HV Gas Insulated Switchgear Market Trends

The market for HV gas insulated switchgear (VIS) is showing new developments and growth trends due to the global shift towards sustainable and efficient power distribution systems. One of the leading trends is the growing use of greener technologies. It is expected that the HV gas insulated switchgear will start dominating the gas insulated switchgear market, as it does away with the use of sulfur hexafluoride gas insulated transformers, SVSF6, which are high emitters of greenhouse gas. Stricter emission control measures put in place by governments and environmental agencies are pushing towards the use of gas technology HV’s environmental impacts are significantly less.
 

Furthermore, the growth trend of urbanization and limited availability of land is acting as a catalyst to the demand for small sized and high reliability switchgear systems. HV Gas insulated switchgear is expected to be more compact and efficient, especially in urban substations, industrial plants, and high-density residential buildings. These regions, which are currently undergoing infrastructure expansion, also prefer minimal space without performance issues.
