Overview

The ABB WR889 is an aluminum wide-range H-type compression connector designed for reliable, high-strength connections between ACSR (Aluminum Conductor Steel Reinforced) conductors. This connector supports a main conductor range of 477 kcmil (18/1) to 366 kcmil (500-336 strands) and a tap conductor range of 477 kcmil (18/1) to 336 kcmil (500-336 strands), making it suitable for medium to heavy-duty distribution and transmission applications. Constructed from high-conductivity aluminum, the WR889 ensures low electrical resistance and long-term corrosion resistance in outdoor and industrial environments. The H-type design provides a secure mechanical grip and electrical continuity, reducing the risk of loosening or arcing under load. The compression connection method ensures a permanent, vibration-resistant joint that meets or exceeds utility and industrial standards for conductor splicing. This connector is engineered for use in overhead power lines, substations, and industrial switchgear where ACSR conductors are standard. The 3-inch die specification aligns with common compression tooling, ensuring compatibility with standard hydraulic presses and manual crimping tools. The WR889 is part of ABB’s Installation Products line, a trusted brand in electrical infrastructure solutions. Key applications include: - Utility power distribution networks - Industrial power systems - Renewable energy installations (wind/solar farms) - Substation and switchgear interconnections The WR889 is a cost-effective, durable solution for professionals requiring a dependable compression connector with broad conductor compatibility. Always verify conductor compatibility and use the correct die size before installation.
