• Product Overview

GSR6-72.5/1250-31.5kA Offshore Wind Power Gas Insulated Metal Enclosed Switchgear (C-GIS) is a new generation of high-voltage switchgear independently developed by our company to fill the domestic shortage and has leading technology level. It is suitable for power systems with voltage level of 72.5kV and three-phase AC 50Hz. The equipment is generally installed on the platform inside the wind turbine tower, mainly used for the connection between the step-up transformer and the wind turbine collection cable, and for switching, controlling and protecting the main electrical circuit of the wind turbine.

This product is a new generation of high-voltage complete combination electrical equipment that integrates vacuum arc extinguishing technology, solid-sealed pole technology, gas insulation technology and interface insulation technology. The equipment adopts intelligent control and protection units, has perfect control, protection and measurement functions, and can fully meet the needs of offshore wind power collection network systems.

• Product features

1. Security

• The high-voltage components are completely sealed and the insulation performance is not affected by the marine environment.

2. Reliability

• The main switch adopts vacuum arc extinguishing, which has strong breaking capacity and is safe and reliable. Micro-positive pressure gas insulation, and the components are strong in withstanding harsh environments.
• Block design, specially designed for the wind turbine tower environment, compact structure can more effectively use the space non-removable parts (air box > maximum width less than 1100mm, convenient for entering and exiting the tower door.

3. Economical

• Fully enclosed switch, long service life and not affected by the environment. Fewer maintenance requirements can save operating costs to the greatest extent. · Multi-circuit inlet and outlet lines to meet the connection of various collector cables.
