Overview

The ABB AC556 is a full-tension distribution compression splice engineered for reliable connections in aluminum conductor applications. Constructed from durable aluminum, this splice offers robust performance for critical electrical infrastructure. Its 13-1/2 inch length is specifically designed to accommodate a comprehensive range of aluminum conductor sizes, including 556 kcmil with 19 strands and 37 strands. This specification ensures a secure and efficient termination for medium to large gauge aluminum conductors commonly found in distribution networks. For installation, the AC556 requires specific hydraulic dies to achieve a proper compression. Compatible dies include the B76AH and the 318, with a die opening of 1 5/16 inches. Utilizing the correct hydraulic tooling is paramount for creating a permanent, low-resistance connection that meets the stringent requirements of full-tension applications. The full-tension rating signifies that this splice is designed to withstand the mechanical stresses and electrical loads inherent in overhead distribution lines, ensuring long-term operational integrity. This ABB Installation Products component (SKU: AC556) is a key element for utility companies and electrical contractors performing line construction and maintenance. Its aluminum construction provides excellent conductivity and corrosion resistance, essential for outdoor environments. The AC series designation highlights its role within ABB's comprehensive range of connection solutions for electrical distribution systems. When specifying components for your next project, the AC556 offers a direct, spec-driven solution for your aluminum conductor splicing needs.
