Copper Long-Length Compression Splice — 4/0 AWG (≈212 MCM) | Tin-Plated | Conversions Tech
The Conversions Tech Copper Long-Length Compression Splice is a rugged, high-conductivity connector engineered for 4/0 AWG (≈212 MCM) copper conductors. Designed for feeders, switchgear, and industrial power distribution, its seamless, tin-plated copper barrel with a centered wire stop ensures low resistance, multi-crimp reliability, and long-term mechanical strength. This professional-grade splice is built to maintain performance in demanding electrical environments.
Rated for up to 35 kV and 90°C, this splice is UL Listed and RoHS compliant, providing unmatched safety and compliance across industrial and utility-grade installations.
Key Features
- Long-Length Barrel: Provides extra crimping surface for maximum pull-out strength and superior heat dissipation.
- Seamless Copper Tube: Smooth internal diameter with chamfered entry ensures consistent wire insertion and crimping.
- Tin-Plated Finish: Offers corrosion resistance and enhanced conductivity for both indoor and outdoor use.
- Purple Color Code: Simplifies gauge identification during field installations.
- High Voltage & Temperature Rating: Supports up to 35 kV and 90°C operating conditions when properly installed.
- Certified Quality: Fully UL Listed and RoHS Compliant for global electrical standards.
