Epoxy resin is favored for its superior mechanical strength and electrical insulation properties, making it ideal for use in high-voltage environments. Glass-reinforced polyester, on the other hand, offers excellent flame retardant properties and dimensional stability, which makes it suitable for both indoor and outdoor applications, including harsh environments with significant temperature variations. Thermoplastics are often used for low-voltage applications due to their lightweight nature and cost-effectiveness while still providing sufficient electrical insulation.
In terms of applications, switchgear insulating materials are used in various components such as bushings, insulating barriers, support insulators, and busbar supports. These materials play a critical role in enhancing the durability and operational safety of switchgear assemblies by isolating conductive parts and ensuring the smooth operation of electrical distribution systems. By maintaining the integrity of the electrical circuits, insulating materials help to minimize maintenance costs and downtime, ensuring a reliable power supply to industrial, commercial, and residential sectors.
