YHD3*10耐寒橡套電纜實用(yong)于交流額(e)外(wai)電壓(ya)500V或直流1000V，野外(wai)條件下利用(yong)，鍍錫(xi)銅(tong)芯，橡(xiang)皮絕緣橡(xiang)皮護套電力電纜。

導體的(de)(de)(de)概念(nian)：即是(shi)能(neng)(neng)(neng)(neng)夠讓電流順利通(tong)過的(de)(de)(de)金屬(shu)載體材料。導體必(bi)須有良好的(de)(de)(de)導電性(xing)(xing)能(neng)(neng)(neng)(neng)、物理機(ji)械(xie)性(xing)(xing)能(neng)(neng)(neng)(neng)、工藝性(xing)(xing)能(neng)(neng)(neng)(neng)和(he)防腐性(xing)(xing)能(neng)(neng)(neng)(neng)。就導電性(xing)(xing)能(neng)(neng)(neng)(neng)來說(shuo)，金屬(shu)依次為(wei)銀、銅(tong)(tong)(tong)(tong)、金、鋁、鎳、鋼(gang)、合金。但是(shi)由于金屬(shu)銀的(de)(de)(de)價(jia)格昂貴，所以我們(men)在電纜當(dang)中多采用(yong)銅(tong)(tong)(tong)(tong)絲，一般在20℃銅(tong)(tong)(tong)(tong)的(de)(de)(de)電阻率(lv)(lv)為(wei) 0.0175 Ω · mm2/m。我們(men)為(wei)了保證導體能(neng)(neng)(neng)(neng)夠充(chong)分的(de)(de)(de)滿足電纜應(ying)有的(de)(de)(de)性(xing)(xing)能(neng)(neng)(neng)(neng)，在電纜導體中我們(men)多選擇無氧銅(tong)(tong)(tong)(tong)。氧的(de)(de)(de)含量不(bu)大于0.03％，雜質(zhi)總(zong)含量不(bu)大于0.05％，銅(tong)(tong)(tong)(tong)的(de)(de)(de)純度大于99.95％的(de)(de)(de)銅(tong)(tong)(tong)(tong)就叫無氧銅(tong)(tong)(tong)(tong) 。無氧銅(tong)(tong)(tong)(tong)無氫脆現象，導電率(lv)(lv)高，加工性(xing)(xing)能(neng)(neng)(neng)(neng)、焊接性(xing)(xing)能(neng)(neng)(neng)(neng)、耐蝕(shi)性(xing)(xing)能(neng)(neng)(neng)(neng)和(he)低(di)溫性(xing)(xing)能(neng)(neng)(neng)(neng)都(dou)非(fei)常的(de)(de)(de)良好

YHD3*10耐寒橡套電纜絕(jue)緣的(de)(de)(de)概念：所謂絕(jue)緣，就是用(yong)絕(jue)緣物質和材(cai)(cai)料(liao)把(ba)帶電(dian)(dian)(dian)體(ti)包住并封(feng)閉起來，以隔離帶電(dian)(dian)(dian)體(ti)或不同電(dian)(dian)(dian)位(wei)的(de)(de)(de)導體(ti)，使電(dian)(dian)(dian)流(liu)按一(yi)定的(de)(de)(de)通(tong)路流(liu)通(tong)。絕(jue)緣橡(xiang)皮必須具有良(liang)好的(de)(de)(de)介電(dian)(dian)(dian)性能、較高(gao)的(de)(de)(de)絕(jue)緣電(dian)(dian)(dian)阻和耐(nai)壓強度、優良(liang)的(de)(de)(de)物理機械性能，并具有一(yi)定的(de)(de)(de)可塑性便于(yu)加工和柔(rou)軟性便于(yu)安裝使用(yong)。橡(xiang)套電(dian)(dian)(dian)纜的(de)(de)(de)絕(jue)緣材(cai)(cai)料(liao)早(zao)期(qi)選用(yong)的(de)(de)(de)材(cai)(cai)料(liao)有天(tian)然膠(NR)、丁苯膠(SBR)、三元乙(yi)丙膠(EPR或EPDM)等(deng)。但(dan)是由(you)于(yu)新標準(zhun)規定絕(jue)緣材(cai)(cai)料(liao)一(yi)定要通(tong)過空氣彈測試，所以現在企(qi)業多用(yong)純(chun)三元乙(yi)丙膠或者氯化聚乙(yi)烯(CPE)與三元乙(yi)丙膠并用(yong)的(de)(de)(de)材(cai)(cai)料(liao)來滿足(zu)標準(zhun)的(de)(de)(de)要求 。
