High reliability 110kV oil immersed railway traction transformer

As the “heart” of the electrified railway traction power supply system, the performance of transformers directly determines the safety and efficiency of the entire railway network. Our carefully crafted 110kV oil immersed railway traction transformer adheres to top-notch engineering design standards and rigorous quality control system, optimized to cope with harsh railway loads, and is the trusted choice for global heavy-duty transportation and high-speed railway networks.

Authoritative design and excellent reliability

This product is designed and manufactured strictly in accordance with international and national standards such as IEC, IEEE, GB, osv. Its core adopts classic oil immersed technology, which has undergone decades of engineering verification and is recognized as one of the most mature and reliable solutions in the power industry. The oil immersed design not only provides excellent insulation and heat dissipation performance, but also endows the transformer with strong overload capacity and long service life, ensuring uninterrupted and stable power output under frequent start stop and severe load fluctuations in railway conditions.

Professional performance designed for railway traction

Sturdy winding structure: The winding is made of high-strength electromagnetic wire and advanced technology, and has passed strict dynamic and thermal stability tests. It has extraordinary short-circuit resistance and can effectively resist the impact of the power grid.

Efficient cooling system: Optimized oil circuit and heat sink (or heat pipe) design ensures excellent thermal management efficiency, effectively controls temperature rise, and ensures continuous full capacity operation of transformers in high temperature and high humidity environments.

Excellent electrical performance: High quality high magnetic conductivity silicon steel sheets are selected, combined with precise magnetic circuit design, to reduce no-load and load losses to extremely low levels, with outstanding energy efficiency performance throughout the entire life cycle, in line with the energy-saving requirements of modern green railways.

Comprehensive safety protection: equipped with complete pressure relief valves, gas relays, temperature controllers and other safety protection devices, and can be optionally equipped with intelligent online monitoring systems to achieve real-time diagnosis and warning of transformer health status, empowering predictive maintenance.
