Transformer copper content> 99.95%. Not allowed to contain scale, oil, coating, paint and other impurities. Do not contain wool, 

car, debris and thickness <1mm copper. The advantages and disadvantages of the transformer can be divided into copper transformer 

and half-copper transformer, the transformer coil to determine their own loss of size, the greater the loss of their own 

output power less, so the use of copper is the best.
