ul電子線的優點：

ul電(dian)(dian)(dian)(dian)(dian)子(zi)線(xian)長期過負荷運(yun)轉(zhuan)超負荷運(yun)轉(zhuan)，因(yin)為電(dian)(dian)(dian)(dian)(dian)流的(de)(de)(de)熱效應，負載電(dian)(dian)(dian)(dian)(dian)流通過電(dian)(dian)(dian)(dian)(dian)纜(lan)時(shi)一定致使(shi)(shi)導體發(fa)熱，同(tong)時(shi)電(dian)(dian)(dian)(dian)(dian)荷的(de)(de)(de)集膚效應以(yi)及鋼鎧的(de)(de)(de)渦流損耗、絕緣(yuan)(yuan)介質(zhi)損耗也會(hui)產乍附加(jia)熱量，從(cong)而(er)使(shi)(shi)電(dian)(dian)(dian)(dian)(dian)纜(lan)溫度升高。長期超負荷運(yun)轉(zhuan)時(shi)，過高的(de)(de)(de)溫度會(hui)加(jia)快絕緣(yuan)(yuan)的(de)(de)(de)老化，以(yi)致絕緣(yuan)(yuan)被擊穿。尤其(qi)在炎(yan)熱的(de)(de)(de)夏日，電(dian)(dian)(dian)(dian)(dian)纜(lan)的(de)(de)(de)溫升常(chang)常(chang)致使(shi)(shi)電(dian)(dian)(dian)(dian)(dian)纜(lan)絕緣(yuan)(yuan)單(dan)薄處首(shou)要(yao)被擊穿，因(yin)此(ci)在夏日，電(dian)(dian)(dian)(dian)(dian)纜(lan)的(de)(de)(de)毛病(bing)也就特(te)別多。常(chang)見的(de)(de)(de)ul電(dian)(dian)(dian)(dian)(dian)子(zi)線(xian)有很多，且(qie)首(shou)要(yao)是靠絕緣(yuan)(yuan)和護(hu)套資料(liao)來區別。依據絕緣(yuan)(yuan)和護(hu)套資料(liao)的(de)(de)(de)不同(tong)，首(shou)要(yao)分為PVC電(dian)(dian)(dian)(dian)(dian)子(zi)線(xian)/低煙(yan)無(wu)鹵電(dian)(dian)(dian)(dian)(dian)子(zi)線(xian)/硅膠線(xian)/鐵氟龍(long)電(dian)(dian)(dian)(dian)(dian)子(zi)線(xian)等。ul電(dian)(dian)(dian)(dian)(dian)子(zi)線(xian)的(de)(de)(de)本(ben)(ben)錢(qian)(qian)首(shou)要(yao)包括(kuo)銅(tong)價(jia)本(ben)(ben)錢(qian)(qian)和膠料(liao)本(ben)(ben)錢(qian)(qian)，所以(yi)電(dian)(dian)(dian)(dian)(dian)子(zi)線(xian)本(ben)(ben)錢(qian)(qian)=銅(tong)價(jia)本(ben)(ben)錢(qian)(qian)+膠料(liao)本(ben)(ben)錢(qian)(qian)。

ul電(dian)子線柔性(xing)礦物絕緣電(dian)纜是(shi)塑(su)料(liao)電(dian)纜功(gong)(gong)用優點的調集(ji)，“防(fang)(fang)火”僅是(shi)其(qi)一(yi)項直(zhi)觀表現(xian)的功(gong)(gong)用。不(bu)燃、柔韌(ren)、防(fang)(fang)爆、防(fang)(fang)腐、防(fang)(fang)水(shui)、防(fang)(fang)磁(ci)、防(fang)(fang)機(ji)械損(sun)傷（包括動物嚙咬）、載(zai)流(liu)量大、過(guo)載(zai)能(neng)力強(qiang)等，任一(yi)項功(gong)(gong)用的效果均遠優于(yu)塑(su)料(liao)電(dian)纜。并且具(ju)有十分好的防(fang)(fang)暴性(xing)，能(neng)夠阻止蒸汽火焰在電(dian)纜聯接(jie)零件之(zhi)間的通過(guo)。并且它(ta)的直(zhi)徑要比其(qi)他額定電(dian)流(liu)相(xiang)反(fan)的電(dian)纜要小，還有防(fang)(fang)水(shui)的作用，特別的鞏固耐用，能(neng)夠通過(guo)勐烈的機(ji)器破(po)壞，而(er)不(bu)會損(sun)壞其(qi)它(ta)的電(dian)功(gong)(gong)用。

ul電(dian)(dian)子線(xian)外力損(sun)傷。由(you)近幾年(nian)的(de)(de)運轉剖析來看，尤其是(shi)(shi)(shi)在(zai)經(jing)濟高速發展中，現(xian)在(zai)相當多的(de)(de)電(dian)(dian)纜毛(mao)病都(dou)是(shi)(shi)(shi)因為機械損(sun)傷引起(qi)的(de)(de)電(dian)(dian)纜接(jie)頭毛(mao)病。電(dian)(dian)纜接(jie)頭是(shi)(shi)(shi)電(dian)(dian)纜線(xian)路中單薄的(de)(de)環節(jie)，由(you)人員直(zhi)接(jie)過(guo)錯(施工不良(liang))激起(qi)的(de)(de)電(dian)(dian)纜接(jie)頭毛(mao)病時常產(chan)生。施工人員在(zai)制作(zuo)電(dian)(dian)纜接(jie)頭過(guo)程中，如果(guo)有(you)接(jie)頭壓接(jie)不緊、加熱不充分等原網，所有(you)會致使電(dian)(dian)纜頭絕緣下(xia)降，從而激起(qi)事故(gu)。
