UL電子線塑(su)料具(ju)(ju)有(you)可(ke)(ke)(ke)塑(su)性(xing)(xing)，所謂塑(su)料的(de)(de)可(ke)(ke)(ke)塑(su)性(xing)(xing)就是可(ke)(ke)(ke)以經由加熱(re)(re)的(de)(de)方法使固(gu)體(ti)的(de)(de)塑(su)料變軟(ruan)(ruan)，然后再把變軟(ruan)(ruan)了的(de)(de)塑(su)料放在模具(ju)(ju)中，讓它冷卻(que)后又從新凝結成(cheng)必然外形的(de)(de)固(gu)體(ti)。塑(su)料的(de)(de)這種(zhong)性(xing)(xing)質也有(you)必然的(de)(de)缺陷，即(ji)遇熱(re)(re)時輕易軟(ruan)(ruan)化變形，有(you)的(de)(de)塑(su)料以致用(yong)溫度(du)較高(gao)的(de)(de)水(shui)燙一下就會(hui)變形，所以塑(su)料成(cheng)品(pin)通俗(su)不宜接觸開水(shui)。

ul電子線橡膠電線的導體保護層要采用半導電的橡膠材料加工。導體保護層采用圍繞從事生產，UL電子線圍繞編制生產的保護層比繞包編制生產的加倍滑膩沒有崛起，便于均勻電場下場的提升。

ul電子線輻照的過程形成材料的交聯，改變了材料的原始物理機械性能，在抗拉強度隨劑量的升高而升高，達到極限的同時斷裂伸長率隨劑量的升高而明顯下降，老化指標也會因材料交聯度的變化而變化。欠劑量或過劑量都將影響線纜的產品質量，因此要根據不同材料的特性，依據線纜的綜合指標來確定佳的輻照劑量，實現線纜質量的優。

ul電(dian)(dian)子線長(chang)期過負荷運行超負荷運行，由(you)于電(dian)(dian)流(liu)(liu)的(de)熱(re)效應(ying)，負載(zai)電(dian)(dian)流(liu)(liu)通過電(dian)(dian)纜(lan)(lan)時致使(shi)導(dao)體發熱(re)，同時電(dian)(dian)荷的(de)集膚(fu)效應(ying)以及鋼(gang)鎧(kai)的(de)渦流(liu)(liu)損耗、絕(jue)緣(yuan)(yuan)介質損耗也會產乍附加熱(re)量，從(cong)而使(shi)電(dian)(dian)纜(lan)(lan)溫(wen)度升(sheng)高。長(chang)期超負荷運行時，過高的(de)溫(wen)度會加速絕(jue)緣(yuan)(yuan)的(de)老化，以至絕(jue)緣(yuan)(yuan)被擊(ji)穿。尤其在(zai)炎熱(re)的(de)夏季(ji)，電(dian)(dian)纜(lan)(lan)的(de)溫(wen)升(sheng)常(chang)常(chang)致使(shi)電(dian)(dian)纜(lan)(lan)絕(jue)緣(yuan)(yuan)薄(bo)弱處首先被擊(ji)穿，因此(ci)在(zai)夏季(ji)，電(dian)(dian)纜(lan)(lan)的(de)故障也就特別多。

常見的ul電子線有很多，且主要是靠絕緣和護套材料來區分。根據絕緣和護套材料的不同，主要分為PVC電子線/低煙無鹵電子線/硅膠線/鐵氟龍電子線等。ul電子線的成本主要包括銅價成本和膠料成本，所以電子線成本=銅價成本+膠料成本。

ul電(dian)(dian)子線柔性礦物(wu)絕緣電(dian)(dian)纜(lan)(lan)是塑(su)料電(dian)(dian)纜(lan)(lan)性能(neng)優點(dian)的(de)集合，“防(fang)火”僅是其(qi)(qi)一項直(zhi)(zhi)觀表現的(de)性能(neng)。不燃、柔韌、防(fang)爆、防(fang)腐、防(fang)水、防(fang)磁、防(fang)機(ji)械損(sun)傷（包括(kuo)動物(wu)嚙咬）、載(zai)流量(liang)大、過載(zai)能(neng)力強等，任一項性能(neng)的(de)效果均遠優于塑(su)料電(dian)(dian)纜(lan)(lan)。而且具(ju)有(you)十(shi)分好的(de)防(fang)暴性，可(ke)以(yi)阻止蒸汽火焰在(zai)電(dian)(dian)纜(lan)(lan)銜(xian)接(jie)零件之(zhi)間的(de)經過。而且它的(de)直(zhi)(zhi)徑要(yao)比其(qi)(qi)他額外電(dian)(dian)流相(xiang)反的(de)電(dian)(dian)纜(lan)(lan)要(yao)小，還有(you)防(fang)水的(de)作用，特別的(de)鞏固耐用，可(ke)以(yi)經過勐烈(lie)的(de)機(ji)器毀壞(huai)，而不會損(sun)壞(huai)其(qi)(qi)它的(de)電(dian)(dian)功能(neng)。

ul電子線外力損傷。由近幾年的運行分析來看，尤其是在經濟高速發展中，現在相當多的電纜故障都是由于機械損傷引起的電纜接頭故障。電纜接頭是電纜線路中薄弱的環節，由人員直接過失(施工不良)激起的電纜接頭故障時常發生。施工人員在制作電纜接頭過程中，如果有接頭壓接不緊、加熱不充分等原網，所有會致使電纜頭絕緣降低，從而激起事故。
