The 330kV 63MVA oil-immersed power transformer serves as a critical component in high-voltage transmission and transformation infrastructure, optimized for ultra-high voltage power grid integration. This three-phase transformer meets the power evacuation requirements of large-scale power plant generators and the voltage conversion demands of regional power grid junctions, undertaking essential roles in large-capacity electricity transmission, transformation, and power distribution.

Guanggao Transformer is a professional manufacturer with nearly 25 years of transformer export experience. We produce single-phase, three-phase, dry-type, distribution, and high-voltage transformers (110 kV and above) that meet IEEE/ANSI/UL/CSA and IEC standards.
