Gas Circuit Breaker Market: Global Industry Size, Share, Growth, Trends, Analysis and Forecast 2019
Gas circuit breakers are devices that interrupt the flow of electric current in case of a fault or overload. They are widely used in power transmission and distribution systems, as well as in power generation and renewable energy applications. Gas circuit breakers use pressurized gas, such as sulfur hexafluoride (SF6), as an insulating and arc-quenching medium.
The global gas circuit breaker market was valued at USD 621.2 million in 2021 and is expected to grow at a compound annual growth rate (CAGR) of 3.9% from 2021 to 2031, according to a report by Future Market Insights (FMI)[^1^]. The report covers the market by voltage rating, configuration, technology, end use and region.
Market Drivers and Restraints
The major factors driving the growth of the gas circuit breaker market are:
Increasing investments in power generation, especially from renewable energy sources. According to the International Energy Agency (IEA), the global investment in renewables generation was USD 281 billion in 2020[^2^]. Renewable sources such as solar and wind require dedicated protection systems, which boost the demand for gas circuit breakers.
Growing focus on secured power distribution and energy efficiency. Gas circuit breakers offer advantages such as high reliability, low maintenance, compact size and environmental friendliness over other types of circuit breakers.
Rising demand for reliable and safe electrical systems in residential, commercial and industrial sectors. Gas circuit breakers provide protection against short circuits, overloads and faults that can cause damage to equipment and personnel.
The major factors restraining the growth of the gas circuit breaker market are:
Stringent environmental and safety regulations for SF6 circuit breakers. SF6 is one of the most potent greenhouse gases (GHGs) with a global warming potential (GWP) of 23,000[^3^]. It is listed as an extremely harmful GHG by the Intergovernmental Panel on Climate Change (IPCC). The use of SF6 circuit breakers is regulated by various national and international authorities to limit its emissions and leakage.
High initial cost and installation complexity of gas circuit breakers. Gas circuit breakers require special handling and installation procedures due to their high pressure and toxicity. They also have a higher initial cost than other types of circuit breakers.
The global gas circuit breaker market is segmented based on voltage rating, configuration, technology, end use and region.
The voltage rating segment is divided into up to 72.5 kV, 72.5-145 kV, 145-252 kV, 252-550 kV, 550-800 kV and above 800 kV. The up to 72.5 kV segment accounted for the largest market share in 2020, owing to its wide application in distribution networks and renewable energy systems. The above 800 kV segment is expected to witness the highest growth rate during the forecast period, due to the increasing demand for ultra-high voltage transmission systems.
The configuration segment is divided into single interrupter, two interrupter and four interrupter. The single interrupter segment dominated the market in 2020, as it is suitable for low voltage applications. The four interrupter segment is projected to grow at the fastest rate during the forecast period, as it offers higher reliability and efficiency for high voltage applications.
The technology segment is divided into dead tank type and live tank type. The dead tank type segment held the largest market share in 2020, as it has a lower risk of gas leakage and explosion than the live tank type. The live tank type segment is expected to grow at a higher CAGR during the forecast period, as it has a lower weight and footprint than the dead tank type.
The end use segment is divided into transmission & distribution aa16f39245
