Where can I collect used transformers?

Fair enough, there are second-hand transformers in 58 cities.

Second-hand waste transformer recycling is divided into two categories, one is available and the other is not available. If it can be used, it can be used as a second-hand transformer, so the price will be much higher. Huang Hui Copper specializes in second-hand equipment; Generally, voltage recovery devices on the market are collected according to whether they can be used or not. If it is collected according to waste, it depends on whether the transformer is copper core or aluminum core. The general market price of copper core transformer is about 1.3W/ ton, and that of aluminum core transformer is about 5.5k/ ton.
