HBG-12 Environmental Protection Gas Closed Loop Network Switchgear - Eco-Friendly Solution by China Suppliers & Factory

The HBG-12 Environmental Protection Gas Closed Ring Main Unit Switchgear represents a cutting-edge solution in the field of green energy. As a leading product manufactured by our factory in China, this innovative metal-enclosed switchgear utilizes environmentally friendly gases such as dry air or nitrogen for insulation, ensuring minimal greenhouse gas emissions. With a material recycling rate exceeding 90% at the end of its lifecycle, it is designed with sustainability in mind, featuring degradable materials and avoiding the use of epoxy resin in almost all insulating components except for the bushing.

Our switchgear includes advanced vacuum arc-extinguishing circuit breakers and load switches, allowing for exceptional adaptability in various environments. Its compact design occupies minimal space and eliminates the need for SF6 gas detection and protection systems. This results in a safe, reliable, and maintenance-free operation, aligning with the future trends in ring main unit development.

The HBG-12 is particularly suited for 12kV, three-phase AC 50Hz applications, functioning seamlessly within single-bus and single-bus sectionalized power distribution systems. It is ideal for use in urban residential areas, small secondary substations, switchgear houses, cable distribution boxes, box-type substations, and various industrial and commercial settings including shopping malls, airports, subways, wind power generation sites, hospitals, stadiums, railways, and tunnels. As a trusted supplier of high-quality switchgear solutions in China, our commitment to environmental protection and innovative technology sets us apart in the industry.

    The inflatable shell of the switchgear is made of high-quality 2.5mm thick stainless steel plate by laser welding to make the gas tank sealed reliably with high mechanical strength, highly resistant to corrosion, and the protection grade of the inflatable shell is IP67. The gas tank is equipped with explosion-proof diaphragm to effectively prevent any damage to people and equipment due to high gas pressure. All conductive parts are enclosed in the gas tank to prevent influence of external environments and make it run reliably, free from maintenance (or with little maintenance). At the same time, it is compact as required. The main circuit is equipped with three-position switch (closing + breaking + grounding) and vacuum arc-extinguishing chamber, which is a mature configuration and ideal for current power grid operation and maintenance.
