    Construction

    ● Conductor: Made from high-quality copper or aluminum, providing superior electrical conductivity and mechanical strength.
    ● Insulation:  Features materials like TR-XLPE (Tree Retardant Cross Linked Polyethylene) to ensure electrical safety and durability.
    Sheathing: Some cables include LLDPE (Low-Density Polyethylene) sheathing for added mechanical protection and enhanced safety, particularly in case of fire.
    Armoring: For certain industrial applications, cables may be equipped with steel wire armoring (SWA) or aluminum wire armoring (AWA) to offer additional mechanical protection.

    Standard

    ASTM B231

    1. Title: Standard Specification for Concentric-Lay-Stranded Aluminum 1350 Conductors.
    2. Scope: ASTM B231, issued by the American Society for Testing and Materials (ASTM), covers concentric-lay-stranded aluminum conductors made from 1350-H19 (extra hard), 1350-H16 or -H26 (3/4 hard), 1350-H14 or -H24 (1/2 hard), and 1350-H142 or -H242 (1/2 hard) aluminum alloys. These conductors feature a central round wire surrounded by one or more helically laid layers of wires and are intended for general electrical use.

    ASTM B609

    1. Title: Standard Specification for Aluminum 1350 Round Wire, Annealed and Intermediate Tempers, for Electrical Purposes.
    2. Scope: ASTM B609, published by the American Society for Testing and Materials (ASTM), specifies aluminum 1350 wires in various tempers, including 1350-O (annealed), 1350-H12 or -H22 (1/4 hard), 1350-H14 or -H24 (1/2 hard), 1350-H16 or -H26 (3/4 hard), and 1350-H142 or -H242 (1/2 hard). This standard covers wire suitable for stranding into conductors or as solid single conductors, either bare or insulated, for electrical applications.

    ASTM B8

    1. Title: Standard Specification for Concentric-Lay-Stranded Copper Conductors, Hard, Medium-Hard, or Soft.
    2. Scope: ASTM B8, issued by the American Society for Testing and Materials (ASTM), specifies bare concentric-lay-stranded copper conductors made from round copper wires. These conductors may be uncoated or coated with tin, lead, or a lead alloy and are designed for general electrical use. They consist of a central core surrounded by one or more layers of helically laid wires.

    ASTM B33

    1. Title: Standard Specification for Tinned Soft or Annealed Copper Wire for Electrical Purposes.
    2. Scope: ASTM B33, published by the American Society for Testing and Materials (ASTM), covers tinned, round, soft, or annealed copper wire used for electrical purposes. The standard specifies the requirements for the wire’s construction, ensuring it meets the necessary performance and safety criteria for electrical applications.

    ICEA S-94-649

    1. Title: Standard for Concentric Neutral Cables Rated 5 Through 46 kV.
    2. Scope: ICEA S-94-649, issued by the Insulated Cable Engineers Association (ICEA), defines the materials, construction, and testing requirements for concentric neutral cables insulated with crosslinked polyethylene, tree-retardant crosslinked polyethylene, or ethylene propylene rubber. These cables are rated from 5 to 46 kV and are used for the transmission and distribution of electrical energy.

    AEIC CS-8

    1. Title: Specification for Extruded Dielectric, Shielded Power Cables Rated 5 Through 46 kV.
    2. Scope: AEIC CS-8, published by the Association of Edison Illuminating Companies (AEIC), supplements ANSI/ICEA Standards S-94-649 and S-97-682. It covers specifications for extruded dielectric, shielded power cables rated 5 through 46 kV, used for the distribution of electric energy in utility systems.

    Rural Utility Standard RUS 1728.204

    1. Title: Electric Standards and Specifications for Materials and Construction.
    2. Scope: RUS 1728.204, developed by the Rural Utilities Service (RUS) of the USDA, specifies requirements for 15 and 25 kV single-phase, V-phase, and three-phase power cables used in underground distribution systems. The cables must be insulated with tree-retardant cross-linked polyethylene (TR-XLPE) or ethylene propylene rubber (EPR) and include concentrically wound copper neutral conductors covered by a nonconducting or semiconducting jacket.

    UL 1072

    1. Title: Standard for Medium-Voltage Power Cables.
    2. Scope: UL 1072, issued by Underwriters Laboratories (UL), specifies the requirements for shielded and non-shielded medium-voltage power cables, including both single-conductor and multiple-conductor types. The standard covers cables with one or more stranded copper or aluminum conductors, insulated with a solid, extruded dielectric. Cables with metal sheaths or interlocked armor must incorporate an effective grounding path.
