66kV to 765kV Long Rod Composite Insulators – Product Description
Our 66kV to 765kV Long Rod Composite Insulators are specially designed for high-voltage and extra-high-voltage transmission lines, ensuring superior electrical performance and mechanical reliability. Built with advanced composite technology, these insulators feature a high-strength fiberglass core rod encased in premium silicone rubber housing, providing excellent insulation and long-term durability.
The aerodynamic shed design enhances creepage distance and ensures outstanding resistance against pollution, moisture, and environmental contaminants. The hydrophobic nature of the silicone rubber surface minimizes leakage current and reduces the risk of flashovers, even in harsh weather conditions such as heavy rain, fog, or industrial pollution.
These long rod insulators are lightweight compared to conventional porcelain insulators, making transportation, handling, and installation easier and more cost-effective. They also offer high tensile strength, excellent resistance to UV radiation, and superior performance under extreme temperature variations.
Widely used in overhead transmission systems ranging from 66kV to 765kV, these insulators are suitable for use in substations, transmission towers, and power grids. Their robust construction and low maintenance requirements ensure long service life and enhanced reliability, making them an ideal solution for modern power infrastructure.
