Overview
Power Transformers
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
