Glass Insulated Electrical Bushing Market Outlook:
Glass Insulated Electrical Bushing Market size was valued at USD 1.63 billion in 2025 and is set to exceed USD 2.73 billion by 2035, expanding at over 5.3% CAGR during the forecast period i.e., between 2026-2035. In the year 2026, the industry size of glass insulated electrical bushing is estimated at USD 1.71 billion.
The glass insulated electrical bushing market has accelerated at a rapid pace attributable to the rising interest in efficient energy transmission systems. Glasses are preferably used as they provide superior insulation properties compared with other materials and also exhibit mechanical strength and resistance to environmental influences such as moisture or pollution.
Renewable energy projects are adding further to the increased demand for glass-insulated bushings, as wind and solar power are rising. Many countries are upgrading power infrastructure towards clean-energy-generation sources, making them ideal for power transformers, gas-insulated switchgear, and other high-voltage equipment. For instance, in February 2020, Indiana Michigan Power, an American Electric Power division, announced investing USD 77 million to modernize and construct new substations as part of its electric transmission network. The shift toward modernized and smart grids is enhancing the prospects for the glass insulated electrical bushing market.
