Conversions Tech Copper Compression Lug – 1 AWG, 1/2" Stud (Non-Tinned / Bare Copper)
The Conversions Tech Copper Compression Lug is a seamless tubular, heavy-duty electrical connector engineered for 1 AWG copper conductors and a 1/2" stud termination. Manufactured from high-purity bare (non-tinned) copper, this lug delivers low electrical resistance, excellent current-carrying capacity, and dependable mechanical strength for high-current power distribution in controlled or indoor environments.
- 1 AWG copper conductor range for high-current applications
- 1/2" stud ring tongue for robust bolted terminations
- Seamless tubular barrel for uniform compression and gas-tight joints
- Bare copper (non-tinned) construction for maximum conductivity
- Rated up to 600V for AC and DC power distribution
- Designed for vibration and thermal cycling environments
High-Current 1 AWG Copper Lug for 1/2" Stud Terminations
This 1 AWG copper compression lug features a seamless tubular barrel that compresses evenly around the conductor, forming a gas-tight electrical interface with minimal contact resistance and strong pull-out strength. This construction ensures reliable long-term performance in demanding electrical systems.
The 1/2" stud interface is commonly used on battery banks, bus bars, grounding points, inverters, and industrial distribution equipment where higher mechanical strength and larger hardware are required. The non-tinned copper finish makes this lug ideal for controlled indoor or protected electrical environments.
Key Features
- Seamless tubular copper barrel ensures consistent crimp performance
- Non-tinned (bare) copper for maximum electrical conductivity
- Designed for 1 AWG copper conductors
- 1/2" stud hole for secure bolted electrical connections
- 600V maximum voltage rating
- High mechanical strength suitable for vibration and thermal cycling environments
