The price of a good transformer is definitely higher than that of a waste transformer, especially on an aluminum core transformer. The price advantages of good and bad transformers are very obvious.
The weight of an S9-3 15 transformer is 265/ 940/ total weight 1390kg. It is unclear what the conductor material of the transformer is.
Although the density of aluminum material is lower than that of copper material, the specifications of transformer aluminum material with the same parameters will be much larger than that of copper material, which will lead to the increase of transformer core weight.
In case of uncertainty, the transformer needs to be turned on. There is a pungent smell when it is opened, which proves that the inner core of the transformer has been burnt, indicating that it is broken.
The price of such a set has to be determined according to the standard of scrapping, which is about 6000 yuan. On the contrary, if there is no smell after opening, it is proved to be good.
The recycling price of such a transformer is around 9000 yuan. If it is a copper core transformer, the price difference between good and bad is within the range of 1000 yuan.
