Taking the data of transformer s 13 copper core (model 19, model 20) as an example, it is found that the total weight is 293kg, the copper output is 50Kg, 50Kv, the total weight is 408kg, and the copper output is 6 1kg, 80Kv.
The copper output of waste transformers is relatively large, much more than that of ordinary motors, so the recycling price of waste transformers is high.
