PVC電(dian)(dian)(dian)(dian)(dian)(dian)纜料(liao)(liao)(liao)是由聚氯(lv)乙烯樹脂、穩定劑(ji)(ji)、增塑劑(ji)(ji)、填充(chong)劑(ji)(ji)、潤(run)滑劑(ji)(ji)、抗氧劑(ji)(ji)、著色劑(ji)(ji)等(deng)組成。PVC電(dian)(dian)(dian)(dian)(dian)(dian)纜料(liao)(liao)(liao)的耐(nai)(nai)電(dian)(dian)(dian)(dian)(dian)(dian)壓和(he)絕(jue)緣電(dian)(dian)(dian)(dian)(dian)(dian)阻比較(jiao)高(gao)(gao)，但介電(dian)(dian)(dian)(dian)(dian)(dian)常(chang)數和(he)介電(dian)(dian)(dian)(dian)(dian)(dian)損耗較(jiao)大。因此(ci)，一(yi)般主要(yao)(yao)用(yong)(yong)作(zuo)低(di)壓（≤1KV）和(he)中高(gao)(gao)壓（6~10KV）電(dian)(dian)(dian)(dian)(dian)(dian)纜的絕(jue)緣層(ceng)。PVC塑料(liao)(liao)(liao)由于具有難燃、耐(nai)(nai)油、耐(nai)(nai)電(dian)(dian)(dian)(dian)(dian)(dian)暈、耐(nai)(nai)化(hua)學腐(fu)蝕和(he)良好的耐(nai)(nai)水性(xing)(xing)(xing)能，因此(ci)還廣泛用(yong)(yong)作(zuo)電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)(dian)(dian)纜的護(hu)層(ceng)材料(liao)(liao)(liao)。利用(yong)(yong)添加特(te)種(zhong)性(xing)(xing)(xing)能助(zhu)劑(ji)(ji)或改性(xing)(xing)(xing)劑(ji)(ji)，可(ke)以分別(bie)制造出耐(nai)(nai)熱(re)型(xing)（105℃）、耐(nai)(nai)寒型(xing)、耐(nai)(nai)油型(xing)、難燃型(xing)、特(te)軟型(xing)和(he)無毒型(xing)的PVC電(dian)(dian)(dian)(dian)(dian)(dian)纜料(liao)(liao)(liao)，以滿足特(te)殊電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)(dian)(dian)纜產品(pin)的需要(yao)(yao)。 電(dian)(dian)(dian)(dian)(dian)(dian)纜料(liao)(liao)(liao)在(zai)PVC配(pei)方中屬于性(xing)(xing)(xing)能要(yao)(yao)求較(jiao)高(gao)(gao)的品(pin)種(zhong)，特(te)別(bie)是電(dian)(dian)(dian)(dian)(dian)(dian)絕(jue)緣性(xing)(xing)(xing)、耐(nai)(nai)低(di)溫性(xing)(xing)(xing)和(he)耐(nai)(nai)老化(hua)性(xing)(xing)(xing)等(deng)都有一(yi)定要(yao)(yao)求。配(pei)方設計時必須考慮這些特(te)殊的要(yao)(yao)求。 PVC電(dian)(dian)(dian)(dian)(dian)(dian)纜料(liao)(liao)(liao)可(ke)分為護(hu)層(ceng)級和(he)絕(jue)緣級兩種(zhong)。護(hu)層(ceng)級要(yao)(yao)求耐(nai)(nai)熱(re)性(xing)(xing)(xing)好，而絕(jue)緣級則要(yao)(yao)求絕(jue)緣性(xing)(xing)(xing)好。?
