Gas Insulated Switchgear Market Size, Share Global Report, 2026

Market TrendsMarket DriversMarket RestraintSegmentationRegional AnalysisKey Industry PlayersKey Industry DevelopmentsReport CoverageRequest a Free sampleto learn more about this report. Increasing Energy Demand Fuel Market Growth The growing population and growing rate of urbanization are likely to increase the demand for energy across the globe. According to the United Nations report in 2018, about 55% of the world’s population lives in urban areas, which is projected to increase to 68% by 2050. The extensive population shifting to cities is increasing the demand for electricity. Moreover, enormous construction activities to build commercial spaces, business parks, and housing societies are set to spike power demand. Hence, the space constraint in urban localities and growing energy demand is projected to further propel the gas insulated switchgear market growth during the forecast period.Get price

5 Technologies to Boost Efficiency in the TD System

HVDC – High-Voltage Alternating CurrentFacts (Flexible AC Transmission Systems) DevicesGas-Insulated SubstationsSuperconductors / Hts CablesWide Area Monitoring SystemsMost of the transmission lines that make up the North American transmission grid are high-voltage alternating current (HVAC) lines. Direct current (DC) transmission offers great advantages over AC, however: 1. 25%lower line losses, 2. Two to five timesthe capacity of an AC line at similar voltage, 3. Ability to precisely controlthe flow of power. Historically, the relatively high cost of HVDC terminal stations relegated the technology to being used only in long-haul applications like the Pacific DC Intertie, which connects the vast hydro power resources of the Columbia River with the population centers of Southern California. With the advent of a new type of HVDC, invented by ABB and dubbed HVDC Light, the benefits of DC transmission are now being realized on much shorter distances. The Cross-Sound Cable connecting Long Island and Connecticut is one example of this technology. Go back to Topics ↑Get price
