Our oil immersed power transformer is designed for 110kV–220kV medium and high voltage power transmission and distribution systems, delivering stable and efficient voltage conversion for substations, utility grids, and large industrial projects. With a wide capacity range from 500kVA to 10000kVA+, this power transformer is ideal for heavy-load and long-term operation.
This oil filled transformer adopts mineral oil immersion cooling technology, ensuring excellent heat dissipation and stable performance under continuous high-load conditions. Equipped with multi-protection systems (short circuit, overload, over temperature, gas protection), it guarantees safe operation and minimizes electrical risks in critical infrastructure.
Built with high-quality cold-rolled silicon steel core and oxygen-free copper windings, this oil immersed transformer achieves low no-load loss, low load loss, and high energy efficiency, outperforming industry standards. It is an ideal solution for projects requiring energy saving and long-term cost reduction.
The transformer features a fully sealed, corrosion-resistant tank with oil leakage prevention and explosion-proof design, suitable for outdoor installation. With protection up to IP rating standards, it ensures reliable operation in humid, high-temperature, and harsh environments.
This high voltage oil immersed transformer is widely used in:
Ideal for power transformer manufacturers, EPC contractors, and grid projects
