Gas-Insulated Switchgear (GIS) for Primary Distribution

Class 6047 / Refer to Brochure 0600BR1201

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.

CBGS-0 Gas-Insulated Switchgear (UL Listed)

Listed Metal-Enclosed
Interrupter Switchgear

Easy innovative and economical up to 38kV

CBGS-0 Medium Voltage (MV) switchgear is compact and easy to install and operate. Due to the insulating gas as well as the solidly insulated busbar and cable connections the medium voltage circuit is protected from environmental influences reducing the risk of arc flash events.

Each section consists of a sealed-for-life SF6 tank which contains the fixed SF range circuit breaker and disconnect switch. 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.

Front accessible and ideal for a variety of applications from transformer substations to primary power distribution in markets ranging from mining and metals renewable installations container substations and heavy industry where space is at a premium.
