35kV Power Transformers: 

The 35kV series power transformers feature advanced design, with significant improvements in materials, structure, and manufacturing processes. The high and low voltage clamps utilize steel straps or upper and side beams for tension, forming a robust frame structure that enhances core clamping force and resistance to transportation impacts. They boast strong short-circuit withstand capability, an attractive appearance, reliable operation, low losses, and low noise, reaching advanced levels compared to similar international products. Our SZ13-20000/35 transformer prototype passed the sudden short-circuit test conducted by the National Transformer Testing Center on its first attempt. The longitudinal oil channels in the high and low voltage coils facilitate heat dissipation, significantly reducing the temperature difference between the copper oil and the hottest spot temperature rise within the coil.
