  • Friction-welded aluminium-to-copper joint designed to minimise electrolysis risk
  • Manufactured from high-purity aluminium and copper materials
  • Suitable for cable jointing and power-distribution applications
  • Requires the specified V-shaped crimp nest and suitable 13-tonne or larger indentor tool
  • Designed to conform to Australian and international connector requirements
Professional Installation Requirements
  • Installation and crimping should be carried out by a licensed electrical contractor using the manufacturer's specified crimping dies, tooling and installation instructions. Verify cable preparation and connection requirements against the applicable wiring and utility authority requirements.
Applications
  • Joining 240 mm² 4-core sector aluminium cable to 300 mm² copper cable
  • Low-voltage power cable jointing
  • Electrical distribution and switchboard installations
  • Industrial, commercial and utility power networks
  • Aluminium-to-copper cable transitions where galvanic corrosion control is required
Standards & Compliance
  • AS/NZS 4325.1 for compression and mechanical connectors for power cables with copper or aluminium conductors
  • CABAC documentation also references IEC, DIN/VDE, JIS and BS connector requirements
Environmental Benefits
  • Aluminium and copper components are recyclable at end of service life
  • Friction-welded construction helps reduce electrolysis-related failures and premature replacement
  • Durable metal construction can extend connection service life and reduce material waste
  • Supports efficient power-distribution systems through a low-resistance aluminium-to-copper transition
