Power Transformer

Huawan power transformers are engineered for efficient energy transmission and distribution across high-voltage grids (66kV-765kV). They reliably step up/down voltages with >99% efficiency, minimizing energy loss. Featuring robust oil-immersed or dry-type designs, they serve utility substations, industrial plants, and renewable energy integration with 30+ year lifespans.
