江西電纜耐熱和高溫電線電纜的(de)(de)(de)主(zhu)要特點：耐熱和高(gao)(gao)溫(wen)(wen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)一(yi)般是(shi)由兩種需(xu)求(qiu)決定(ding)的(de)(de)(de)。一(yi)種是(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)環境溫(wen)(wen)度較(jiao)高(gao)(gao)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)在(zai)(zai)長(chang)期在(zai)(zai)高(gao)(gao)溫(wen)(wen)下(xia)能(neng)(neng)夠正(zheng)常傳輸信號(hao)或(huo)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)能(neng)(neng);另(ling)一(yi)種是(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力傳輸電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)，主(zhu)要是(shi)增加截流(liu)能(neng)(neng)力為(wei)主(zhu)要目的(de)(de)(de)。高(gao)(gao)溫(wen)(wen)環境下(xia)工作(zuo)(zuo)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)。普(pu)通電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)在(zai)(zai)高(gao)(gao)溫(wen)(wen)時易產生絕緣老化和焦燒現象，使(shi)(shi)用電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)失去性能(neng)(neng)，受破壞而(er)不(bu)能(neng)(neng)使(shi)(shi)用。高(gao)(gao)溫(wen)(wen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)在(zai)(zai)額定(ding)高(gao)(gao)溫(wen)(wen)下(xia)能(neng)(neng)夠正(zheng)常穩定(ding)地工作(zuo)(zuo)，信號(hao)或(huo)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)能(neng)(neng)傳輸性能(neng)(neng)不(bu)受影(ying)響，還能(neng)(neng)保(bao)(bao)證電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)具有較(jiao)長(chang)的(de)(de)(de)使(shi)(shi)用壽命。這類功能(neng)(neng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)是(shi)高(gao)(gao)溫(wen)(wen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)常見(jian)的(de)(de)(de)一(yi)種，使(shi)(shi)用特性也(ye)易于理解的(de)(de)(de)。增載型高(gao)(gao)溫(wen)(wen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)，主(zhu)要是(shi)為(wei)了保(bao)(bao)證載流(liu)的(de)(de)(de)前題下(xia)減(jian)小電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)外徑(jing)和重(zhong)量(liang)，向輕量(liang)化發展的(de)(de)(de)。

一般來(lai)說，電(dian)(dian)纜(lan)的(de)(de)工作(zuo)溫(wen)度越(yue)高，同(tong)樣截(jie)面的(de)(de)電(dian)(dian)纜(lan)通過的(de)(de)載流量(liang)(liang)越(yue)大(da)。就(jiu)像飛(fei)機和汽車等場合，減輕重量(liang)(liang)的(de)(de)意義相當(dang)大(da)，利用高溫(wen)電(dian)(dian)纜(lan)大(da)大(da)減少了截(jie)面。工作(zuo)溫(wen)度從90℃升到155℃，則載流能力(li)上升50%，同(tong)樣載流量(liang)(liang)下，電(dian)(dian)纜(lan)重量(liang)(liang)要減輕一半(ban)，成本也(ye)有所(suo)降低(di)。當(dang)然高截(jie)流的(de)(de)同(tong)時，大(da)多(duo)數絕緣材料的(de)(de)電(dian)(dian)能損耗也(ye)會有所(suo)增加(jia)。

江(jiang)西電(dian)(dian)纜(lan)耐(nai)(nai)(nai)熱(re)(re)型電(dian)(dian)線電(dian)(dian)纜(lan)分：耐(nai)(nai)(nai)熱(re)(re)材(cai)(cai)料(liao)(liao)(liao)和普通材(cai)(cai)料(liao)(liao)(liao)的(de)(de)耐(nai)(nai)(nai)熱(re)(re)改性(xing)兩種(zhong)。 　　(一(yi))耐(nai)(nai)(nai)熱(re)(re)材(cai)(cai)料(liao)(liao)(liao)的(de)(de)電(dian)(dian)線電(dian)(dian)纜(lan) 　　耐(nai)(nai)(nai)熱(re)(re)材(cai)(cai)料(liao)(liao)(liao)的(de)(de)電(dian)(dian)線電(dian)(dian)纜(lan)是(shi)絕緣和護套(tao)(tao)材(cai)(cai)料(liao)(liao)(liao)本體樹(shu)脂(zhi)具有耐(nai)(nai)(nai)熱(re)(re)性(xing)能，主要品種(zhong)有：聚(ju)氨脂(zhi)(可達(da)155℃級)、聚(ju)脂(zhi)(可達(da)135℃)、聚(ju)偏氟乙(yi)烯(xi)(150℃)和尼龍(可達(da)115℃)的(de)(de)絕緣或護套(tao)(tao)材(cai)(cai)料(liao)(liao)(liao)。常用于通信、汽車(che)、電(dian)(dian)機、建(jian)筑等行業。
