Overview
Aluminum Conductor Steel-Reinforced (ACSR) is a bare stranded conductor designed for overhead power transmission and distribution lines. It consists of a galvanized steel core surrounded by layers of aluminum strands. The aluminum provides electrical conductivity, while the steel core delivers tensile strength and mechanical support for longer spans. ACSR offers a practical balance of conductivity, strength, and installation efficiency. Typical applications include overhead transmission lines, distribution networks, utility infrastructure, rural electrification, and substation connections. Available configurations vary in conductor size, strand arrangement, aluminum-to-steel ratio, diameter, electrical resistance, and tensile strength. Selection should consider current capacity, span length, wind and ice loading, environmental conditions, and applicable standards. Contact Hongce Cable for product specifications and model selection.
