Key Features
- Joins 3-core sector-shaped aluminium cable to circular copper cable
- Friction-welded aluminium-to-copper transition designed to resist electrolysis
- Manufactured from high-conductivity aluminium and copper
- Suitable for power cable jointing and termination applications
- Designed for use with CABAC and compatible 13-tonne or larger compression tooling
- Sector cable geometry supports connection to large aluminium distribution cables
Professional Installation Requirements
- Installation must be performed by a licensed electrical contractor using the manufacturer-specified compression dies, crimp sequence and cable preparation procedure. The completed connection should be installed and tested in accordance with applicable wiring rules, network requirements and manufacturer instructions.
Applications
- Joining 3-core sector-shaped aluminium power cable to copper conductors
- Electrical distribution and switchboard connections
- Underground power cable jointing and transition connections
- Utility, industrial and commercial power installations
Standards & Compliance
- AS/NZS 4325.1:1995 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 helps reduce electrolysis-related failure and replacement waste
- Long service life can reduce maintenance frequency and material consumption
- Enables the use of aluminium conductors, which can reduce conductor material mass compared with equivalent copper cable systems
