OPGW Grounding Downlead Clamp is a utility-grade grounding accessory designed for safe and controlled routing of Optical Ground Wire (OPGW) from overhead transmission lines down to poles, towers, or splice enclosures. It ensures a continuous and reliable grounding path that safely dissipates induced voltage and lightning surges without affecting the optical communication performance.
Engineered for modern power and telecom infrastructure, the clamp plays a critical role in protecting fiber optic networks integrated within power transmission systems. It prevents electrical stress build-up on OPGW while maintaining full signal integrity, ensuring uninterrupted communication and system reliability.
Manufactured from high-strength, high-conductivity aluminum alloy, the clamp offers excellent mechanical stability and electrical performance under demanding field conditions. The use of stainless steel hardware enhances corrosion resistance and ensures long-term durability even in harsh outdoor environments such as coastal, industrial, or high-moisture areas.
Its advanced dual-side grounding configuration provides a secure and balanced connection on both legs of the OPGW, improving safety and reducing the risk of uneven electrical loading. The design also supports flexible installation on poles and structures, making it suitable for a wide range of transmission line configurations and utility applications.
Built for reliability and performance, the OPGW Grounding Downlead Clamp ensures safe energy dissipation, structural stability, and long service life in critical power transmission and fiber optic communication networks.
