Structural Components Of Suspension Clamp Connection Device

The suspension of overhead conductors on towers requires reliable mechanical connections. suspension clamp for lt ab cable. Fixing is achieved to the insulator string via a hanging ring or plate. This connection device uses a ball-head hanging ring design, allowing the conductor to swing at a certain angle under wind load. The inner diameter of the hanging ring precisely matches the connecting pin of the insulator string. During assembly, simply slip the hanging ring onto the pin and insert the cotter pin to complete the fixation.

The suspension clamp connection device includes two upper and lower arc-shaped clamps, and the inner side of the clamps is provided with an arc groove that matches the outer diameter of the wire. When installing fiber suspension clamp, place the wire in the arc groove of the lower clamp, and then tighten it with U-bolts through the ear plates on both sides after covering the upper clamp. The torque value of the bolts needs to be controlled within the specified range; too loose will cause conductor slippage, while too tight may damage the conductor surface. The contact area between the clamping plate and the conductor directly affects the gripping force distribution; therefore, the arc grooves must be precision machined during manufacturing.
