Applications
  • Joining large aluminium power cables to smaller copper conductors
  • Electrical distribution and power cable transition joints
  • Switchboard, industrial and utility cable installations
  • Reducing joints, fly leads and cable tails where aluminium-to-copper transition is required
Standards & Compliance
  • Designed and manufactured to the requirements of AS/NZS 4325.1 for compression and mechanical connectors for power cables with copper or aluminium conductors
Environmental Benefits
  • Aluminium and copper components are recyclable at end of service life
  • Friction-welded construction and corrosion-resistant transition help extend connection service life and reduce replacement waste
  • Jointing compound helps limit aluminium oxidation, supporting reliable electrical performance over time
