HAIVO is a leading manufacturer of high-performance composite insulators for global power systems. Our 15KV Pin Silicone Rubber Composite Insulator for Distribution Line is engineered to deliver reliable mechanical support and electrical insulation for overhead distribution networks up to 36kV. Manufactured in compliance with IEC 61952:2008, ANSI and GB international standards, this insulator combines advanced silicone rubber technology with a high-strength fiberglass core to outperform traditional ceramic insulators in all critical performance metrics. With exceptional anti-pollution flashover capability, lightweight construction and maintenance-free operation, it is the preferred choice for utility companies, power distribution operators and electrical contractors worldwide.
Our 15kV composite pin insulators provide outstanding electrical insulation properties with a minimum creepage distance of 450mm and a lightning impulse withstand voltage of ≥120kVp. The hydrophobic silicone rubber housing effectively prevents water film formation, significantly reducing the risk of pollution flashovers even in heavily contaminated industrial and coastal areas. This translates to fewer unplanned outages, improved grid reliability and lower operational costs for power distribution systems.
The insulator features a modified ECR fiberglass reinforced epoxy resin core with a tensile strength exceeding 1200MPa, providing superior resistance to high temperature, stress corrosion and acid attack. The advanced crimping technology ensures consistent mechanical performance with minimal dispersion, making the insulator highly resistant to earthquakes, wind loads and vibration. This robust construction guarantees safe and reliable operation for decades under the most demanding environmental conditions.
The one-piece high-temperature vulcanized silicone rubber housing offers excellent resistance to ozone, UV radiation and aging, maintaining its hydrophobic properties for over 20 years. Unlike ceramic insulators that require regular cleaning and inspection, our composite insulators are virtually maintenance-free throughout their service life. This eliminates the need for costly maintenance crews and dangerous high-altitude work, resulting in a 40% reduction in total cost of ownership compared to traditional alternatives.

One-piece Silicone Rubber Injection Molding: The silicone rubber housing is formed by whole high-temperature vulcanization injection, providing excellent hydrophobicity, hydrophobicity migration and soil resistance. This effectively prevents pollution flashover accidents and ensures the safe operation of high-voltage transmission lines.
Modified ECR Fiberglass Core: The high-strength fiberglass reinforced epoxy resin rod offers superior resistance to high temperature, stress corrosion and acid attack. With a tensile strength >1200MPa, it effectively guarantees the internal insulation quality and mechanical strength of the insulators.
Voice-operated Displacement Crimping: End fittings are crimped onto the fiberglass rod using advanced voice-operated displacement type crimpers. This technology produces insulators with high mechanical strength and small dispersion of performance characteristics.
Integrated Interface Sealing: The connection between end fittings and rods is fused with the sheds housing through overall high-temperature vulcanization, minimizing interface defects and preventing moisture ingress.
Internal Radial Multi-seal Structure: The multi-layer radial sealing system effectively guarantees long-term sealing reliability at the connection between end fittings and rods, eliminating internal insulation degradation over time.
