Self-locking Structure Of Wedge-type Tension Clamp

During the installation process, the relative positions of the body of dead end clamp and the wedge should be correctly positioned. ab cable dead end clamp consists of a main shell, upper and lower wedge-shaped clamps, etc. After the wire is placed between the clamps, the external force pushes the wedges into the shell, causing shearing and compression changes on the contact surface. This process gradually strengthens the bond between the wedge and the wire as the wire tension changes, making it more difficult for the wire to disengage from the wedge cavity under tension.

The self-locking characteristic stems not only from the geometric wedge configuration but also from the frictional interaction between the wire and the wedge surface. When the load is transferred to the wedge assembly, a component force is generated in the direction of wedge movement, further increasing the contact pressure.
