Railway traction transformer
Product Features:
The transformer that supplies power to railway traction line is called railway traction transformer. Our company uses the world's advanced transformer design technology and manufacturing process, and adopts the programmed design to analyze and quantitatively calculate the dielectric breakdown mechanism, electric field numerical analysis and insulation technology, wave process impact characteristics of winding and anti sudden short circuit strength, etc. In combination with our company's years of experience in manufacturing traction transformers, we have made a great breakthrough on the basis of traditional technology, thus further improving the reliability and advanced nature of the products. Products have low temperature rise, low loss, low noise, high efficiency, high anti-short circuit ability, strong overload capacity and other outstanding technical characteristics.
Advantage:
The body adopts a new type of insulation structure to improve the ability to withstand short-circuits;
Spiral coil with longitudinal oil passage has a better internal heat dissipation;
High efficiency, low loss, can save a lot of power and operating costs;
The surface of the corrugated oil tank is coated with three anti-paint after oil removal, rust removal, and phosphating.
It is suitable to use in metallurgy, petrochemical, and mining environments.
1, low no-load loss and low load loss;
2, low noise;
3, low voltage partial discharge;
4, high anti short-circuit capacity;
5, reliable performance, no oil leakage and no damages.
