110 kV-Class Power Transformers
Our company’s 110 kV oil-immersed power transformers feature a core without suspension and a leak-proof design. They are characterized by low losses, low noise, low temperature rise, and minimal partial discharge, and are fully compliant with IEC standards.
They are widely used in power plants, power grid substations, wind and solar power plants, as well as mining and petrochemical industrial parks. We can provide customized insulation classes, tap changer types, and performance ratings for both domestic and international projects.
All products certified to ISO9001(Quality), ISO14001(Environment), ISO45001(Safety). Independent HV lab for full‑type testing.
