   连之新采购的电源线是直接从厂家购买的,通常足量标称的电源线3*3*0.75,三条线,每条线里有44根铜线 0.14的直径,完成直径是6.16.是标准的国标电源线,这种电源线耐压,耐摇摆,不容易折断,不会短路过载,符合3C标准。而市场购买的零售电源线通常是数量不足的,我这里有一条客户寄来的市场电源线测量的结果是23*0.18,完成直径只有4.14,线是稍微粗了点,但是线少很多了,摇摆容易折断,但是价格会更低廉,市场上购买的零售电源线基本都是这个样子的,更差的电源线是铜包铝或者铜包铁的,可通过燃烧试验和加大电流进行测试,如果燃烧电源线单丝很容易就烧断的,是铜包铝线。如果线很粗,加大电流电源线发热的是铜包铁电源线。
