Overview

The ABB WR799 is a high-performance aluminum H-type compression connector engineered for overhead power distribution systems. Designed for utility and electrical contractors, this connector delivers reliable, low-resistance electrical connections between main and tap conductors in distribution networks. The WR799 accommodates a wide range of conductor sizes, supporting main conductors from 477 kcmil 18/1 to 266 kcmil ACSR (Aluminum Conductor Steel Reinforced) and 500-250 kcmil stranded aluminum. For tap connections, it supports 4-6 kcmil ACSR, 3-6 kcmil stranded aluminum, and 2-6 kcmil solid aluminum conductors. The H-type design ensures a robust mechanical connection with minimal power loss, critical for maintaining system integrity in overhead line applications. The WR799 uses a specific die size (N. 2 inch) for proper compression, ensuring a secure interface. Compatible with hydraulic tools (12-ton or greater), the WR799 requires three indents for proper installation. This connector is ideal for utility projects, substation upgrades, and distribution network configurations requiring dependable aluminum conductor splicing and tapping. Manufactured by ABB - Installation Products (SKU: WR799), it is a precise solution for overhead power distribution systems where reliability and performance are paramount.
