Suspension Units

TNHSA – Made from Aluminium Alloy with Neoprene inserts for AAC, AAAC & ACSR Conductor

Helical Suspension Units reduce the wear and fatigue on conductors.  They reduce static stresses at suspension points and provide greater protection to conductors than Line Guards and Armour Rods.

This range of Helical Suspension Units is good for use on  line angles up to and including 30° and, with double units, up to 60°.
 
Materials used in this range
  • Bolt and nut – Galvanised steel
  • Split pin – Stainless steel, humpback
  • Strap – High strength Aluminium Alloy
  • Neoprene insert – Aluminium Alloy reinforcement moulded into the neoprene
