今天金環宇電線電纜小編帶給大家的(de)內(nei)容是介紹如何區分高壓和低壓電線電纜(lan):
一:查看截面(mian)電纜(lan)最內的部(bu)分為到(dao)電芯
一(yi)次(ci)往外面(mian)(mian)是(shi)絕緣層(ceng)半導電(dian)層(ceng),屏蔽層(ceng)和填(tian)充(chong)層(ceng)。現在市(shi)場上面(mian)(mian)有(you)(you)很多的(de)(de)商(shang)(shang)家都會采用劣質的(de)(de)物品來進(jin)行冒充(chong),如果使用一(yi)些不合(he)格(ge)的(de)(de)產品為(wei)(wei)電(dian)纜(lan)進(jin)行填(tian)充(chong),有(you)(you)的(de)(de)是(shi)未來更多的(de)(de)利益(yi),但是(shi)有(you)(you)一(yi)部分為(wei)(wei)了(le)試探(tan)市(shi)場,為(wei)(wei)了(le)以后可以很好的(de)(de)投機,增(zeng)大商(shang)(shang)人的(de)(de)利益(yi),擴(kuo)展利潤圈的(de)(de)來源。
一(yi)般低(di)壓(ya)電(dian)纜的(de)(de)(de)絕緣層厚度是很薄的(de)(de)(de),低(di)壓(ya)大概(gai)是1—3高壓(ya)大概(gai)是較低(di)壓(ya)的(de)(de)(de)厚度要(yao)高的(de)(de)(de),他(ta)的(de)(de)(de)受壓(ya)力更高,也就(jiu)是說他(ta)的(de)(de)(de)抗(kang)壓(ya)力要(yao)不小(xiao)于低(di)壓(ya)電(dian)纜,低(di)壓(ya)電(dian)纜不容(rong)易發熱,因(yin)此不容(rong)易發生起火的(de)(de)(de)現(xian)象,對于高壓(ya)電(dian)纜來講,這就(jiu)是一(yi)個很大的(de)(de)(de)弊端,低(di)壓(ya)電(dian)纜是只(zhi)有(you)一(yi)層保護(hu)套。
三:如何區分高壓與低壓電力電纜
高壓電纜去(qu)除外(wai)(wai)皮之后具有(you)絕緣層,就(jiu)是(shi)包裹在(zai)電纜芯的外(wai)(wai)面,白色的像是(shi)塑料(liao)的主(zhu)要絕緣層,低壓電纜是(shi)沒有(you)這(zhe)一個重要的絕緣保護層的,他的耐抗性很差,白色的像是(shi)塑料(liao)的主(zhu)要絕緣層,低壓電纜主(zhu)要是(shi)沒有(you)這(zhe)個主(zhu)絕緣層。
電(dian)(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)是(shi)用于(yu)傳(chuan)輸和分(fen)配電(dian)(dian)(dian)(dian)(dian)能的(de)電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan),電(dian)(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)長(chang)用于(yu)城(cheng)市(shi)的(de)地下(xia)電(dian)(dian)(dian)(dian)(dian)網(wang),工礦企業內部供(gong)電(dian)(dian)(dian)(dian)(dian)以(yi)及(ji)過(guo)江(jiang)海(hai)水的(de)輸電(dian)(dian)(dian)(dian)(dian)線,電(dian)(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)中,電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)所占的(de)比重正在增加(jia),電(dian)(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)是(shi)電(dian)(dian)(dian)(dian)(dian)力系統(tong)在主要干線上的(de)用以(yi)傳(chuan)輸和分(fen)配的(de)大功率電(dian)(dian)(dian)(dian)(dian)能的(de)電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)產品。
高壓(ya)電纜在(zai)安裝時(shi)同樣需要接地,目的(de)(de)是(shi)(shi)為(wei)了便于檢測電纜內護(hu)層的(de)(de)好(hao)壞,在(zai)檢測電纜的(de)(de)保護(hu)層時(shi),鋼鎧(kai)與(yu)銅屏(ping)蔽通上電纜,如(ru)果可(ke)以承受的(de)(de)電壓(ya)就是(shi)(shi)為(wei)了證明內護(hu)層是(shi)(shi)完好(hao)無(wu)損的(de)(de)。
他的(de)接(jie)地方式是護(hu)套(tao)(tao)一端(duan)直(zhi)接(jie)接(jie)地,另一端(duan)是通過保護(hu)層的(de)保護(hu)接(jie)地,護(hu)套(tao)(tao)的(de)兩(liang)端(duan)接(jie)地這一種方法使用的(de)較少(shao),僅僅適合使用在較短和(he)小(xiao)負(fu)荷(he)的(de)電(dian)纜(lan)線(xian)路(lu)。
