  • 銅芯電纜對比(bi)鋁芯電纜的幾點優勢(shi)？

    銅芯電纜(lan)對比(bi)鋁芯電纜(lan)的(de)幾(ji)點優勢？1.電阻率(lv)低：鋁芯電纜(lan)的(de)電阻率(lv)比(bi)銅芯電纜(lan)約高(gao)(gao)1.68倍。2.延展(zhan)性好：銅合金的(de)延展(zhan)率(lv)為20~40%,電工(gong)用銅的(de)延展(zhan)率(lv)在(zai)30%以上(shang)，而鋁合金僅為18%。3.強度高(gao)(gao)：常(chang)溫(wen)(wen)下的(de)允許應(ying)(ying)力，銅比(bi)鋁分別高(gao)(gao)出7~28%。特別是高(gao)(gao)溫(wen)(wen)下的(de)應(ying)(ying)力，兩者相差(cha)更是甚(shen)遠。4.抗疲勞：鋁材反復折彎易(yi)(yi)斷裂，銅則不易(yi)(yi)。彈性指(zhi)標方面，銅也比(bi)鋁高(gao)(gao)約1.7~1.8倍。5.穩定性好，耐腐蝕：銅芯抗氧化，耐腐
