The 11kV polymer disc insulator is made of high-quality hydrophobic silicone rubber, which exhibits excellent resistance to pollution flashover and maintains electrical insulation performance under harsh environmental conditions. The inherent waterproof (hydrophobic) properties of the silicone rubb.
Product Detail
The 11kV Suspension Polymer Insulator is designed for medium-voltage overhead transmission and distribution systems, providing reliable electrical insulation and strong mechanical support for conductors under outdoor operating conditions.
Compared with traditional porcelain insulators, polymer suspension insulators offer:
Better pollution resistance
Lightweight installation
Higher impact resistance
Lower maintenance requirements
Improved long-term reliability
These advantages make 11kV composite suspension insulators widely used in:
Utility power distribution networks
Rural electrification projects
Industrial substations
Renewable energy transmission systems
Utilities and EPC contractors increasingly prefer composite suspension insulators because they solve many common field problems associated with porcelain and glass insulators.
The HTV silicone rubber housing provides superior hydrophobicity, helping prevent:
Leakage current
Flashover
Surface contamination buildup
Coastal environments
Industrial pollution zones
High-humidity regions
Desert and dusty areas
Polymer insulators are significantly lighter than porcelain insulators.
Easier transportation
Faster installation
Reduced labor cost
Lower tower mechanical load
This is especially valuable for remote transmission projects and mountainous installations.
The fiberglass reinforced epoxy core rod provides:
Excellent tensile strength
High mechanical reliability
Long-term structural stability
Wind load conditions
Ice load environments
Continuous conductor tension
