GHA

Gas-insulated switchgear with gas-insulated busbar for heavy duty applications up to 38kV.

GHA is UL listed and offers high ratings for 38kV applications. This robust, gas-insulated switchgear has a unique busbar system incorporating busbar link or B-Link technology which eliminates the need for gas handling on-site. This allows end-users to take advantage of the benefits of complete gas-insulation with a more eco-friendly solution.

GHA
  • Features

    GHA is compact and modular switchgear incorporating the reliability of vacuum circuit breaker technology with gas-insulation. GHA is designed as functional modules, which are connected using the reliable and innovative B-link connectors. This compact and reliable equipment is suitable for a wide range of applications, performs in highly polluted environments, and is designed to be installed next to a wall.
