Preformed Line Products - Company Profile Brochure

In 1947, Thomas F. Peterson, an electrical engineer in the USA, came up with an innovative idea that became the catalyst to forming a worldwide organization that would ultimately grow into an international company with operations in seventeen countries. Responding to a customer’s concern about conductors breaking at the point of support, Peterson thought of preforming rods into a helix having an inside diameter somewhat smaller than the outside diameter of the conductor. The theory was that helically preformed rods, when applied over conductor, could provide a secure fit without end clamps, as well as ‘armor’ to protect the conductor from abrasion and fatigue at points of attachment. This idea proved successful and the product was called the PREFORMED™ Armor Rod, patented in 1954. Armor Rods offer superior reinforcement and protection advantages over conventional wire and clamping methods. The helical concept then grew into a complete line of products for the electric power utility and communications industries.
