Copper wound transformer coil with the following advantages:
1, insulation material and the copper conductor close to the expansion coefficient
2, copper conductivity, thermal conductivity, good heat dissipation
3, short high intensity (high melting point of copper)
4, added to the stress of insulation material on the minimum (pure copper is easy bending)
5, high utilization ratio
6, easy welding
7, winding coil, the winding insulation and copper at the same time easy to operate, less time, high efficiency, low labor costs
