The 35kV series power transformers feature advanced design with significant improvements in materials, structure, and processing.
The HV and LV clamping components are tightened using steel tension straps or upper and side beams to form a rigid frame structure.
This enhances core clamping force and resistance to transport impacts. The series offers high short-circuit withstand capability,
aesthetic appearance, reliable operation, low loss, and low noise, meeting the advanced standards of similar international products.
Our SZ13-20000/35 prototype successfully passed the sudden short-circuit test conducted by the National Transformer Quality
Supervision and Inspection Center. The HV and LV coils utilize longitudinal oil ducts for heat dissipation, significantly reducing the
temperature gradient between copper and oil, as well as the hot-spot temperature rise within the windings.
