2.绝缘颜色：3.3线芯为一根红色一根蓝色，0.85线芯为一根白色一根绿色，白色线芯外绕包一层铝箔。3.绝缘厚度：3.3线芯绝缘厚度为0.5，绝缘后外径为3.5毫米。0.85线芯绝缘厚度为0.7绝缘后外径为2.5毫米。
即50mm、70mm导线的载流量为截面数的3倍；95mm、120mm导线载流量是其截面积的5倍，依次类推。"条件有变加折算，高温九折铜升级"：这个口诀指的是铝芯线载流量的计算方法，明敷在环境温度25℃的条件下。版权所有。若环境温度长期高于25℃，按此口诀计算方法算出载流量，然后打九折，比如：2.5mm的铝线，2.5×9=22.5A，打九折，22.5×0.9=20.25A。如果是铜芯电缆，它的载流量计算按铝线规格升一级计算，比如：4mm的铜线，按6mm铝线计算，16mm铜线按25mm铝线计算。
