Dead-end Clamp

Product Characteristic

  • The materials of dead-end clamp differ for the matched conductors, generally, high-tensile aluminum alloy for aluminum ally conductors; aluminum-clad steel for ACSR. Dead-end clamps are used to fix conductors in the end or the middle of the overhead transmission lines. By wrapping the helical rods on a conductor, spring tension is created and the friction is produced between the conductor and rods. This fric-tion ensures a constant gripping.
  • Minimum holding strength of dead-end set not less than 95% RTS of cable.
  • Excellent anti-fatigue characteristic.
  • The installation is convenient, no special tools needed.

Consideration

  • Once installed, do not reuse after this initial installation. The hardware components may be reused as long as they are in good condition. Do not modify any compo- nents.
