This long barrel one-hole compression lug terminates 250 MCM conductors to 3/8-inch studs. The extended barrel length increases contact surface area for high-current industrial and commercial applications where mechanical integrity and low resistance are critical. Electro-tin plating provides oxidation resistance during installation and service life.

FAQ
What crimping tool is required for a 250 MCM long barrel lug?
Use a hydraulic crimping tool with dies rated for 250 MCM copper compression terminals. The long barrel requires multiple crimps per manufacturer die specifications; verify die compatibility with your tool model.
Is this lug suitable for 35kV medium-voltage applications?
The 35 kV voltage rating applies to the lug insulation rating when used with appropriate stress relief and insulation systems. Confirm overall assembly rating with your cable and termination kit specifications.
Why choose a long barrel over a standard barrel lug?
The 1.688-inch barrel length provides greater surface contact area and improved mechanical retention under vibration and thermal cycling. Long barrel designs are often specified for critical connections in substations and heavy industrial environments.
