New bushing materials, such as RIP and RIS, also help extend transformer life and reduce maintenance needs, reinforcing the importance of transformers in modern energy infrastructure.

• The polymers segment holds the second-largest share of the electrical bushings market, thanks to their superior technical performance, durability, and cost-effectiveness. Polymer-insulated bushings offer several advantages, including lightweight construction, high mechanical strength, and reduced complexity in transportation, installation, and maintenance. These bushings are more resistant to moisture, pollution, and harsh environmental conditions, making them ideal for use in coastal areas, regions with high pollution, and areas with extreme weather. Their long service life and low failure rates make them particularly well-suited for high-voltage transformers, circuit breakers, and switchgear systems. The growing adoption of renewable energy systems and smart grid technologies further boosts demand for polymer-insulated bushings due to their reliability and efficiency. Their anti-fragmentation properties also ensure greater safety in the event of failure compared to porcelain-based alternatives. Continued advancements in material technology are expected to strengthen the performance and dominance of polymer bushings in power transmission and distribution.

• The oil-impregnated paper (OIP) bushings segment is the largest in the electrical bushings market due to their high reliability, excellent dielectric properties, and long history of use in high-voltage applications. OIP bushings, which combine paper insulation with oil impregnation, offer superior insulation strength and reduce the likelihood of electrical breakdown, making them suitable for high-voltage and heavy-load conditions. They are widely used in critical applications such as power transformers, circuit breakers, and reactors across transmission and distribution networks. OIP bushings are preferred for their cost-effectiveness and long operational lifespan, despite the rise of alternative technologies like polymeric or RIP bushings. Their proven track record and ability to maintain stable performance in challenging environmental conditions, including high-temperature and high-pressure settings, ensure their continued adoption in utilities and industries. The growing demand for grid modernization, power generation projects, and the replacement of aging infrastructure, particularly in Asia Pacific and Europe, further strengthens the market position of OIP bushings.
