Overview

The ABB WR719 is a high-performance aluminum wide range H-type compression connector engineered for secure, high-conductivity parallel conductor joints in overhead power distribution systems. This utility-grade connector accommodates a main conductor range of 397 18/1-266 ACSR with stranding options of 400-250, and a tap conductor range of 2/0-3 ACSR with stranding options of 2/0-2 or 3/0-1. The WR719 uses die size N (2 inch) for compression, ensuring compatibility with standard hydraulic or mechanical compression tools rated for 12-ton or greater force. H-type connectors are critical in applications requiring reliable parallel conductor connections, such as distribution transformers, riser poles, and junction points in overhead lines. The aluminum construction provides corrosion resistance and electrical conductivity comparable to copper in many environments, reducing material costs without sacrificing performance. The wide range design minimizes inventory needs by covering multiple conductor sizes in a single part number, supporting both standard and compact conductor configurations. Installation requires a hydraulic compression tool with three indents (e.g., Blackburn JB12A, JB12B, 12A, or Y-35 tools). The connector’s H-type design allows for easy alignment and secure clamping of both main and tap conductors, reducing installation time and improving joint integrity. This connector meets utility-grade standards for mechanical strength and electrical continuity, ensuring long-term service in exposed outdoor conditions. The WR719 is designed for use with ACSR conductors and supports a 3% reduction in compressed conductor diameter for enhanced flexibility in field applications.
