What is the difference between the aluminum wire and the copper wire? Detailed point!
As for the loss and temperature rise, this is not too good evaluation which is more better, because with the cost, such as increasing wire diameter, increase core loss and temperature rise will be smaller, but the cost will go up, this related to the design of each manufacturer, not evaluate ~
It will last longer than the copper line -- and it will be longer. We are at present many domestic manufacturers of aluminum ballast life live shorter than copper wire of the ballast is largely because the production process control, especially aluminium wire connection or welding process is not good enough.
The line size selection is different because the conductor resistance of copper and aluminum leads to different lines in the production of the same performance ballast. 3. Copper wire and aluminum wire products heat resistant performance is not the same, some people might think of aluminium wire heat resistance than copper wire, and the fact of aluminium wire heat resistance than copper wire, ability more high temperature;
The product type is different, the copper wire used in the ballast is mainly 180 levels of polyester, and even some manufacturers will use 155 grade polyester. The aluminium wire used in the ballast is essentially the aluminium wire of the 220-grade polyamide composite polyamide. The main reason is that the 220-grade aluminium line is on the market, and there is a fear that the aluminium line at the 180 level will not meet the ballast performance requirements.
