Our composite polymer pin insulators are designed for overhead distribution lines ranging from 12kV to 36kV. Utilizing advanced injection molding technology, the silicone rubber housing is chemically bonded to the fiberglass core, ensuring zero moisture ingress and preventing brittle fractures. Ideal for coastal areas, industrial zones, and high-altitude deployments.
