CABAC COPPER BARRIER LINK 300MM2 CASB300 x 1/EACH

Description

Reliable Moisture & Oil Barrier Performance

Built for demanding cable jointing applications, the CABAC Copper Barrier Link 300mm² delivers a secure, impermeable barrier against oil and moisture ingress. Designed specifically for use with paper insulated cables, it helps maintain insulation integrity and prevents contamination that can lead to premature cable failure.

With high-conductivity annealed copper (99.7% IACS), this barrier link ensures efficient current flow while maintaining structural strength during installation. The fully annealed construction also provides the ductility needed for consistent, clean terminations on-site—reducing the risk of cracking or deformation during crimping.

Trade-Grade Quality with Proven Compliance

Manufactured from 99.95% pure copper and engineered to meet multiple international standards, this copper barrier link gives confidence on both compliance and durability. It’s suitable for use across a wide range of commercial and industrial projects where adherence to standards is non-negotiable.

Rated for operating temperatures from -55°C to 100°C, it performs reliably across harsh Australian site conditions—from underground infrastructure to exposed industrial environments. With strong tensile properties and controlled oxygen content, it offers consistent performance across batches, helping maintain quality across large-scale jobs.

Designed for Efficient Trade Installation

Time on site matters. The CABAC CASB300 barrier link is designed with trade efficiency in mind, featuring tooling compatibility with major systems including Cable Accessories, Utilux, and Burndy. This means no need to switch tooling—keeping installs moving and reducing downtime.

The 300mm² capacity and precise internal diameter ensure a proper fit for large conductors, supporting clean, consistent terminations across multiple jobs. Clear installation guidance—such as avoiding crimping near the centre barrier—helps prevent damage and ensures reliable performance every time.

Whether you’re working on infrastructure upgrades, industrial maintenance, or large commercial installs, this barrier link supports faster installs with fewer complications.
