The RGF-40.5 series C-GIS is a new generation of intelligent high-voltage switchgear developed by our R&D personnel by combining the inherent characteristics of domestic and foreign power grids. This product has a primary circuit which is fully installed in the 304 stainless steel gas compartment filled with SF6 gas, and it also has such remarkable features as small installation volume, space-saving, high degree of integration, maintenance-free, simplified components and stable quality, so that it is widely applied in the transmission and distribution sites under various complicated conditions.
For the RGF-40.5 series switchgear, the usage amount of SF6 gas is reduced continuously in the manufacturing process, and no SF6 gas is used in the installation process.
The product is completely made of 100% reusable materials;
The self-powered relay and device are provided to avoid additional energy consumption;
Combination of individual unit schemes can be realized;
Common tank combination can be realized, and load switch, circuit breaker, PT and other schemes can be freely combined.
