CABAC BI-METAL STALK 500MM2 CABLE BS500/18 x 1/EACH

Description

Built for High-Capacity Aluminium Cable Connections

The CABAC BI-METAL STALK 500MM2 CABLE BS500/18 is designed for reliable termination of large aluminium conductors in demanding electrical installations. Manufactured for 500 mm² stranded sector and circular stranded aluminium cables, this bi-metal lug provides a dependable connection point between aluminium cable and copper busbars or equipment terminals.

The friction-welded construction combines 99.6% pure aluminium sleeves with a 99.95% pure copper palm, ensuring excellent conductivity while preventing galvanic corrosion between dissimilar metals. For electricians working on high-current distribution systems, this design delivers stable electrical performance and long-term reliability.

Each lug barrel is pre-coated with jointing compound, helping improve contact performance and reduce installation time on site. With standard Australian dimensions and compatibility with common crimping tools, installation is straightforward—helping keep large cable terminations quick and efficient during switchboard or infrastructure work.

Proven Reliability with International Standards Compliance

When working on commercial or industrial projects, compliance and consistent performance are essential. The CABAC BI-METAL STALK 500MM2 CABLE BS500/18 is manufactured to meet recognised international standards, giving contractors confidence that installations will meet project specifications and safety requirements.

These bi-metal stalk lugs are friction welded in accordance with IEC standards, creating a strong metallurgical bond between aluminium and copper components. The fully annealed metal structure improves ductility and durability, helping the lug maintain reliable mechanical and electrical performance even under demanding site conditions.

Compliance with AS/NZS4325 Part 1, IEC France, DIN/VDE Germany, JIS Japan, and BS United Kingdom standards ensures the lug is suitable for a wide range of electrical infrastructure and industrial installations. With an operating temperature range of –40°C to +125°C, it performs reliably in harsh environments where electrical systems must remain stable year-round.

Trade-Ready Installation for Contractors and Switchboard Builders

Large cable terminations can quickly slow down an install if components aren’t built for trade efficiency. The CABAC BI-METAL STALK 500MM2 CABLE BS500/18 is designed to simplify installation while maintaining consistent quality across projects.

Each lug is individually packaged to keep the barrel clean and protected before installation. The pre-applied compound and compatibility with standard Australian crimping tools mean electricians can terminate cables quickly without requiring specialised tooling.

With availability across a wide range of sizes—and the option for machined stalks for specific project requirements—these lugs provide flexibility for switchboard builders, industrial electricians, and contractors working on large-scale power distribution projects.

For trades needing dependable cable terminations backed by recognised standards, CABAC bi-metal stalk lugs deliver a proven solution that helps keep projects moving without compromise.
