橡(xiang)(xiang)膠(jiao)線(xian)(xian)(xian)(xian)(xian)也稱橡(xiang)(xiang)膠(jiao)護套線(xian)(xian)(xian)(xian)(xian)，是一種雙絕(jue)緣(yuan)線(xian)(xian)(xian)(xian)(xian)材(cai)；施(shi)工(gong)升降機配件(jian)外皮(pi)與絕(jue)緣(yuan)層(ceng)為(wei)橡(xiang)(xiang)膠(jiao)材(cai)質，導(dao)體為(wei)純銅。在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)(xian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)行業中，絕(jue)緣(yuan)層(ceng)通常(chang)使(shi)用(yong)(yong)(yong)氯化聚乙烯（CPE），承受溫(wen)度為(wei)-40°C~105°C，由其性(xing)能決定(ding)(ding)橡(xiang)(xiang)膠(jiao)線(xian)(xian)(xian)(xian)(xian)只能用(yong)(yong)(yong)于(yu)低壓、低頻的環境中。橡(xiang)(xiang)膠(jiao)線(xian)(xian)(xian)(xian)(xian)又(you)叫(jiao)橡(xiang)(xiang)套軟線(xian)(xian)(xian)(xian)(xian)或(huo)者橡(xiang)(xiang)膠(jiao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源線(xian)(xian)(xian)(xian)(xian)，由于(yu)其耐上下溫(wen)，普遍的應用(yong)(yong)(yong)在(zai)各個范疇。適(shi)用(yong)(yong)(yong)于(yu)交流額定(ding)(ding)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓300V/500V和(he)450/750V及以(yi)下動(dong)力裝(zhuang)置(zhi),家(jia)用(yong)(yong)(yong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器,電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)工(gong)具，施(shi)工(gong)照明和(he)機器里面等要求柔軟或(huo)移(yi)動(dong)場所(suo)，作電(dian)(dian)(dian)(dian)(dian)(dian)(dian)氣連接線(xian)(xian)(xian)(xian)(xian)或(huo)布(bu)線(xian)(xian)(xian)(xian)(xian)。按用(yong)(yong)(yong)途分有(you)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)、控制和(he)信號電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)、船用(yong)(yong)(yong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)、航(hang)空用(yong)(yong)(yong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)、礦山用(yong)(yong)(yong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)、安(an)裝(zhuang)用(yong)(yong)(yong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)(xian)等。

絕(jue)緣(yuan)(yuan)層和護套用(yong)天然橡膠、丁(ding)苯橡膠、乙丙(bing)橡膠等制作，除(chu)了(le)使得絕(jue)緣(yuan)(yuan)性(xing)能(neng)和物理機(ji)械(xie)性(xing)能(neng)外(wai)，要求耐(nai)老化(hua)、好用(yong)，有些產品要求耐(nai)油、阻(zu)燃(ran)。

電線(xian)、電纜一般用擠出成型，連續硫化。產品用于各(ge)行各(ge)業。
