Product Description

New Electric Power three winding oil immersed power transformer is designed for medium and high voltage power transmission systems, supporting 66kV/33kV/11kV voltage conversion for substations, mining plants, industrial facilities and grid electrification projects. It provides stable power distribution, high efficiency and long service life in harsh environments.


High Voltage Three Winding Design for Flexible Power Distribution

Adopts three winding structure to realize multiple voltage level conversion within one transformer, reducing equipment investment and improving substation efficiency. Suitable for 66kV, 33kV and 11kV power networks, mining power supply and regional grid expansion projects.


Durable Oil Immersed Cooling System for Harsh Environments

Uses high-quality mineral insulating oil and ONAN/ONAF cooling technology to provide excellent heat dissipation and reliable continuous operation. The sealed tank structure protects internal components from moisture, dust and extreme outdoor conditions in Africa markets.


High Efficiency Core & Copper Windings for Energy Saving Operation

Equipped with premium grain oriented silicon steel core and oxygen-free copper windings to reduce no-load loss, load loss and operating costs. Optimized electromagnetic design ensures stable voltage regulation and efficient power transmission.


Built for Substations, Mining & Infrastructure Power Projects

Designed according to IEC 60076 standards, this transformer provides reliable performance for utility grids, mining plants, renewable energy connection, industrial parks and large-scale electrification projects.
