Key Features
- Joins 4-core sector aluminium cable to circular copper cable
- Friction-welded aluminium-to-copper transition helps provide a strong, electrically sound joint
- Designed to reduce electrolysis between dissimilar metals
- Fully annealed construction for improved ductility
- Suitable for power distribution, mains, submains, switchboard and infrastructure applications
- Compatible with correctly matched CABAC or equivalent approved crimp tooling and dies
Professional Installation Requirements
- Installation must be performed by a licensed electrical contractor using the manufacturer's specified V-shaped nest die, 13-tonne or larger indentor tool, correct crimp sequence and applicable electrical installation procedures. The completed connection should be insulated and tested as part of the finished cable system.
Applications
- Low-voltage mains and submains cable connections
- Commercial and industrial power distribution
- Switchboard and electrical equipment terminations
- Utility and infrastructure cable installations
- Transition joints between aluminium sector cable and copper conductors
Standards & Compliance
- AS 4325 Part 1 for compression and mechanical connectors for copper or aluminium power cables, as stated by CABAC; verify the current nominated standard and utility authority requirements before installation
Environmental Benefits
- Aluminium and copper components are highly recyclable at end of service life
- Friction-welded construction can improve joint durability and reduce premature replacement waste
- Reduced electrolysis risk may extend the service life of mixed-metal cable connections
- Long-life electrical connectivity can reduce maintenance-related material consumption
