HTLS Conductor Products --- Aluminum Conductor Steel Supported-ACSS and ACSS/TW

Definition & Composition

ACSS conductor cable is composed of a concentric stranded composite conductor. It consists of a galvanized steel strand core and one or more layers of annealed cargo soft 1350-0 aluminum. The steel core is A-grade galvanized steel, which carries most or all of the mechanical load of the conductor due to the annealed or softened aluminum, which can provide high strength depending on the requirements.

Standard

Q320623 AP 32, IEC 61089, IEC 62219, ASTM B609, ASTM B851, ASTM B856, ASTM B857

Technical Characteristics

ACSS is commonly used in overhead transmission and distribution lines. It can operate continuously at temperatures up to 250°C without loss of its strength. Under electrical loads, ACSS has a lower sag strength than comparable ACSR. It can be self-damping if pre-stretched during installation. Its final sag is not subjected to the long-term creep condition of aluminum. These advantages make ACSS particularly useful in heavy conductivity applications where an increased current is required.
