APG Type Parallel Groove Clamp

APG Type Parallel Groove Clamps are mechanical connectors designed to securely join or tap aluminum conductors in overhead power distribution and electrical transmission systems. The parallel groove design provides a large contact area between conductors, ensuring low contact resistance, excellent electrical conductivity, and a reliable mechanical connection. The clamp is fastened with high-strength bolts, allowing quick installation without the need for crimping tools.
APG clamps are widely used for conductor splicing, branching, and tap connections in utility networks, substations, industrial power systems, and overhead line installations.
