Product Features

1. Short circuit strength is very strong
   - It is structurally strong against short-circuiting as well external impact. The epoxy resin which has good electric and mechanical strength is cast for the coil in a vacuum.
2. Impulse voltage strength is good
   - The impulse voltage strength is good due to the epoxy resin insulation effect and to the split coil design method.
3. Fire resistance is good
   - Highly fire resistant epoxy resin is used, this assists in reducing the risk of fire from an electric arc. It is strongly resistant against fire because it has self-extinguishing properties.
4. Moisture proof is good
   - The Epoxy resin coil helps enhance the insulation strength, and assists in shutting out external moisture.
5. Overload capability is great
   - The temperature time constant of the winding is designed in a large scale, compared with oil type transformers, the product can be used in an overload condition without problems.
6. Suitable for power supply to a facility that has severe variations in load
   - Suitable for hugely variable loads, such as a facility for supplying power to Subways or a Rolling Mill facility.
7. Eco-friendly
   - There is no risk of environmental pollution due to leak of oil as no oil is used.
8. Easy maintenance
   - There is no need to replace oil and fire fighting facilities, compared with oil type transformers.
