The Conversions Tech long barrel one-hole compression lug terminates 300 MCM copper conductors in medium-voltage and heavy-current applications. The extended 2-inch barrel maximizes contact surface area for lower resistance and improved thermal performance. Engineered by Conversions Tech's US electrical team and manufactured to specification at certified partner facilities, this lug installs on 1/2-inch studs with standard compression tooling.
Typical applications include switchgear terminations, transformer connections, motor leads, and power distribution equipment where reliable high-current joints are required. The tin-plated seamless copper construction resists oxidation in industrial environments. White color coding aids phase identification during installation and maintenance.

FAQ
What compression die do I use for this lug?
Use die index I-66. Verify proper die selection with your compression tool manufacturer's chart before crimping.
Is this lug rated for medium-voltage applications?
Yes. The 35 kV voltage rating suits medium-voltage terminations. Confirm installation meets NEC and local code requirements for your specific application.
Why choose a long barrel over a standard barrel lug?
The 2-inch barrel length provides greater surface contact with the conductor, reducing resistance and improving heat dissipation for high-current connections.
