Composite insulators are advanced electrical insulation products made of fiberglass reinforced epoxy (FRP) rods, silicone rubber sheds, and metal end fittings. Compared with traditional porcelain insulators, composite insulators are lightweight, resistant to pollution, anti-aging, and provide excellent mechanical strength, making them widely used in power transmission and distribution systems.

Composite insulators are widely applied in:
High-voltage transmission and distribution lines (suspension, strain, and post types);
Urban distribution networks and railway electrification projects;
Substation equipment and switchgear insulation components;
Coastal, desert, and high-pollution regions requiring enhanced insulation performance.
Manufacturers provide customized solutions based on specific project requirements, including voltage ratings, creepage distances, shed profiles, and end fittings. OEM/ODM services are available to support brand customization and compliance with different international standards.
