籍姜急2881多少的线路承受多大电流? -
养征矩15297214710 ______ 线路承受电流的计算方法: 线路承受电流=线路每平米的安全载流量x导线截面积. 一般铜导线的安全载流量为5~8A/mm²,铝导线的安全载流量为3~5A/mm². 例如:2.5mm²BVV铜导线安全载流量的推荐值2.5*8A/mm2=20A. 安全载流量定义: 装置电器设备的线路,一般都用塑料或橡胶绝缘电线.合上开关,电流通过电线进入电器设备,使电器设备工作.由于电气线路本身具有电阻,通过电流时就会发热,产生的热量会通过电线的绝缘层散发到空气中去.如果电线发出去的热量恰好等于电流通过电线产生的热量,电线的温度就不再升高,这时的电流值就是该电线的安全载流量.
