Government initiatives that support rural electrification, grid modernisation, and renewable energy integration serve as key drivers for market expansion. Smart grid technology development and energy-saving regulations drive up the need for AIS. The industry will expand further because countries focus on building sustainable energy systems.

Installation Insights

The indoor segment led the air-insulated switchgear market with the largest revenue share of 58.6% in 2024. The segment maintains its position because it serves commercial and industrial facilities and residential areas, which need to follow safety rules and manage limited space. The small size of indoor AIS systems makes them easy to install while they protect against environmental factors such as moisture and dust, and extreme temperature conditions. This makes them the preferred choice. The system provides stable and efficient power distribution, which makes it essential for data centres, factories, hospitals and office buildings. The segment experiences growth because electrical solutions require smart and compact designs and because urban infrastructure construction continues to expand. Digital and modular indoor switchgear systems have become more advanced, which enables better system monitoring and operational performance.

The outdoor segment of the air-insulated switchgear market is expected to grow at a significant CAGR over the forecasted period because of expanding power transmission and distribution infrastructure investments that focus on rural and isolated areas. The high voltage capability of outdoor AIS systems, along with their ability to operate reliably in harsh environmental conditions, makes them ideal for use in substations, renewable energy facilities, and utility-scale installations. The choice of large-scale grid expansion projects depends on this technology because it provides a durable solution at a lower cost than gas-insulated alternatives during installation. Outdoor switchgear experiences high demand because national grids keep adding solar and wind renewable energy sources. The market will grow because of government programs that support grid modernisation and rural electrification efforts.

Application Insights

The transmission & utilities segment led the air insulated switchgear market with the largest revenue share of 47.9% in 2024. The need for reliable power distribution systems in growing urban and rural areas has become the primary reason behind this market dominance. The combination of low cost, simple maintenance, and proven effectiveness in medium to high voltage systems makes AIS the preferred choice for utilities and grid operators. The market receives support from developing nations through their expanding power usage, their dedication to grid modernisation, and their implementation of major infrastructure projects. The market experiences growth because of the need to replace deteriorating infrastructure and the adoption of renewable energy systems into national power grids. The transmission networks have become the industry leader through substantial financial support from utilities and government entities.

The industrial segment of the air-insulated switchgear market will experience a significant CAGR throughout the forecast period because industrial infrastructure development and energy consumption growth in manufacturing, mining, oil and gas, and chemical sectors. The manufacturing sector requires AIS power distribution systems which provide cost-effective and durable solutions with minimal maintenance needs to maintain ongoing operations. The need for advanced electrical infrastructure, including modern switchgear systems, increases because of automation and smart manufacturing technology adoption. Organisations are upgrading their outdated switchgear systems because safety regulations have become more stringent and energy efficiency standards have risen. Businesses want to run their operations in an environmentally responsible way.
