- Product Overview
GSR8-12 Air Gas-insulated Metal-enclosed Switchgear is a new type of medium-voltage switchgear independently developed by our company. This product is mainly used in 10kV 50Hz three-phase AC power supply systems, and is also suitable for power plants, residential areas, industrial and mining enterprises, substations and other important power supply places to achieve uninterrupted and reliable power supply. The product adopts a modular design and can be arranged arbitrarily according to different design schemes to achieve a perfect combination of common box type and expansion unit, meeting the needs of various secondary transmission and distribution substations for flexible use of compact switch cabinets.
GSR8 series switchgear is a completely sealed system. All primary live parts and switchgear are enclosed in a stainless-steel gas tank and are not affected by the environment. It has the characteristics of reliable operation, safety, compact structure design, small footprint, and lifelong maintenance-free.
- Product Features
- Safe and reliable
- The high-voltage components and main switch are completely sealed in a stainless-steel gas tank with IP67. The interior of the gas tank is not affected by the external environment and has short-term anti-flood and anti-condensation functions.
- The equipment has reliable pressure release devices and pressure relief channels to ensure personal safety when a fault occurs; it has a complete mechanical interlocking device to prevent misoperation to the greatest extent.
- Green and environmentally friendly
- Air insulation, green and environmentally friendly, with a wider range of applications
- Insulating performance is not affected by altitude.
- Can be installed in humid, sandy and dusty areas, salt spray, mines and other areas without taking special precautions.
- Modularity, flexible combination and extension
- Having different module design: C module, V module, PT module, and Metering module, etc., they can combine freely to form a Ring Main Unit.
- Modules are connected by extension busbar to achieve full modular configuration.
