CABAC CU LUG 500MM2 CABLE BLANK CAL500LB x 1/EACH

Description

High-Conductivity Performance for Heavy-Duty Terminations

Built for serious electrical work, this 500mm² copper long barrel lug delivers outstanding conductivity and consistent performance on high-load circuits. Manufactured from 99.9%+ high-conductivity copper, it ensures minimal resistance and efficient current flow—critical for high voltage terminations and demanding industrial environments.

The extra-long barrel design allows for multiple crimps, giving you stronger mechanical retention and improved electrical contact where it matters most. Whether you’re terminating large cables on switchboards or working on high-stress connections like drop-out fuses, this lug helps maintain system integrity under load.

Outdoor Reliability with Sealed Protection & Compliance

Designed specifically for external applications, this outdoor-style copper lug features a sealed palm to prevent moisture ingress—reducing the risk of corrosion and premature failure. With no inspection window and a fully annealed copper body, it offers durability and flexibility during installation, even in challenging site conditions.

Tin electroplating adds another layer of protection, enhancing corrosion resistance while maintaining conductivity. Manufactured to meet major international standards including AS4325, IEC, DIN/VDE, JIS, BS, and NEMA, this lug supports compliant installations across residential, commercial, and industrial projects.

Trade-Friendly Design for Faster Installs

On-site efficiency matters, and this long barrel lug is designed to keep jobs moving. Compatible with standard hexagon dies (shared with common lug ranges), it integrates seamlessly into your existing tooling setup—no need for specialised equipment.

The extended barrel also provides extra length for heat shrink application, helping you achieve a clean, airtight seal with minimal rework. Interchangeable tooling compatibility with CABAC, Utilux, and Burndy further simplifies procurement and installation, saving time across multiple jobs.
