珠江高壓(ya)電纜YJV22
珠江電纜中高壓電纜
怎么差異高壓電纜和低壓電纜
首要(yao)能夠看結構。高壓電纜層數多，剝開最(zui)外層里邊(bian)還(huan)有(you)鎧(kai)裝、屏蔽層、絕緣(yuan)層、導體等(deng)。低壓電纜一(yi)般撥開最(zui)外層，里邊(bian)便(bian)是絕緣(yuan)層或許(xu)導線。
其次(ci)，高壓(ya)電纜絕緣層(ceng)比較厚，低(di)壓(ya)電纜絕緣層(ceng)比較薄(bo)。低(di)壓(ya)電纜絕緣層(ceng)一般在(zai)3毫米(mi)(mi)以(yi)內，高壓(ya)電纜絕緣層(ceng)一般在(zai)5毫米(mi)(mi)以(yi)上(shang)。
再次，能夠看電(dian)(dian)纜(lan)(lan)最外(wai)層(ceng)的銘牌。在電(dian)(dian)纜(lan)(lan)的最外(wai)層(ceng)上一般都印刷了電(dian)(dian)纜(lan)(lan)的相關參數(shu)，其中就包含電(dian)(dian)纜(lan)(lan)類型、截面(mian)積、額外(wai)電(dian)(dian)壓、長度等(deng)參數(shu)
高(gao)(gao)壓電(dian)(dian)纜是(shi)電(dian)(dian)壓等級(ji)在1kV伏以上至750KV總稱高(gao)(gao)壓電(dian)(dian)纜。首要用處是(shi)電(dian)(dian)力(li)部門用于運(yun)送(song)電(dian)(dian)力(li)，電(dian)(dian)壓改換之用。一(yi)般常用于遠(yuan)距(ju)離運(yun)送(song)電(dian)(dian)力(li)，變電(dian)(dian)站電(dian)(dian)壓等級(ji)改換。咱們常見常用的電(dian)(dian)壓等級(ji)都(dou)(dou)在220KV以下。遠(yuan)距(ju)離運(yun)送(song)電(dian)(dian)力(li)電(dian)(dian)壓等級(ji)都(dou)(dou)是(shi)超高(gao)(gao)壓。都(dou)(dou)是(shi)電(dian)(dian)力(li)部門指定專門電(dian)(dian)力(li)工人施工、專門保護(hu)。對這方面(mian)的高(gao)(gao)壓電(dian)(dian)纜許多人都(dou)(dou)不(bu)太(tai)清楚的。
高(gao)壓(ya)(ya)(ya)電(dian)(dian)纜(lan)依據耐壓(ya)(ya)(ya)等(deng)(deng)級有(you)多種(zhong)類型(xing)分為：1。油浸紙絕緣(yuan)電(dian)(dian)纜(lan)。耐壓(ya)(ya)(ya)等(deng)(deng)級有(you)1KV～750KV。2。塑料絕緣(yuan)電(dian)(dian)纜(lan)。耐壓(ya)(ya)(ya)等(deng)(deng)級1KV～220KV。3。橡皮絕緣(yuan)電(dian)(dian)纜(lan)。耐壓(ya)(ya)(ya)等(deng)(deng)級1KV～138KV。4。氣(qi)體絕緣(yuan)電(dian)(dian)纜(lan)。耐壓(ya)(ya)(ya)等(deng)(deng)級220KV～500KV。
低壓絕(jue)緣(yuan)電(dian)(dian)(dian)(dian)纜(lan)適用(yong)(yong)于耐壓450V/750V以(yi)下(xia)的電(dian)(dian)(dian)(dian)氣配(pei)備用(yong)(yong)處極廣分類也許多。一般工業用(yong)(yong)塑料(liao)絕(jue)緣(yuan)電(dian)(dian)(dian)(dian)纜(lan)用(yong)(yong)于固(gu)定敷(fu)設。移動用(yong)(yong)橡(xiang)套低壓絕(jue)緣(yuan)電(dian)(dian)(dian)(dian)纜(lan)。建筑裝置首(shou)要用(yong)(yong)于電(dian)(dian)(dian)(dian)源總電(dian)(dian)(dian)(dian)路、各(ge)干支、分支路的敷(fu)設。也有用(yong)(yong)于電(dian)(dian)(dian)(dian)梯裝置的特種扁形電(dian)(dian)(dian)(dian)梯電(dian)(dian)(dian)(dian)纜(lan)。
