  • Product Description
  • Aluminum Conductor Steel Reinforced (ACSR) is a commonly used overhead conductor in power transmission and distribution systems. It combines the advantages of aluminum and steel, achieving an ideal balance between conductivity and mechanical strength.

    Core Structure and Composition

    Steel Core

    Located in the center of the conductor, usually composed of one or more galvanized steel wires twisted together.

    Function: Provides the main tensile strength, supports the weight of the conductor, ensures safe operation of the line, and galvanization provides corrosion protection.

    Outer Aluminum Layer

    Multiple aluminum wires are twisted together around the steel core to form the outer layer of the conductor.

    Function: Serves as the main conductor to transmit current.

    Key Characteristics and Advantages

    Excellent Mechanical Strength: The steel core provides extremely high tensile strength, enabling the conductor to withstand significant tension.

    Good Conductivity: The outer aluminum wires ensure sufficient current-carrying capacity.

    Cost-Effectiveness: Although aluminum's conductivity is not as good as copper's, its lower density and relatively lower price make it economical.

    Main Application Areas

    Transmission Lines: It is the main conductor for overhead transmission lines, used in 10KV, 35KV, 110KV, and other distribution networks.

    Long-Span Lines: Its high strength is particularly important for lines spanning rivers, valleys, and other long-distance segments.
