High Voltage Commercial Switchgear Market Analysis

Insulation (Air, Gas, Vacuum, Others)

The air segment based on insulation is poised to dominate the high voltage commercial switchgear market with a 44.4% revenue share by the end of 2037. The segment’s dominant market share is attributed to the cost-effectiveness of Air Insulated Switchgear (AIS) and ease of maintenance. The use of air as a primary insulation medium makes AIS an eco-friendly alternative to the use of SF6. This positions the segment to tap into the growing push for sustainable energy trends. For instance, in December 2023, Linxon announced that it was awarded another turnkey substation contract by Svenska Kraftnät (SvK) to deliver new 400 kV air insulated switchgear (AIS) substation.

The gas insulated switchgear (GIS) segment is projected to increase its revenue share by the end of the forecast period. The segment is widely used in many emerging economies owing to its reliability and ability to handle high loads in limited space. SF6 is the primary insulation medium of GIS and offers superior performance in electric insulation. Additionally, new innovations to replace SF6 with green gas is poised to boost demands for GIS. For instance, in August 2024, GE Vernova announced that it will manufacture, deliver, and commission the world’s first SF free gas insulated substation (GIS) in France.

Current (AC, DC)

The alternating current (AC) segment in the high voltage commercial switchgear market is projected to register a rapid growth during the forecast period owing to the segment cementing itself as a standard choice to manage high voltage power flow. The segment benefits from modernization efforts for power grids in emerging economies. Additionally, growing investments in rural electrification projects boosts the market’s growth as demands for high voltage AC switchgear increases. For instance, in September 2024, Honeywell announced its BESS technologies are being integrated into the microgrid of the remote Kavaratti islands of Lakshadweep.
