Hebei Heiniu leverages its dedicated FRP (Fiber Reinforced Plastic) insulation materials workshop to produce advanced composite material insulator products that represent the modern standard for overhead line insulation. Our composite material insulator, also known as a polymer or silicone rubber insulator, offers superior performance compared to traditional materials due to its high strength-to-weight ratio, excellent hydrophobic properties, and outstanding resistance to vandalism and pollution flashover. The core of our composite material insulator is made from epoxy resin-impregnated fiberglass rods, fabricated in-house for quality control, and covered with weather sheds of high-performance silicone rubber formulated to resist UV degradation and tracking. Every composite material insulator undergoes comprehensive testing in our testing center for electrical, mechanical, and aging characteristics, ensuring compliance with international standards. We provide customized composite material insulator designs for suspension, tension, and post applications, supported by our technology development center and customer-oriented service, making it an ideal choice for enhancing grid resilience and reducing maintenance.
