Overview

ABB Installation Products 776LR-J5270-S is a 900 amp, 35 kilovolt deadbreak elbow connector engineered for medium-voltage cable systems. This 600 Series unit features a built-in test point for safe voltage verification without system de-energization, enabling efficient maintenance and troubleshooting in switchgear, transformers, and pad-mounted gear. The cold-shrinkable jacket seal provides a moisture-resistant, fully insulated interface when installed on cables with insulation diameters between 0.980 and 1.180 inches. The bi-metal compression lug accommodates compressed stranded 4/0 AWG, compacted solid 250 kcmil, or 125 mm² compact conductors, ensuring compatibility with a broad range of cable constructions. Supplied with an insulated plug, protective cap, compression stud, and cable adapter, this elbow delivers a complete termination solution for 35 kV class systems. Typical applications include utility substations, industrial power distribution, renewable energy interconnections, and commercial facilities requiring reliable, field-installable deadbreak terminations. The unit’s deadbreak design allows connection and disconnection under load, reducing downtime during system modifications or repairs. Cold-shrink technology eliminates heat-shrink processes, simplifying installation while maintaining consistent dielectric integrity across temperature cycles. ABB’s 600 Series elbows are designed for compatibility with industry-standard 600A class equipment, providing a dependable interface for medium-voltage cable accessories.
