700 MCM Copper Long-Barrel Two-Hole Compression Lug – 1/2" Stud, 1.75" Spacing | Red | Conversions Tech™
The Conversions Tech™ 700 MCM Long-Barrel Two-Hole Compression Lug is a precision-engineered connector designed for high-ampacity terminations in utility, renewable energy, and industrial power-distribution systems. Manufactured from seamless C11000 electrolytic-grade copper and finished with an electro-tin coating, this lug provides exceptional conductivity, corrosion resistance, and vibration-proof performance. Its extended long-barrel design ensures dual crimps that meet UL pull-out requirements while maintaining ultra-low resistance across demanding electrical installations.
Rated for 600 V to 35 kV and -40°C to +90°C, this lug is UL Listed and RoHS Compliant, making it an ideal solution for mission-critical grounding, bus connections, and high-current applications.
Key Performance Features
- Premium C11000 Copper: < 0.04 Ω·mm²/m resistivity ensures superior conductivity and minimal energy loss.
- Electro-Tin Plating: Provides excellent oxidation resistance and improved solder flow for high-performance terminations.
- Long-Barrel Design: 2.875 in barrel accommodates dual Anderson-style crimps for maximum strength and heat dissipation.
- Dual 1/2" Stud Holes: 1.75" center-to-center spacing conforms to NEMA drilling standards.
- Chamfered Cable Entry: Guides 700 MCM (750 kcmil) conductors smoothly into place, preventing strand splay.
- Wide Voltage & Temperature Rating: UL listed for 600 V–35 kV and operational between -40°C to +90°C.
