Features
In response to the climate requirements set by the country and the implementation of the United Nations Framework Convention on Climate Change of 2005 and the Paris Climate Agreement of 2016, the world is working towards achieving peak control of greenhouse gas emissions as soon as possible. The goal is to limit the global temperature rise to within 2°C by 2025. To meet these goals, high voltage gas insulated switchgear (HV GIS switchgear), core GIS switchgear for power grids, and critical industrial switchgear represented by the HB-12 series must adopt environmentally friendly gas insulation media with a much lower Global Warming Potential (GWP) value.
The HB-12 series Gas Insulated Switchgear (GIS) uses a new, green, and environmentally friendly gas made from compressed air as the insulating medium. This eliminates greenhouse effect risks while providing stronger insulation performance. The gas is non-toxic and harmless, protecting equipment maintenance personnel from safety hazards caused by potential leaks. As a premium HV GIS switchgear and high-reliability industrial switchgear solution, the HB-12 series has become the ideal choice for building low-carbon, sustainable power distribution systems.
