CABAC BI-METAL STALK 50MM2 CABLE BS50/12 x 1/EACH

Description

Built for Reliable Aluminium to Copper Cable Connections

When terminating aluminium conductors to copper busbars or equipment, the CABAC BI-METAL STALK 50MM2 CABLE BS50/12 provides a dependable, high-performance solution. Designed specifically for 50mm² stranded sector and circular stranded aluminium cable, this bi-metal stalk lug ensures efficient current transfer while minimising resistance at the joint.

Manufactured using high-purity aluminium and copper, the lug delivers excellent conductivity and strong mechanical performance under load. The aluminium sleeve provides secure cable termination, while the copper palm ensures a solid connection point for switchgear, panels, and distribution equipment.

With a fully annealed metal state and friction-welded join, the lug maintains structural integrity during crimping and installation, helping electricians achieve reliable terminations that perform consistently across demanding commercial and industrial environments.

Trade-Grade Quality with International Compliance

CABAC bi-metal stalk lugs are built for professional electrical installations where compliance and durability matter. Each lug is friction welded using IEC-standard processes, creating a strong metallurgical bond between the aluminium barrel and copper palm. This construction helps prevent galvanic corrosion and ensures long-term electrical stability.

To support reliable installations across different project specifications, the lugs comply with recognised international standards including AS/NZS4325 Part 1, along with IEC, DIN/VDE, JIS, and BS requirements. This makes them suitable for use across a wide range of electrical infrastructure projects where compliance with recognised standards is essential.

The barrel is pre-coated with jointing compound, improving contact and reducing oxidation during installation. Each lug is also individually packed, helping keep components clean and protected until they’re ready to be used on site.

Designed for Fast, Efficient Trade Installations

For electricians working to tight project timelines, compatibility and ease of installation are critical. The CABAC BS50/12 bi-metal stalk lug is manufactured to Australian dimensions, allowing it to be crimped using standard Australian tooling commonly used by electrical contractors. This eliminates the need for specialised equipment and keeps installations moving quickly on site.

With a full range of sizes available across the CABAC lineup, electricians can maintain consistent termination standards across multiple cable sizes in switchboards, meter panels, and industrial distribution systems. Where unique project requirements arise, stalks can also be machined to order, providing additional flexibility for specialised installations.

For contractors managing commercial builds, maintenance upgrades, or industrial switchboard work, these lugs deliver the reliability and compatibility needed to keep jobs progressing without delays.
