Overview
Where the term earth clamp is common in Indian and British practice, ground clamp is the term many export buyers use. The job is the same: a connector that clamps a grounding conductor to an electrode or a metal structure, with enough contact area and bolt force to carry fault current.
Empire Alloys makes ground clamp connectors in brass, copper and gunmetal for rods, pipes and flat structures. Designs include clamps with a bolt and saddle, U-bolt clamps and lug-type clamps, and drawings from export customers are produced as specified.
Types and variants we make
Rod ground clamps
