Power Transformer is an electrical device used to transfer power from one circuit to another without changing the frequency. It is an important element in the distribution of power systems, providing power support for large industrial sites. The maximum rated capacity of the QXG power transformer is 50000mva, and the high voltage access terminal voltage is between 35kv-500kv.

QXG’s high-voltage transformer(above 35KV) are designed, built, and tested in accordance with the highest industry standards including NEMA, ANSI, DOE, and IEEE as applicable.
It’s a device that converts high-voltage AC power to low-voltage AC power or vice versa. High-voltage transformers are mainly used for testing electrical equipment and components under high voltage conditions in laboratories or factories. They can also be used for power transmission and distribution.
Product Scope: 200 kVA – 240,000 kVA base, Up to 220kV
