Key Features
  • Joins 500mm² aluminium cable to 50mm² copper cable
  • Friction-welded transition creates a mechanically strong electrical joint
  • Designed to minimise galvanic corrosion and electrolysis between dissimilar metals
  • Suitable for circular or sector-stranded aluminium cable and circular copper cable
  • Pre-engineered for installation with CABAC and compatible power crimping tools
  • Copper and aluminium barrels are clearly differentiated for correct conductor installation
Professional Installation Requirements
  • Installation must be performed by a licensed electrician or suitably qualified electrical tradesperson using the manufacturer-specified crimping tools, dies and procedures. The completed connection should be installed and tested in accordance with AS/NZS 3000 and applicable network or project requirements.
Applications
  • Low-voltage power cable joining
  • Electrical distribution and switchboard installations
  • Substation and utility cable connections
  • Industrial power and infrastructure projects
  • Transitioning large aluminium conductors to smaller copper conductors
Standards & Compliance
  • AS/NZS 4325.1: Compression and mechanical connectors for power cables with copper or aluminium conductors - test methods and requirements
  • AS/NZS 3000: Electrical installations - installation and verification requirements
Environmental Benefits
  • Aluminium and copper are recyclable materials, supporting recovery at end of service life
  • Friction-welded construction provides a durable joint that can reduce premature replacement and material waste
  • Designed to reduce electrolysis-related deterioration between aluminium and copper conductors
  • Supports repair and integration of existing aluminium and copper cable infrastructure rather than requiring complete cable replacement
