Summary

Due to a serials of innovations over material, technology, and structure, the furnace transformer features small size, light weight, high efficiency, low loss, low noise, reliable operation and large overloading capacity, etc. the transformer generates good economic returns for it could reduce significantly the power grid loss and bring down substantially the long term operational charges. The transformer is designed to apply mostly in metallurgy industry for smelting quality alloy steel and iron alloy and in chemical industry for processing yellow phosphorous, calcium carbide and synthetic resin, etc.

The model of the electric furnace transformer is expressed as follows:
