Key Features
- Joins dissimilar aluminium and copper conductors in a single electrically sound connection
- Friction-welded bi-metal interface helps prevent electrolytic corrosion between aluminium and copper
- Suitable for large stranded power cables
- Factory-coated barrels help improve conductor contact during crimping
- Designed to Australian dimensions and compatible with Australian standard tooling
- Available as a reducing link from 500mm² aluminium to 120mm² copper
Professional Installation Requirements
- Installation must be performed by a licensed electrical contractor using the specified CABAC or equivalent approved crimping dies and manufacturer instructions. Confirm conductor stranding, crimp sequence and installation requirements before use.
Applications
- Joining 500mm² aluminium power cable to 120mm² copper cable
- Low-voltage power distribution systems
- Industrial switchboards and electrical infrastructure
- Cable jointing and transition connections between aluminium and copper conductors
Standards & Compliance
- AS/NZS 4325.1:1995 compression and mechanical connector requirements for copper and aluminium power cables; verify current project and regulatory requirements because the Australian edition is listed as withdrawn
Environmental Benefits
- Aluminium and copper components are recyclable at end of service life
- Enables the use of lower-mass aluminium cable while transitioning to copper cable where required
- Friction-welded construction and corrosion-resistant dissimilar-metal joining can extend connection service life and reduce replacement waste
Warranty Information
CABAC standard warranty is generally 12 months from the date of purchase for products without a product-specific warranty, subject to correct installation, use within specifications and no misuse, neglect or incorrect installation.
Available Now
Available through CABAC and authorised Australian electrical distributors; some non-standard aluminium-to-copper combinations may be machined to order.
