High Voltage Overhead Line Composite Suspension Insulator is an essential component in modern power transmission systems. It is mainly used in high-voltage overhead lines to provide mechanical support and insulation for conductors. Compared to traditional porcelain insulators, composite insulators are lightweight, pollution-resistant, and offer superior mechanical strength, making them a preferred solution for modern power projects.
The insulator consists of three main parts:
A fiberglass reinforced epoxy resin rod (core)
A silicone rubber weather shed
Galvanized steel end fittings
The fiberglass rod provides high tensile strength, while the silicone rubber housing ensures excellent hydrophobicity and pollution resistance. The end fittings are hot-dip galvanized for corrosion resistance and long-term durability.

| Insulation Distance | 500mm - 1500mm (customizable) |
| Pollution Class | Class II / III / IV |
| Operating Temperature | -40ºC to +55ºC |
| Overall Length | Customized |
| Standard Compliance | IEC 61109 / GB/T 19519 |
Superior Pollution Resistance: Silicone rubber sheds resist dirt and maintain performance in harsh conditions.
High Mechanical Strength: Strong fiberglass core supports heavy mechanical loads, suitable for long-span applications.
Lightweight & Easy Installation: 50% lighter than porcelain, simplifying transportation and installation.
Excellent Aging Resistance: Performs well in coastal, mountainous, and industrial areas.
Explosion-Proof Design: Safe even in case of breakage-no shattering risk.
Composite suspension insulators are widely used in high-voltage transmission lines ranging from 66kV to 220kV. Ideal for use in mountainous terrains, coastal zones, polluted regions, and areas with extreme temperatures. Also suitable for wind/solar grid integration, long-distance power lines, and urban substations.
