Our 220kV power transformer is core equipment for regional high-voltage power grid transmission and transformation, mainly used to convert voltage between 220kV and 110kV/35kV for large power grid hub stations, thermal power plants, hydropower stations and new energy base boosting stations.
Constructed from high-grade oriented silicon steel core and oxygen-free copper windings, the transformer features low no-load loss, small partial discharge and outstanding heat dissipation design. Optimized oil circulation cooling structure guarantees stable long-term running under full load and fluctuating ambient temperature. Strict full-process factory inspection and routine type tests are completed before delivery to comply with IEC & GB standards.
Equipped with reliable protection accessories including on-load tap changer, pressure relief valve, gas relay and temperature monitoring device, it effectively safeguards equipment against overload and abnormal faults. With strong adaptability, it works reliably in high altitude, severe cold and high-temperature areas.
Widely deployed in national backbone power grids, large industrial power stations, wind & solar centralized power bases and cross-regional power transmission projects.
