Gas-Insulated, 12 kV, SF6-Free Ring Main Unit (RMU) - HB-12 Series

Gas-Insulated, 12 kV, SF6-Free Ring Main Unit (RMU) - HB-12 Series

LMHB-12 Series Energy-saving And Environmentally Friendly Fully Insulated Ring Network Switchgear.
In response to the climate requirements issued by the country and the implementation of the United Nations Framework Convention on Climate Change of 2005 and the Paris Climate Agreement in 2016, the world will achieve the peak control of greenhouse gas emissions as soon as possible, and the global temperature rise in 2025 will be controlled within 2°C. Therefore, for inflatable cabinets, we need to reconsider environment-friendly gas insulation media with a smaller GWP value.

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.
