(gao)(gao)壓(ya)(ya)電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan),完成(cheng)(cheng)了(le)超(chao)(chao)高(gao)(gao)(gao)壓(ya)(ya)電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)的(de)使用(yong)(yong)。到(dao)80年(nian)(nian)(nian)(nian)代(dai)已制成(cheng)(cheng)1100千伏(fu)、1200千伏(fu)的(de)特高(gao)(gao)(gao)壓(ya)(ya)電(dian)(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)。
