High Voltage Industrial Switchgear Market Analysis

Current (AC, DC)

AC segment is projected to account for around 89.3% high voltage industrial switchgear market share by 2037 owing to its widespread use in power transmission and distribution systems. AC switchgear is preferred for its efficiency in transmitting electricity over long distances, as it allows voltage levels to be easily adjusted with transformers, minimizing energy loss. Additionally, the existing infrastructure globally is heavily built around AC systems, making upgrades and maintenance more feasible. Hence, the segment is projected to witness a significant rise during the forecast period.

In March 2022, State Grid Corporation of China launched two major ultra-high voltage alternative current (AC) power line construction projects, namely, Fuzhou-Xiamen and Zhumadian-Wuhan 1000kV UHV AC projects. Moreover, the demand for renewable energy integration, where AC transmission is commonly used, is witnessing a considerable rise. This further reinforces the dominance of AC in this segment, driving continuous investments in AC technologies in the high voltage industrial switchgear market.

Insulation (Air, Gas, Oil, Vacuum)

Based on insulation, the vacuum segment is projected to register considerable growth during the forecast period owing to its minimal maintenance requirements and superior performance in arc quenching. These switchgear are highly efficient at interrupting electric arcs, making them ideal for applications that require frequent switching and high reliability. In addition to these, vacuums also offer advantages such as compact design, longer lifespan, and environmental safety.

Unlike other insulation types which commonly use greenhouse gases such as SF6, vacuums do not require the usage of these gases. Vacuum insulations rather eliminated the need for SF6 while still offering high insulation strength and safety. The increasing focus on eco-friendly solutions and the need for reliable power distribution in industrial and utility sectors are driving the growth of vacuum insulation in the high voltage industrial switchgear market segment.
