Standard Specification for Concentric-Lay-Stranded Aluminum Conductors, Coated-Steel Reinforced (ACSR)

ABSTRACT
This specification covers concentric-lay-stranded aluminum conductors, coated-steel reinforced (ACSR), made from round aluminum 1350-H19 wires and round, coated steel core wire for use as overhead electrical conductors. ACSR covered by this specification has nine types of coated steel core wire which are designated by abbreviations as follows: ACSR/GA-ACSR, ACSR/GB-ACSR, ACSR/GC-ACSR, ACSR/MA-ACSR, ACSR/MB-ACSR, ACSR/MC-ACSR, ACSR/HS-ACSR, ACSR/MS-ACSR, and ACSR/AZ-ACSR. Before stranding, the aluminum wire and steel core wire shall meet the requirements prescribed. ACSR may be constructed using steel core wire with any one of nine types of protective coatings. The acceptable core wires are galvanized steel core wires, coating Classes A, B, or C ; high-strength galvanizes steel core wire; Zn-5Al-MM coated steel core wire; coating Classes A, B, or C ; aluminized steel core wire in accordance with the prescribed specifications. Tests for mechanical and electrical properties of zinc-coated, Zn-5Al-MM coated or aluminum coated steel wires shall be made before stranding. All aluminum wires composing the conductors shall be capable of meeting the bending property requirements after stranding.

Standard Specification for Concentric-Lay-Stranded Copper Conductors, Hard, Medium-Hard, or Soft

ABSTRACT
This specification covers standard requirements for bare-concentric-lay stranded conductors made from round copper wires, either uncoated or coated with tin, lead, or lead alloy for general use for electrical purposes. These conductors shall be constructed with a central core surrounded by one or more layers of helically laid wires. The conductors shall be classified as follows: Class AA, Class A, Class B, Class C, and Class D. Sizes, number of wires, and diameter of wires in the various classes of concentric-lay-stranded conductors shall conform to the prescribed requirements. Welds and brazes may be made in rods or in wires prior to final drawing. The completed conductor of varying classes shall conform to the minimum distance required between the joints. Diameters, areas, and mass of concentric-lay-stranded copper conductors shall conform to the prescribed requirements. Physical and electrical tests of conductors stranded of hard-drawn or medium-hard-drawn wires shall be conducted before but not after stranding. The approximate mass and electrical resistance may be determined using the required increments. The material shall also conform to the temperature corrections factor for conductor resistance.
SCOPE
1.1 This specification covers bare concentric-lay-stranded conductors made from round copper wires, either uncoated or coated with tin, lead, or lead alloy for general use for electrical purposes. These conductors shall be constructed with a central core surrounded by one or more layers of helically laid wires.  
Note 1: This specification also permits conductors for use as covered or insulated electrical conductors.
Note 2: Sealed conductors, that are intended to prevent longitudinal water propagation and are further covered/insulated, are also permitted within the guidelines of this specification.  
1.2 For the purposes of this specification, conductors are classified as follows (Explanatory Note 1 and Note 2):  
1.2.1 Class AA—For bare conductors usually used in overhead lines.  
1.2.2 Class A—For conductors to be covered with weather-resistant (weather-proof), slow-burning materials, and for bare conductors where greater flexibility than is afforded by Class AA is required.  
1.2.3 Class B—For conductors to be insulated with various materials such as rubber, paper, varnished cloth, and so forth, and for the conductors indicated under Class A where greater flexibility is required.  
1.2.4 Class C and Class D—For conductors where greater flexibility is required than is provided by Class B conductors.  
1.3 The SI values for density are regarded as the standard. For all other properties, the inch-pound values are to be regarded as standard and the SI units may be approximate.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Specification for 19 Wire Combination Unilay-Stranded Aluminum Conductors for Subsequent Insulation

