Gas Insulated Switchgear (GIS) Series
Gas Insulated Switchgear (GIS) is a compact, metal-enclosed electrical substation component that uses sulfur hexafluoride gas or eco-friendly alternative gases for electrical insulation. It integrates vital grid equipment—including circuit breakers, disconnectors, busbars, and current transformers—into a sealed, pressurized metallic housing. GIS technology is primarily deployed in high-voltage and medium-voltage power grids, urban substations, industrial plants, and offshore wind farms.
HBXGN2 12 Energy Saving Eco Friendly Gis Ring Main Unit
The HBXGN2-12-630/20 energy-saving and environmentally-friendly ring main unit – circuit breaker cabinet is an eco-friendly switchgear independently developed by our company based on the development trends of the power industry and our years of experience in distribution network field service and design & construction.
Metal fully enclosed gas-insulated ring main unit is an SF6 gas-insulated metal enclosed switchgear. This equipment can be composed of modules such as load switch units, load switch-fuse combination units, vacuum circuit breakerunits, and busbar inlet units.
AC metal-enclosed ring main unit (hereinafter referred to as the ring main unit) is a new high-voltageelectrical product that we have independently designed and successfully developed based on imported foreign technology and inaccordance with the requirements of domestic rural electrification and urban network transformation. All technical performanceindicators fully comply with IEC298 and GB3906 standards.
Solid insulated ring main unit is a fully insulated, fully sealed, maintenance-free solid insulated vacuum switchgear. All highvoltage ive parts are cast with epoxy resin materials with excellent insulation properties, integrating the vacuum arc extinguishing chamber, mainconductive crcuit, and insulating supports into a single unit Functionalunits are connected via a fully insulated solid busbar.
