PRODUCT OVERVIEW
The bell type tank and the corrugated shell increases the strength oftank with beautiful appearance.
The core is with D shape yoke with 45° miter joint.
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, ect.
To meet the client's needs, we can provide products of other volage ratios, vector group, and rated capacities, as listed in the table.
