PLPC

Preformed Line Products Company

A maker of cable and wire support, protection, and connectivity hardware for the world's power grids and communications networks. Its helical, clamp-free grips, closures, and accessories keep electricity and data flowing for utilities, telecoms, and 5G and fiber projects, along with solar mounts and EV charging foundations. Founded in 1947 by engineer Thomas Peterson, the company took its name from its first product, the PREFORMED Armor Rod, a helix that wraps around conductors like a glove to stop them breaking at support points.
