  • 【 Taporel 】 Major Breakthroughback Of Large Diameter Rod Used For UHV Composite Post Insualtor

    Why we use grinding FRP rod

    The insulator is usually made of silicone rubber material. The surface of the core rod purchased is relatively smooth. In order to ensure the durability of the interface between the insulator core rod and the housing during the manufacture of the insulator, the surface of the core rod needs to be sanded. Roughen the surface film of the core rod to increase the surface reactivity and facilitate bonding with the adhesive.
