Product classification
ESRAirplus|CGIS) Environmental Gas Insulated Metal Enclosed Switchgear
ESR Airplus environmentally friendly gas-insulated metal-enclosed switchgear is used in 10kV distribution systems with a rated frequency of 50Hz. The main switch circuit is enclosed in a fully insulated and fully sealed stainless steel gas chamber, which uses dry air (D-air) or nitrogen (N₂) as the insulating medium, achieving green environmental protection without SF6 gas. Throughout the entire operational life cycle of the equipment, there is no need for gas recovery treatment, resulting in no pollution and safe, reliable operation. This product is a three-phase AC single bus and bus section indoor complete device, mainly used in distribution systems of power plants, substations, high-rise buildings, and industrial enterprises to control, protect, and monitor the power supply system and loads.

Product Features:
▪ Green and environmentally friendly: Dry air or nitrogen as the insulating medium in the gas chamber, no SF6 gas, no toxic gas, and no greenhouse gas emissions;
▪ High insulation, anti-condensation, and anti-pollution: The conductive circuit is fully insulated and fully sealed, and the equipment operation is not affected by the environment, suitable for operation in humid and polluted environments;
▪ High altitude: The main circuit is fully enclosed, and the product operation is not affected by altitude, suitable for altitudes of 4000 meters;
▪ "Zero" gauge pressure normal operation: The main circuit electric field in the gas chamber is designed to be uniform, with good insulation performance. The gas chamber can meet the requirements of 10KV power frequency and lightning impulse tests in humid environments without being sealed, fully achieving zero gauge pressure operation;
▪ Miniaturization: Compact design, saving space;
▪ Slight positive pressure in the gas chamber: The gas chamber is designed with slight positive pressure to prevent humid air from entering the gas chamber;
▪ Flexible expansion: The switch cabinet can be expanded left and right, making it convenient, beautiful, and practical. The product is designed for standardization, allowing for flexible and convenient combinations of different schemes;
▪ Complete mechanical and electrical interlocks to effectively avoid misoperation;
▪ High-strength thermoplastic recyclable materials as insulating media, achieving environmental protection performance;
▪ The primary circuit is enclosed in a sealed gas chamber, and the shell can be safely touched;
▪ Large cable installation space, with horizontal arrangement of cable plugs, making cable installation convenient.
