而且也要(yao)(yao)看電(dian)纜本身是否有商(shang)標、規格、電(dian)壓等。還要(yao)(yao)看電(dian)線(xian)銅(tong)(tong)芯的(de)(de)(de)橫(heng)截(jie)面，的(de)(de)(de)紫銅(tong)(tong)顏(yan)色光亮、色澤柔和。2、稱重(zhong)量。質量好(hao)的(de)(de)(de)電(dian)線(xian)，一般都在規定的(de)(de)(de)重(zhong)量范圍內。比如常用(yong)的(de)(de)(de)截(jie)面積(ji)為(wei)(wei)1。5平(ping)(ping)方的(de)(de)(de)塑(su)料(liao)絕緣單股(gu)銅(tong)(tong)芯線(xian)，每100m重(zhong)量為(wei)(wei)1。8~1。9KG，2。5平(ping)(ping)方的(de)(de)(de)塑(su)料(liao)絕緣單股(gu)銅(tong)(tong)芯線(xian)，每100m的(de)(de)(de)重(zhong)量為(wei)(wei)3~3。1kg。質量差的(de)(de)(de)電(dian)纜重(zhong)量不(bu)足，要(yao)(yao)么(me)長度不(bu)夠(gou)，要(yao)(yao)么(me)電(dian)線(xian)的(de)(de)(de)銅(tong)(tong)芯雜(za)質太多。

遇到電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)(dian)纜(lan)進水(shui)(shui)你是怎么解決的(de)(de)？一(yi)(yi)、電(dian)(dian)(dian)(dian)(dian)纜(lan)里(li)面有水(shui)(shui)的(de)(de)危害。一(yi)(yi)般而言，電(dian)(dian)(dian)(dian)(dian)纜(lan)進水(shui)(shui)后，在(zai)電(dian)(dian)(dian)(dian)(dian)磁場的(de)(de)作用(yong)下會(hui)發(fa)生“水(shui)(shui)樹(shu)老化”現象(xiang)，電(dian)(dian)(dian)(dian)(dian)纜(lan)損壞只會(hui)是時(shi)間(jian)問題，電(dian)(dian)(dian)(dian)(dian)纜(lan)電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)報價，終會(hui)導致電(dian)(dian)(dian)(dian)(dian)纜(lan)擊穿。二(er)、電(dian)(dian)(dian)(dian)(dian)纜(lan)里(li)面有水(shui)(shui)的(de)(de)原因。1，電(dian)(dian)(dian)(dian)(dian)纜(lan)敷(fu)設(she)(she)保存時(shi)，兩端電(dian)(dian)(dian)(dian)(dian)纜(lan)頭并(bing)沒有進行(xing)(xing)密封處理或者密封性不好，水(shui)(shui)汽滲入電(dian)(dian)(dian)(dian)(dian)纜(lan)內部。2，電(dian)(dian)(dian)(dian)(dian)纜(lan)敷(fu)設(she)(she)過(guo)(guo)程(cheng)中(zhong)，電(dian)(dian)(dian)(dian)(dian)纜(lan)頭密封不好且浸(jin)泡在(zai)水(shui)(shui)中(zhong)，或者在(zai)穿管敷(fu)設(she)(she)時(shi)，電(dian)(dian)(dian)(dian)(dian)纜(lan)外絕緣皮，什么牌子的(de)(de)電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)好，水(shui)(shui)滲入電(dian)(dian)(dian)(dian)(dian)纜(lan)。3，電(dian)(dian)(dian)(dian)(dian)纜(lan)敷(fu)設(she)(she)完(wan)成后，兩端的(de)(de)電(dian)(dian)(dian)(dian)(dian)纜(lan)頭沒有及(ji)時(shi)制(zhi)作，長期(qi)暴露在(zai)空氣(qi)中(zhong)或者潮(chao)濕環境中(zhong)。4，電(dian)(dian)(dian)(dian)(dian)纜(lan)供電(dian)(dian)(dian)(dian)(dian)運行(xing)(xing)過(guo)(guo)程(cheng)中(zhong)發(fa)生過(guo)(guo)局部電(dian)(dian)(dian)(dian)(dian)纜(lan)擊穿，宣城電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)，水(shui)(shui)滲入電(dian)(dian)(dian)(dian)(dian)纜(lan)。

如果是(shi)(shi)一(yi)些大型的(de)(de)(de)(de)用(yong)(yong)電(dian)(dian)設備、或是(shi)(shi)用(yong)(yong)電(dian)(dian)環境(jing)，那么在(zai)(zai)電(dian)(dian)力的(de)(de)(de)(de)輸送方面就需(xu)要使(shi)(shi)用(yong)(yong)到(dao)專(zhuan)(zhuan)門(men)的(de)(de)(de)(de)電(dian)(dian)線(xian)電(dian)(dian)纜(lan)，這(zhe)種電(dian)(dian)纜(lan)是(shi)(shi)專(zhuan)(zhuan)門(men)為大型用(yong)(yong)電(dian)(dian)需(xu)求的(de)(de)(de)(de)各類(lei)機械(xie)操作(zuo)(zuo)(zuo)、以及一(yi)些大功率燈(deng)具使(shi)(shi)用(yong)(yong)時所需(xu)要的(de)(de)(de)(de)作(zuo)(zuo)(zuo)用(yong)(yong)而生(sheng)產的(de)(de)(de)(de)，能夠(gou)給操作(zuo)(zuo)(zuo)人(ren)員們(men)(men)(men)帶來(lai)1好的(de)(de)(de)(de)安(an)全(quan)保障。同(tong)時在(zai)(zai)這(zhe)種電(dian)(dian)線(xian)電(dian)(dian)纜(lan)上面也(ye)可(ke)(ke)以進(jin)行多種不同(tong)涂層(ceng)的(de)(de)(de)(de)定(ding)(ding)制(zhi)、高碳鋼或是(shi)(shi)纖維玻璃鋼等等，都(dou)(dou)可(ke)(ke)以根(gen)據用(yong)(yong)戶的(de)(de)(de)(de)需(xu)求來(lai)進(jin)行特別的(de)(de)(de)(de)定(ding)(ding)制(zhi)，這(zhe)就使(shi)(shi)得客(ke)戶們(men)(men)(men)在(zai)(zai)一(yi)些特別環境(jing)中(zhong)的(de)(de)(de)(de)需(xu)求，也(ye)得到(dao)了(le)充分的(de)(de)(de)(de)滿足，讓大家都(dou)(dou)能夠(gou)擁有為出色的(de)(de)(de)(de)享(xiang)受，再者大家可(ke)(ke)以看到(dao)的(de)(de)(de)(de)是(shi)(shi)這(zhe)類(lei)電(dian)(dian)纜(lan)使(shi)(shi)用(yong)(yong)壽命長，而且還堅固(gu)耐用(yong)(yong)，有著非常好的(de)(de)(de)(de)安(an)全(quan)系數，在(zai)(zai)礦(kuang)場(chang)這(zhe)種意外(wai)多發的(de)(de)(de)(de)地段里(li)面，可(ke)(ke)謂就是(shi)(shi)工(gong)作(zuo)(zuo)(zuo)人(ren)員們(men)(men)(men)的(de)(de)(de)(de)一(yi)根(gen)安(an)全(quan)繩了(le)，它的(de)(de)(de)(de)牢固(gu)能夠(gou)讓工(gong)作(zuo)(zuo)(zuo)人(ren)員們(men)(men)(men)享(xiang)受到(dao)一(yi)個為放心的(de)(de)(de)(de)工(gong)作(zuo)(zuo)(zuo)環境(jing)。
