EGBN-12kV environmentally friendly gas insulated and metal-enclosed ring network cabinet uses micro-positive pressure dry air (or nitrogen) as the main insulating medium, and uses vacuum switches for opening and closing. The functional units are connected through fully insulated solid busbars. It is suitable for distribution system with three-phase AC 50Hz and rated voltage of 12kV. It is especially suitable for secondary distribution stations, switching stations, public buildings, residential areas, railways and airports. It can be used as the preferred equipment in harsh environments with high humidity, high pollution and high altitude.
Features
• Green and environmentally friendly: Dry air (or nitrogen) is used as the main insulating medium, without SF6, toxic or greenhouse gas emissions.
• Compact structure: The switchgear has a compact structure, which can greatly save the limited space. It also has excellent electrical insulation performance. The main busbar and outlet copper rod inside the gas box use bare conductors to reduce the application of polymer insulation materials.
• Safe and reliable: Mature vacuum switch technology, stable and reliable breaking performance and long service life.
• Environmental adaptability: All primary high-voltage components are sealed without being affected by the external environment and it truly meets the requirements of corrosion resistance, moisture resistance and low temperature resistance under special conditions.
• Intelligent configuration: The product conforms to the standard design of state grid, with flexible product combination and convenient installation.
