Nowadays, it is widely used in China, and its features are convenient to install. The following is an introduction: Old-fashioned ship type clamp: This type of wire clamp wire can be used for lightning protection.we are provide fiber optical cables preformed suspension clamp,you can know it.We can guarantee the quality of fiber optical cables preformed suspension clamp.
It can withstand the installation load of the wires in the vertical span, and does not allow the clamp to slide or disengage from the insulator string when the line is in normal operation or disconnected. The load of the tower using the center clamp is large.
Pre-twisted suspension clamp function and its use: used for ADSS cable, OPGW cable, various wires, etc. in the connection of straight tower, single side overhang angle is 15 & ordm; -18 & ordm;, the combination of inner and outer spiral pre-twisted wire can be very Good protection cable, no concentrated stress, avoiding bending stress, protecting the cable and assisting vibration reduction. The complete set of suspension clamps includes: inner and outer pre-twisted wire, suspension head and matching connecting fittings. The grip strength of the clip is greater than 10%-20% of the rated tensile strength of the cable, and the installation is convenient.
Suspension clamps include hangers, U-shaped screws and hulls
Regarding the maximum deflection angle, the suspension clamp has a certain limit. When the hull is turned to an angle, the U-shaped screw will be blocked by the pylon. The maximum deflection angle is also a safe operating condition. The maximum deflection angle is related to the drape angle of the conductor or ground on both sides of the suspension point of the tower, and also depends on the diameter of the conductor and the ground wire (the outer diameter of the conductor should include the thickness of the wrapped aluminum tape or the diameter of the retaining wire). The more the screw moves up, the smaller the maximum deflection angle. If it is greater than the maximum deflection angle, measures should be taken, such as changing the double clamp, adjusting the tower height, or specially designing a new type of clamp.
