Bolted locking structure delivers consistent and uniform clamping force, ensuring tight conductor contact with low contact resistance, which guarantees stable conduction of the earthing loop and effective discharge of fault current and lightning current.
Full selection of brass, hot-dip galvanized steel and high-purity copper materials adapts to earthing projects with different corrosion levels and current ratings, meeting varied requirements of lightning protection and power distribution systems.
Brass and copper feature inherent corrosion resistance; steel clamps are treated with hot-dip galvanizing for enhanced rust and aging resistance, suitable for long-term service in outdoor, humid and industrial corrosive environments.
Standard bolted design allows installation with common wrenches without special tools. Complete specifications fit various earthing conductor diameters and grounding rod sizes, enabling flexible and efficient on-site construction.
