電子線是電線電纜產品中為常用的品種，也稱之為電子線材，通電性主要是以弱電為主。只要應用于電子、電器、設備內部的連接線，UL電子線是常用的電子線材系列，型號多。UL1007與UL1015為常(chang)見(jian)，很多客(ke)戶都會使用到這兩款(kuan)線材。下(xia)面(mian)就(jiu)來了解一下(xia)他們(men)之(zhi)間的共(gong)同點與不(bu)同之(zhi)處。

共(gong)同(tong)處(chu)：首先這(zhe)兩(liang)款(kuan)(kuan)線材(cai)都屬于pvc（聚氯乙烯）電(dian)子線，絕緣采用(yong)(yong)的(de)(de)(de)(de)是(shi)PVC材(cai)料，PVC是(shi)非常(chang)常(chang)用(yong)(yong)的(de)(de)(de)(de)通用(yong)(yong)塑料，應用(yong)(yong)廣泛，在各(ge)行各(ge)業都有(you)(you)很大的(de)(de)(de)(de)需求及(ji)作(zuo)(zuo)用(yong)(yong)。PVC具有(you)(you)著(zhu)色性(xing)(xing)、遷(qian)移(yi)性(xing)(xing)、耐(nai)(nai)(nai)候(hou)性(xing)(xing)、穩定(ding)(ding)性(xing)(xing)、電(dian)性(xing)(xing)能(neng)等，這(zhe)也(ye)是(shi)這(zhe)兩(liang)款(kuan)(kuan)線材(cai)具備的(de)(de)(de)(de)特性(xing)(xing)，導體可以選用(yong)(yong)單支或者絞(jiao)合(he)的(de)(de)(de)(de)鍍錫(xi)銅(tong)絲或者裸銅(tong)絲。大部分(fen)用(yong)(yong)戶會選用(yong)(yong)鍍錫(xi)銅(tong)絲，鍍錫(xi)銅(tong)絲具有(you)(you)抗(kang)氧化的(de)(de)(de)(de)作(zuo)(zuo)用(yong)(yong)。不(bu)同(tong)處(chu)：UL1007:耐(nai)(nai)(nai)溫(wen)80℃，額定(ding)(ding)電(dian)壓(ya)(ya)300V，導體大小由(you)30~16AWG；UL1015：耐(nai)(nai)(nai)溫(wen)105℃，額定(ding)(ding)電(dian)壓(ya)(ya)600V，導體大小有(you)(you)30~4/0 AWG；因此(ci)可以看(kan)出這(zhe)兩(liang)款(kuan)(kuan)電(dian)子線材(cai)的(de)(de)(de)(de)耐(nai)(nai)(nai)溫(wen)有(you)(you)所不(bu)同(tong)，UL1015偏(pian)向(xiang)耐(nai)(nai)(nai)高溫(wen)，而1007則屬于常(chang)規PVC的(de)(de)(de)(de)耐(nai)(nai)(nai)溫(wen)。并且在耐(nai)(nai)(nai)壓(ya)(ya)方面也(ye)是(shi)不(bu)一樣(yang)的(de)(de)(de)(de)。
