OPGW the Preformed Helical Tension Clamp The OPGW Premored/Helical Tension Clamp is primarily used to install cables with RTS less than 160 kN to tension towers/poles, corner towers/poles and terminal towers/poles. A complete set of OPGW prefabricated/spiral tensioners includes aluminum alloy or aluminum clad steel dead ends, structural reinforcement rods, support fittings and grounding clamps, etc. Wire Tension Clamp An OPGW (Optical Ground Wire) wire tension clamp is a specialized device used in the installation and maintenance of OPGW cables. OPGW cables are composite overhead cables that combine optical fibers for communication purposes with a metallic ground wire for power transmission and grounding. The OPGW wire tension clamp serves the purpose of securely attaching the OPGW cable to the supporting structure, such as poles or towers, while maintaining the necessary tension. It plays a crucial role in ensuring the stability and reliable performance of the OPGW system.
