The Conversions Tech Copper Long Barrel Compression Lug is engineered for terminating 350 MCM copper conductors in high-current industrial, utility, and renewable-energy installations. The single-hole design with 3/8-inch stud size interfaces with standard busbars, switchgear terminals, and distribution hardware. Long-barrel construction maximizes crimp contact area for lower resistance and superior mechanical retention under heavy electrical loads.

FAQ
What crimping die is required for this lug?
Use the I-71 die index with your compression tool to achieve proper crimp geometry and UL-recognized termination.
Is this lug rated for medium-voltage applications?
Yes. The 35 kV voltage rating supports medium-voltage distribution circuits, switchgear terminations, and utility infrastructure.
Why does the barrel length matter for 350 MCM conductors?
The 2-inch long barrel provides increased contact surface area for the compression crimp, reducing resistance and improving mechanical stability compared to short-barrel designs.
