What is a tension clamp for ACSR Rabbit conductor?

2025-08-16

A tension clamp, also called a dead-end clamp, is a type of fitting used to terminate an overhead conductor at a support structure. Its main purpose is to securely grip the conductor and transfer its full tensile load to the tower or pole. The clamp must be robust enough to withstand the maximum operating tension of the line.

The ACSR Rabbit conductor is a specific type of Aluminum Conductor Steel Reinforced cable. It is widely used for power distribution lines. Its key specifications are:

  • Nominal Aluminum Area: 50 mm²

  • Stranding: 6 aluminum strands over 1 steel strand (6/1)

  • Overall Diameter: 10.05 mm

  • Approx. Weight: 214 kg/km

  • Approx. Breaking Load: 18.4 kN or 1835 daN

A tension clamp designed for ACSR Rabbit must have a precisely matched groove diameter to fit the conductor's 10.05 mm diameter.
