Thomas & Betts 54820 Two-Way Long Barrel Compression Splice

Description:

The Thomas & Betts 54820 Copper Two-Way Long Barrel Compression Splice is used to permanently join two 600 kcmil copper conductors in high-current power distribution and grounding systems. Commonly installed in electrical substations, switchgear, transformers, utility networks, power generation facilities, and heavy industrial electrical installations, this long-barrel electro tin-plated copper splice provides a reliable, low-resistance electrical connection with high pull-out strength. Maintenance teams and system integrators use this connector for repair, retrofit, expansion, and replacement of large copper conductor splice assemblies.

Applications:

The Thomas & Betts 54820 is designed for splicing two 600 kcmil copper conductors in medium-voltage and low-voltage power distribution, grounding, and bonding applications. Its long-barrel Color-Keyed® compression design ensures maximum conductor contact and dependable crimps for switchgear, substations, transformers, utility infrastructure, industrial plants, and commercial electrical systems. It is UL listed for 600 V applications and recommended for systems operating up to 35 kV.
