Overview

ABB Installation Products CPL 556 N bi-metallic lugs are engineered for terminating ACSR 477 aluminum stranded conductors with a cross-sectional area of 396.500–556.5 kcmil. Designed for 1/2" bolt connections, these lugs ensure reliable electrical conductivity and mechanical strength in overhead and underground distribution systems. The bi-metallic construction combines aluminum and copper alloys to minimize galvanic corrosion while maintaining low contact resistance. This design is critical for applications where aluminum conductors interface with copper or aluminum busbars, reducing the risk of overheating and failure. These lugs are rated for use in utility, industrial, and commercial electrical systems where high-current terminations are required. The two-hole design provides secure mounting and reduces vibration-induced loosening, a common issue in high-vibration environments such as substations or industrial machinery. Compatible with standard 1/2" bolts, the CPL 556 N lugs are manufactured to meet industry standards for mechanical and electrical performance. They are suitable for use with ACSR conductors in power distribution, renewable energy installations, and heavy industrial applications where conductor sizes fall within the specified range.
