Product Features:

- Low Loss and Low Noise

- Safe and Reliable Operation

- Powerful Name Plate Operating Capacity and Excellent Thermal Performance

- Convenient to Install and Maintain

- Elaborate Operation

- The bell type tank and the corrugated shell increases the strength of tank with beautiful appearance.

- The core and tank are well fixed and well protected during transportation.

- Reasonable winding layout method, supported by the interior and exterior strips. High-tension cardboard cylinders between coils increase the short-circuit withstand capacity.

- Advanced workmanship is used, such as crimp welding technology phase-assembly technology for winding, and cardboard process, etc.

- To meet the client's needs, we can provide products of other voltage ratios, Vector Groups, and rated capacities, as listed in the table.
