This preformed suspension clamp/Cable Clamp is to hang ADSS and OPGW cable on the towers (poles). It is usually installed on straight towers (poles) and towers (poles) with a line angle less than 25°. The clamp can reduce the static stress and increase the anti-vibration ability of the cables on the suspension point. It also overcomes the dynamic stress of wind-force vibration and guarantees max crooked radius of the optical fiber cable. There are many types according to different cable diameter.
