The GSR6-12/24/40.5 series environmentally friendly gas-insulated metal-enclosed switchgear (C-GIS) is independently developed by our company. It is an eco-friendly gas-insulated metal-enclosed switchgear using dry air (Air) or nitrogen as the insulating medium. In terms of technical level, the product integrates vacuum circuit-breaking technology, APG solid-sealed technology, gas insulation technology, and interface insulation technology, representing a domestic medium-voltage complete switchgear solution. The product has passed type tests and new product technology identification inspections conducted by national authoritative testing institutions. It can be widely used in various crucial power distribution systems of the national economy, such as transmission and substation networks, urban power supply networks, large industrial and mining enterprises, petrochemical industries, metallurgy, and urban rail transit.
The product features a modular design and can be configured acco
Using internationally mature concepts, with world-class production and testing methods, laser welding, laser cutting, helium leak detection, and other equipment;
The product's components are designed with a fully sealed structure, completely enclosed in a stainless steel welded sealed air chamber, filled with pressurized dry air or nitrogen (N2) as an insulating medium. With a protection rating of IP67, it fully prevents the switchgear from being affected by external environmental conditions and can operate reliably in harsh environments such as basements, plateaus, permafrost areas, coastal regions, and humid locations, achieving maintenance-free operation.
The product can be operated manually or electrically. The operating mechanism is mature and reliable, and it is equipped with comprehensive mechanical and electrical interlocks, effectively preventing personal injury and equipment damage that may result from misuse.
The product design is compact, significantly reducing the volume compared to traditional air-insulated switchgear, decreasing the footprint by 30%-70%, improving space utilization, and effectively lowering overall project costs.
Based on microprocessor protection and system technology, it integrates protection, control, metering, monitoring, and communication functions, meeting the requirements of distribution network automation and digitization, and can achieve fully unattended operation.
