Triple Spacer Damper


  • maintains the design spacing between subconductors under normal service conditions
  • controls the levels of aeolian vibration and subspan oscillation within the internationally accepted safety limits
  • preserves mechanical elastic and damping properties over the entire service temperature range and for the expected lifetime of the line
  • is maintenance-free for the whole lifetime of the line
  • permits movement of the subconductors in any direction without damages of spacer components and subconductors strands
  • maintains a suitable clamp grip and prevent clamp loosening by means of a safety plate and a belleville washer
  • guarantees high corona extinction voltage due to proper clamp design and manufacturing
  • withstand minimum short circuit current of 63 kA for 1 second


  • Body and clamps:
    high pressure die cast aluminium alloy
  • Rubber elements:
  • Locking latch:
    stainless steel
