Overview

The ABB WR739 is an H-Type compression connector designed for electrical power distribution applications. Manufactured by ABB Installation Products, this connector facilitates secure and reliable splices between conductors. It is constructed from aluminum, a common material for overhead line connectors due to its conductivity and corrosion resistance. This specific model, WR739, is engineered for a wide range of conductor sizes. The main conductor capacity accommodates 397 kcmil 18/1-266 ACSR (Aluminum Conductor Steel Reinforced) and 400-250 kcmil stranded conductors. The tap conductor capacity is designed for 4/0-1/0 ACSR, 4/0-2/0 stranded conductors, and 4/0 solid conductors. The connector utilizes a specific die size, indicated as 'N. 2 inch', which is crucial for achieving the correct compression force and ensuring electrical integrity. The 'N' designation likely refers to a specific die profile or series within ABB's tooling system, and the '2 inch' refers to the length of the compression stroke or die length, critical for proper installation with compatible crimping tools.
