80 of the 500 kg oil-immersed transformer out of copper rate is how much

80 of the 500 kilograms of oil-immersed transformers out of copper rate is 40%. Most of the transformer is copper, the rest is cooling oil and iron. That is to say 500 pounds of transformer only about 200 kilograms of copper. The weight of copper content is 30% of the total weight of the transformer. Transformer is the use of the principle of electromagnetic induction to change the AC voltage device, the main components are the primary coil, secondary coil and core. The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization and so on.
