This long barrel one-hole compression lug terminates 2 AWG copper conductors to 1/2-inch studs in industrial and commercial power distribution systems. The extended barrel length increases contact surface area and mechanical grip compared to standard barrel designs, reducing loosening from thermal cycling and vibration in switchgear, transformers, panelboards, and motor control centers. The electro-tin plated copper construction resists oxidation and maintains conductivity over long service life. Brown color coding provides quick wire size identification during installation and maintenance.

FAQ
What crimping tool and die are required for this lug?
Use a compression tool with hex or indent dies sized for 2 AWG long barrel lugs. The 28.7 mm barrel length requires a die set compatible with extended barrel terminals. Verify die index marks align with barrel length for full compression.
Is this lug rated for medium voltage applications?
Yes, the 35 kV voltage rating suits medium voltage terminations up to that level when used with appropriate insulation and clearances per NEC and NEMA standards. Confirm system voltage and insulation requirements with your application engineer.
Can this lug be used for both copper and aluminum conductors?
No, this lug is designed for copper conductors only. The dimensions, plating, and ampacity ratings are specified for copper cable. For aluminum conductors, specify a lug rated for aluminum or dual-rated copper/aluminum with appropriate oxide-inhibiting compound.
