Helical Preformed Suspension Clamp for OPGW Optical Ground Wire

This dedicated helical suspension clamp is designed for OPGW power optical cable. It provides reliable hanging and support on straight-line towers, evenly transmits axial load and disperses radial stress. It prevents excessive cable bending and stress concentration, with clamping grip over 18% of cable rated tensile strength. Features outstanding anti-fatigue and auxiliary vibration damping performance, effectively protecting the cable and greatly extending service life.
