advantages of traction transformer

Cooling and Insulation:

1. Oil Immersion:The transformer windings and core are immersed in mineral oil, which serves both as a coolant and an insulator. This enhances the transformer's ability to handle high power loads and maintain temperature stability.
2. Radiators/Heat Exchangers:These are often attached to facilitate efficient heat dissipation from the oil, ensuring the transformer operates within safe temperature limits.

High Efficiency:

1. Reduced Losses:Oil-immersed transformers generally have lower losses compared to dry-type transformers, making them more efficient in energy transmission.
2. Improved Performance:The oil provides excellent dielectric strength, reducing the risk of short circuits and enhancing overall performance.

Durability and Reliability:

1. Robust Design:These transformers are designed to withstand harsh operating conditions, including mechanical shocks and vibrations typical in railway applications.
2. Longevity:Properly maintained oil-immersed transformers can have a long service life, often exceeding 25 years.

Customization:

1. Tailored Solutions: our factory can provide customized transformers to meet specific voltage, power, and operational requirements of different railway networks.

   Applications in Railways

   High-Speed Trains:

   Oil-immersed transformers are crucial for supplying stable and reliable power to high-speed trains, which demand high power and efficiency.

   Urban Rail Transit:

   They are also used in metro systems and light rail transit, providing consistent power supply in densely populated urban areas.

   Freight Trains:

   Heavy-duty freight trains benefit from the high efficiency and reliability of oil-immersed transformers, ensuring smooth operations over long distances.
