Bi-Metal Copper Aluminium Lug Blank suits to 300mm² cable BL300-BL HBT300-BL

Bi-Metal Copper Aluminium Lug Blank suits to 300mm² cable BL300-BL HBT300-BL

Key Features

• Manufactured using a friction welding process, ensuring a very strong and electrically sound joint.
• Suitable for aluminium conductors and copper terminals or busbars.
• Crimp from the palm end to force the compound into conductor strands.
• Barrel filled with crimping compound and sealed with a cap.
• Crimping positions (AF) are clearly marked on the barrel.

Designed for Stranded Sector and Circular Stranded Aluminium Conductors, the CABAC range of Bi-Metal Lugs is made from the highest quality materials:

• Aluminium (99.6%)
• Copper (99.9%)

These materials are joined using a friction welding process, which produces a very strong, electrically sound joint that is not subject to electrolysis. The barrel is chemically treated to reduce contact resistance and corrosion and is filled with a jointing compound that breaks the oxide layers on the aluminium.

Crimping Instructions

• The lug should be crimped from the palm end first to force the joint compound into conductor strands.
• Designed to be crimped using standard Australian tooling with normal aluminium hexagonal dies.

Standards and Compliance

• AS/NZS4325 Part 1
