Company celebrates 70th anniversary

Mayfield Village, Ohio, April 26, 2017 — Platinum is the traditional gift for a 70th anniversary. Known for ductility, endurance and quality, platinum also may be the best substance to commemorate Preformed Line Products (PLP), celebrating its 70th anniversary this year.

Ductility. Forming wire is what PLP knows best. Since 1947, when electrical engineer Thomas F. Peterson devised an innovative way to secure conductors, we’ve been developing and manufacturing product solutions for electric power utility and telecommunication industries.

Peterson’s helical preformed rods, which could hold fast to a conductor without end clamps and protect it from abrasion and fatigue, launched an ever-growing line of patented products and brands. Today, PLP’s products — including cable anchoring and control hardware and systems; fiber optic and copper splice closures; and high-speed cross-connect devices — also serve cable and broadband service providers, solar energy markets and other specialized niches.

Endurance. PLP has weathered seven decades of advancing technology, changing industry regulations and increasing customer demands. And we’ve become stronger than ever, expanding from one facility in Cleveland, Ohio, to 21 facilities worldwide, with more than 2,600 employees. Our wholly owned international subsidiaries serve customers in more than 100 countries.

Quality. As we’ve grown, we’ve remained committed to:

  • Designing and developing technically superior products
  • Maintaining our industries’ standards of excellence
  • Ensuring durability and performance standards through rigorous laboratory and field testing

Our first Research and Engineering Center, built in the 1950s, was a cutting-edge facility where technicians and engineers could simulate outdoor conditions in-house. Relocated, expanded and updated through the years, PLP’s current laboratory and testing facility remains one of the most sophisticated in the U.S.

“For 70 years, PLP has provided customers with affordable, high-quality products, delivered where needed, when needed,” says Robert G. Ruhlman, Chairman and Chief Executive Officer. “Demands and markets will continue to change, but PLP will continue to anticipate needs globally and reach new milestones in product innovation and customer support.”
