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

Static Electricity Discharge and Fire Prevention - Chemical

Static RiskIsolated ConductorsStatic Discharge SourcesStatic Discharge PreventionStatic electricity discharges are possible almost continuously in the chemical process industries (CPI), because static electricity is generated whenever surfaces come into contact and then separate. In most cases, the charging currents generated over time in industrial processes are small — typically no greater than 1 × 10–4Amps. However, in hazardous areas, even small charges can be a problem when the allowed to accumulate on objects that are not at ground (earth) potential. If no ground is present, voltages in excess of 30 kV can develop. Depending on the capacitance of the object, this may result in significant levels of energy being available for discharge. If the energy equals or exceeds the minimum ignition energy (MIE) of the surrounding flammable atmosphere, the potential for an explosion and fire exist. Many commonly used solvents and other flammable chemicals have MIEs that are relatively low — on the order of 1 mJ or less (Table 1).Get price
