Product Description

Power Transformer

Power transformers are a core component of power transmission system. The substation transformer used for power transmission and transformation in a unit or substation, and is also the core part of the substation. Transformers are the core equipment of the traction power supply system of electric locomotives, and also the key equipment to ensure the safe and stable operation of the traction power supply system.
