11kV silicone rubber pin composite insulators are essential components for low and medium voltage power distribution systems, designed to provide reliable mechanical support and electrical insulation for overhead lines. Manufactured by HAIVO, these pin type composite insulators integrate high-quality silicone rubber housing, modified ECR fiberglass reinforced epoxy resin core rods, and precision-crimped end fittings into a single robust unit.
Our 11kV composite pin insulators are engineered to operate flawlessly in rated voltages up to 36kV, delivering superior performance compared to traditional porcelain and glass insulators. They feature a compact, lightweight design that simplifies transportation and installation, while their exceptional hydrophobicity and anti-pollution properties ensure long-term reliability in harsh environmental conditions. All products comply with IEC 61952:2008, ANSI, GB, and other international standards, guaranteeing consistent quality for global power infrastructure projects.

The silicone rubber pin insulators feature a one-piece injection-molded housing that exhibits excellent hydrophobicity and hydrophobic migration. This unique property allows water to bead up and roll off the surface, carrying away contaminants and significantly reducing the risk of pollution flashovers. The material also provides exceptional resistance to ozone, UV radiation, and extreme temperature fluctuations, ensuring a service life of over 30 years.
Our 11kV silicone rubber composite insulators utilize modified ECR fiberglass reinforced epoxy resin core rods with a tensile strength exceeding 1200MPa. These rods offer superior resistance to high temperatures, stress corrosion, and acid attack, while their excellent damping properties effectively absorb vibrations caused by wind and seismic activity. The end fittings are crimped using a voice-operated displacement crimper, resulting in high mechanical strength and minimal performance dispersion.
The connection points between the end fittings and core rods are fully encapsulated by the silicone rubber housing through high-temperature vulcanization, eliminating potential interface failures. An internal radial multi-seal structure further enhances sealing reliability, preventing moisture ingress and ensuring long-term internal insulation performance.
