HBG-12 Environmental Protection Gas Closed Loop Switchgear - China Suppliers & Factory for Eco-Friendly Power Distribution
Model and meaning
Product features
comprehensive functions, combined product
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 an 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 the 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 a three-position switch (closing + breaking + grounding) and a vacuum arc-extinguishing chamber, which is a mature configuration and ideal for current power grid operation and maintenance.
Environment-friendly without pollution
HBG-12 Environmental Protection Gas Closed Ring Main Unit Switchgear adopts level-zero dry air (purchased) or 99.99% pure N2 in accordance with GB/T 8979-2008. Any gas leaked will not impact external environments, and there is no need to recycle.
