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.

The rise of AI is profoundly reshaping the transformer industry from four aspects: the emergence of demand, product upgrades, intelligent manufacturing and operation, and the structuring of the industry chain. It represents both a huge growth opportunity and a technological and business model elimination competition.

The transformer bushing is a crucial component that allows the high-voltage lines to pass through the transformer oil tank while providing insulation and fixation.

Choosing the appropriate transformer for your power distribution needs requires that you differentiate between oil-filled transformers and dry-type transformers. The two transform the electricity throughout your facility. However, there are important differences in their construction, application, performance, and the maintenance required. This article will outline the differences, the pros and cons of each type of transformer, and provide you with information to make an educated decision on your next transformer purchase.
