Overview of 110 kV Railway Traction Transformers
110 kV traction transformers are essential components in railway power supply systems. Used in AT (Automatic Transformer), BT (Booster Transformer), or direct power supply systems, they ensure stable, reliable energy for high-speed trains. These transformers often convert three-phase AC to two-phase balanced traction networks, supplying the necessary voltage and current to the catenary system.
Widely applied in multiple high-speed rail lines, these transformers are engineered for high reliability, low losses, and long-term stability, making them the backbone of modern railway electrification projects.
