66kV electrical transformer

The bell type tank and the corrugated shell increases the strength of the tank and gives it a pleasing appearance. The core has a D-shaped yoke
with a 45° mitre joint. The core and tank are securely fixed and well protected during transportation.

We use a winding layout method that is supported by 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 processes, etc.

To meet the client’s needs, we can provide products of other voltage ratios, vector groups, and rated capacities, as listed in the tables below.
