SZ-33/11kV Oil-Immersed Power Transformer

SZ-33/11kV Oil-Immersed Power Transformer

2026-06-27

The SZ series transformers feature an on-load tap-changer (OLTC) design, enabling stable output voltage adjustment without power interruption. The transformer capacity typically ranges from 1,000kVA to 31500kVA (customizable for larger capacities), making them suitable for adapting to grid voltage fluctuations. Manufactured with high-quality cold-rolled grain-oriented silicon steel cores and high-conductivity copper windings, combined with high-grade insulating oil, these transformers deliver high load capacity, low losses, low noise, and strong short-circuit withstand capability. With excellent electrical performance, heat dissipation, and operational reliability, the SZ series is particularly well-suited for large-scale power applications that demand high supply continuity and power quality.
