Patent technical innovation point 1
Coils
Special design of exciting coil, there are the gaps among the winding coils which supply the cooling oil conduit. Increase the scatter area and oil-cooling conduit. Quick heat exchanging. Coil temperature rise is no more than 30 ℃, low temperature rising in cold and hot state, magnetic field difference is small, compare with the same magnetic field strength, the excitation power reduction 20%, saving electricity 45000 KWh/ year.
Fully sealed structure, dust proof, moisture proof, high temperature resistant, it can operate in harsh environment.

Cooling system
1. Cooling system adopts fully sealed outer circulating structure, rain-proof, dust-proof, anticorrosion, suits for all kinds of harsh environment.
2. Adopt air cooling condenser, intelligent control, excitation coil temperature is constant, magnetic field fluctuation minimum (less than 2%)of cooling mode, other domestic manufacturers makes coil temperature is too high, magnetic field fluctuation reach15%~30%, which have great influence to ore dressing indexes.

3. With large flow disc transformer oil pump, fast circulation speed, quick heat exchange.
