Masterful "preformances" are expected from Preformed Line Products by its audience in the energy and communications industries. The company designs and manufactures components and systems used by utility crews and others to construct, repair, and maintain overhead and underground networks for energy, communications, and broadband network companies. It provides formed wire products (for maintenance and repair of aging plant infrastructures), protective fiber-optic closures and splice cases, solar hardware, and data communication interconnect devices and enclosures for data communications networks. Chairman Robert Ruhlman and his family own almost 80% of the company.
