GHA Gas-Insulated Switchgear (UL Listed)

Listed Metal-Enclosed
Interrupter Switchgear

Easy, innovative, and economical up to 38kV

GHA Medium Voltage (MV) switchgear is an ideal solution for a variety of applications and requirements. GHA is well suited for public and industrial distribution networks, infrastructure projects, petrochemical oil and gas industries, and container substations to name a few. This compact and modular switchgear offers both flexibility and a long, low-maintenance service life.

Each section consists of sealed-for-life SF6 modules, which contain the fixed vacuum circuit breaker, disconnect switch, and innovative busbar system. By design, there is no gas handling throughout the service life of the equipment, from installation until recycling at the end of life of the switchgear. Utilize the cutting-edge B-link busbar to easily install, extend, or replace gear in the middle of a lineup, without handling SF6. Like the gas-filled modules, the B-link system does not require any maintenance.

Front accessible and ideal for a variety of applications, GHA represents the new generation of robust, extremely compact, and low maintenance MV switchgear.
