The 20kV high voltage composite insulator is a crucial component developed for power transmission and distribution systems. It is primarily used on medium-voltage overhead lines and distribution networks to support conductors and isolate voltage, preventing arc breakdown. Manufactured with advanced composite materials, this insulator ensures excellent electrical and mechanical performance even under harsh environmental conditions.
This insulator consists of three main parts: a fiberglass reinforced plastic (FRP) core, silicone rubber sheds, and metal end fittings. The FRP rod offers superior tensile and fatigue resistance; the silicone rubber sheds provide excellent hydrophobicity and anti-pollution flashover resistance; the metal fittings are hot-dip galvanized for corrosion resistance and secure connections. The overall design is compact, lightweight, and highly durable.

Superior Insulation Performance: Silicone rubber sheds offer excellent hydrophobicity and high anti-pollution performance.
Lightweight & Easy Installation: Significantly lighter than porcelain insulators, reducing labor and transport costs.
Excellent Weather Resistance: Resistant to UV rays, chemicals, and aging - ideal for extreme conditions.
High Mechanical Strength: FRP rod ensures strong structural support, ideal for areas with heavy wind or snow loads.
Environmentally Friendly: Non-toxic and non-polluting, meeting global environmental standards.
This product is widely used in urban and rural power grids, high-speed railway systems, wind and solar power transmission lines, and more. It is especially suitable for high-altitude, coastal, and polluted areas as an ideal replacement for traditional ceramic insulators.
We offer flexible customization options, including insulator length, mechanical load, shed diameter, pollution resistance level, and more. Custom orders based on client drawings are welcome, and OEM/ODM services are available to meet diverse market demands.
