Overview

The ABB WR715 is a wide-range aluminum H-type compression tap connector engineered for reliable overhead distribution systems. This connector supports a main conductor range of 397-266 kcmil ACSR (400-250 stranding) and a tap conductor range of 2/0-6 AWG ACSR (2/0-6 stranding), 2/0-6 AWG stranded, or 3/0-6 AWG solid. Designed for utility-grade applications, the WR715 ensures durable, low-resistance terminations in environments exposed to weather, vibration, and thermal cycling. Key specifications include a die size N (2 inch) for compression installation, compatible with standard hydraulic tools (12-ton or greater). The connector features two indents when installed with tools like the Blackburn JB12A, JB12B, 12A, or Y-35. Its aluminum construction provides corrosion resistance and compatibility with ACSR conductors without additional plating or coatings. Typical applications include utility pole connections, transformer taps, and branch circuit splicing where aluminum conductors require secure mechanical and electrical joints. The wide-range design reduces inventory needs by covering multiple conductor sizes in a single connector type, optimizing stock management for utilities and contractors. Installation requires standard compression tools and follows manufacturer guidelines for proper indentation and tool alignment. The WR715 is part of ABB’s Blackburn line of overhead connectors, known for reliability in outdoor and high-stress environments. Its compact design and compatibility with compact conductors (with a 3% diameter reduction tolerance) make it versatile for both standard and compressed conductor applications.
