Hook Type Grounding Block for Transmission Line Stringing | Galvanized Steel, Reliable Earthing Protection

Product Overview

The Hook Type Grounding Block is a professional grounding device designed for overhead transmission line stringing, conductor installation, and power line maintenance. It provides a reliable temporary grounding path during conductor, earth wire, or pilot wire stringing operations, helping discharge induced current and static electricity to improve personnel safety and protect valuable conductors.

Featuring a robust galvanized steel frame with a triple-roller hook-type structure, this grounding block ensures smooth conductor travel while maintaining continuous electrical grounding throughout the stringing process. It is widely used by power utilities, EPC contractors, transmission line builders, and electrical maintenance companies.

Manufactured from high-strength steel with precision-machined rollers, the Hook Type Grounding Block delivers excellent mechanical durability, corrosion resistance, and stable grounding performance in demanding outdoor environments.
