Selection Of Line Tension Clamps When Using Insulated Conductors As Wedge-type Tension Clamps

Selection of line dead and clamp when using insulated wires

Compared with bare wires, insulated wires have the advantages of high safety and reliability, reduced line loss, and less wire corrosion. When using insulated wires, we need to pay attention to the fact that dead clamp is clamped on the outer diameter of the "wire" rather than the outer diameter of the "conductor" when used, so the dead end clamp overhead line model used should be selected based on the outer diameter of the wire rather than the outer diameter of the conductor.

In addition, when installing dead end clamp with eye hook, we must tighten the screws evenly, requiring that there is no increase in wire stress at the contact surface between the installed wire and the original metal, so as to prevent the wire from being damaged by breeze vibration or other wire oscillations and ensure that the grip force of dead end loop clamp on the wire is not less than 95% of the wire breaking force.
