施工人員在(zai)制作(zuo)電(dian)(dian)(dian)纜(lan)(lan)(lan)接(jie)(jie)頭(tou)(tou)過(guo)程中(zhong)，如果有接(jie)(jie)頭(tou)(tou)壓接(jie)(jie)不緊、加熱不充分等原網，都會(hui)導(dao)致電(dian)(dian)(dian)纜(lan)(lan)(lan)頭(tou)(tou)絕緣(yuan)降(jiang)低(di)，從而引發事故(gu)。4、絕緣(yuan)受(shou)潮。這種情況(kuang)也很常見，一般(ban)發生在(zai)直(zhi)埋(mai)或(huo)排管里(li)的電(dian)(dian)(dian)纜(lan)(lan)(lan)接(jie)(jie)頭(tou)(tou)處。比(bi)如：電(dian)(dian)(dian)纜(lan)(lan)(lan)接(jie)(jie)頭(tou)(tou)制作(zuo)不合格(ge)和在(zai)潮濕的氣候條件下(xia)做接(jie)(jie)頭(tou)(tou)，會(hui)使(shi)接(jie)(jie)頭(tou)(tou)進水或(huo)混入水蒸氣，時間(jian)久了在(zai)電(dian)(dian)(dian)場作(zuo)用下(xia)形成水樹枝，逐漸損害電(dian)(dian)(dian)纜(lan)(lan)(lan)的絕緣(yuan)強(qiang)度(du)而造(zao)成故(gu)障(zhang)。5、環(huan)境和溫(wen)度(du)。電(dian)(dian)(dian)纜(lan)(lan)(lan)所(suo)處的外(wai)界環(huan)境和溫(wen)度(du)會(hui)造(zao)成電(dian)(dian)(dian)纜(lan)(lan)(lan)溫(wen)度(du)過(guo)高、絕緣(yuan)擊穿，甚至爆(bao)1炸(zha)起火。6、化學(xue)腐蝕(shi)(shi)。電(dian)(dian)(dian)纜(lan)(lan)(lan)直(zhi)接(jie)(jie)埋(mai)在(zai)有酸堿作(zuo)用的地區，往(wang)往(wang)會(hui)造(zao)成電(dian)(dian)(dian)纜(lan)(lan)(lan)的鎧(kai)裝、鉛皮或(huo)外(wai)護(hu)層被腐蝕(shi)(shi)，保護(hu)層因長期遭受(shou)化學(xue)腐蝕(shi)(shi)或(huo)電(dian)(dian)(dian)解腐蝕(shi)(shi)，致使(shi)保護(hu)層失效，絕緣(yuan)降(jiang)低(di)，也會(hui)導(dao)致電(dian)(dian)(dian)纜(lan)(lan)(lan)故(gu)障(zhang)。

電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)和(he)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)有區別嗎？電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)是指(zhi)用(yong)(yong)于(yu)(yu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)力、通信(xin)(xin)及相關傳輸用(yong)(yong)途的(de)材料。“電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)”和(he)“電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)”并(bing)沒有嚴格(ge)的(de)界限。通常將芯(xin)數少、產品直徑(jing)小、結構簡單(dan)的(de)產品稱(cheng)為(wei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)，沒有絕(jue)緣(yuan)的(de)稱(cheng)為(wei)裸電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)，其他的(de)稱(cheng)為(wei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan);導體截面積較大(da)的(de)(大(da)于(yu)(yu)6平(ping)方毫(hao)米(mi)(mi))稱(cheng)為(wei)大(da)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)，較小的(de)(小于(yu)(yu)或等(deng)于(yu)(yu)6平(ping)方毫(hao)米(mi)(mi))稱(cheng)為(wei)小電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)，綠寶(bao)礦用(yong)(yong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)廠家，絕(jue)緣(yuan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)又稱(cheng)為(wei)布電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)。電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)主要(yao)包括(kuo)(kuo)裸線(xian)(xian)(xian)(xian)、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)磁線(xian)(xian)(xian)(xian)及電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器用(yong)(yong)絕(jue)緣(yuan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)、通信(xin)(xin)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)與(yu)光纜(lan)(lan)。電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)主要(yao)包括(kuo)(kuo)裸線(xian)(xian)(xian)(xian)、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)磁線(xian)(xian)(xian)(xian)及電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器用(yong)(yong)絕(jue)緣(yuan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)、通信(xin)(xin)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)與(yu)光纜(lan)(lan)。

我們知道現在生(sheng)活(huo)離(li)不(bu)(bu)開電(dian)(dian)當(dang)然就離(li)不(bu)(bu)開電(dian)(dian)線(xian)(xian)電(dian)(dian)纜(lan)(lan)(lan)，由于使用(yong)場(chang)合的(de)(de)(de)不(bu)(bu)同對(dui)于電(dian)(dian)線(xian)(xian)電(dian)(dian)纜(lan)(lan)(lan)的(de)(de)(de)選用(yong)也是有(you)區別的(de)(de)(de)，高(gao)(gao)壓電(dian)(dian)纜(lan)(lan)(lan)，變頻電(dian)(dian)纜(lan)(lan)(lan)，阻燃電(dian)(dian)纜(lan)(lan)(lan)等等，這(zhe)些不(bu)(bu)同特性的(de)(de)(de)電(dian)(dian)纜(lan)(lan)(lan)應用(yong)場(chang)所(suo)(suo)有(you)所(suo)(suo)不(bu)(bu)同。電(dian)(dian)線(xian)(xian)電(dian)(dian)纜(lan)(lan)(lan)的(de)(de)(de)品種非(fei)常多，性能要(yao)(yao)求特別高(gao)(gao)，如(ru)導體(ti)用(yong)銅(tong)(tong)，要(yao)(yao)求銅(tong)(tong)的(de)(de)(de)純度要(yao)(yao)在99。95%以上，有(you)的(de)(de)(de)產品要(yao)(yao)采用(yong)無氧(yang)高(gao)(gao)純銅(tong)(tong)。我們對(dui)于電(dian)(dian)線(xian)(xian)電(dian)(dian)纜(lan)(lan)(lan)的(de)(de)(de)挑選非(fei)常的(de)(de)(de)嚴(yan)謹，因為(wei)如(ru)果稍微不(bu)(bu)慎可能會造成安(an)全事故。所(suo)(suo)以一旦電(dian)(dian)線(xian)(xian)電(dian)(dian)纜(lan)(lan)(lan)出現什么異常，一定要(yao)(yao)及時(shi)的(de)(de)(de)找出原因并解決。