ABSTRACT
This specification covers the standard requirements for bare combination unilay-stranded conductors made from round wires of aluminum 1350 and 8000 series of aluminum alloys, for insulated conductors to be used for electrical purposes. Aluminum 1350 wires in tempers -H19, -H16 or -H26, -H14 or -H24, and -H142 or -H242 and 8000 series aluminum alloy wires in tempers “0” and H1X or H2X are permitted. These conductors shall be constructed with a central core wire surrounded by two layers of helically laid wires, resulting in an outer diameter equal to the compressed-stranded equivalent conductors. Electric-butt welds, cold pressure welds, or electric-butt cold-upset welds may be made in the finished individual wires composing the conductor. Mechanical (tension) and electrical tests shall be performed on the wires composing the conductors that are annealed and not annealed after stranding. The mass and electrical resistance of a unit length of stranded conductor shall be determined as a function of the length of lay. The conductors shall meet the breaking strength, tensile strength, and bending strength requirements.
SCOPE
1.1 This specification covers bare combination unilay-stranded conductors made from round wires of aluminum 1350 and 8000 series of aluminum alloys, for insulated conductors for electrical purposes. Aluminum 1350 wires in tempers -H19 (extra hard), -H16 or -H26 (3/4 hard), -H14 or -H24 (1/2 hard), and -H142 or -H242 (1/2 hard) and 8000 series aluminum alloys wires in tempers “0” and H1X or H2X are permitted. These conductors shall be constructed with a central core wire surrounded by two layers of helically laid wires, resulting in an outer diameter equal to the compressed-stranded equivalent conductors.  
Note 1: For the purpose of this specification, combination unilay conductor is defined as follows: a central core wire surrounded by a layer of six helically laid wires of the same diameter as the core wire with a helically laid outer layer containing six smaller wires alternated between six wires of the same diameter as the wires in the layer underneath. Both layers have a common length and direction of lay (see Fig. 1).
FIG. 1 Cross Section of Conductor  
1.1.1 For the purpose of this specification, normal conductor classification (Class AA, A, B, C) is not applicable, as these conductors are intended for subsequent insulation. The descriptive term combination unilay-stranded shall be used in place of conductor classification (Note 2 and Note 3).
Note 2: Prior to 1975, aluminum 1350 was designated as EC aluminum.
Note 3: The aluminum and temper designations conform to ANSI Standard H35.1. Aluminum 1350 corresponds to Unified Numbering System A91350 in accordance with Practice E527. Unified Numbering System alloy designations for 8000 Series aluminum alloys in accordance with Practice E527 are listed in Table number 1 of Specification B800.  
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.  
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Specification for Cored, Annular, Concentric-Lay-Stranded Copper Conductors

ABSTRACT
This specification covers cored, annular, concentric-lay-stranded conductors made from round soft copper wires either uncoated or coated with tin for use as electrical conductors. The core may be of any materials and its size and surface firmness as a base for the overlaid wires shall be adequated to prevent forcing or dropping of any wire out of its layer position. No splice shall be made in the conductor as a whole, welds or brazes may be made in the finished individual wires. The materials shall conform to the required nominal conductor size, number of layers of wires, number, diameter, lay-up wires, approximate core diameter, and maximum conductor diameter. The mass per unit length and electrical resistance of a unit length of stranded conductor are a function of the length of lay and shall be calculated. The are of cross section of a conductor shall be considered to be the sum of the cross-sectional areas of its component wires at any section when measured perpendicularly to their individual axes.
SCOPE
1.1 This specification covers cored, annular, concentric-lay-stranded conductors made from round soft copper wires, either uncoated or coated with tin for use as electrical conductors (Explanatory Note 1 and Note 2).  
1.2 The constructions prescribed herein are suitable for bare conductors, or for conductors to be covered with weather-resistant (weather-proof) material, or for conductors to be insulated with rubber, varnished cloth, or impregnated paper, except types such as “oil-filled” or “gas-filled” (Explanatory Note 3).  
1.3 Cored, annular conductor constructions not included in this specification shall be specifically agreed upon between the manufacturer and the purchaser when placing the order.  
1.4 These constructions are not recommended for use as electric furnace leads where great flexibility is required and special conductor designs are indicated in consideration of the particular service requirements.  
1.5 The SI values for density are regarded as the standard. For all other properties the inch-pound values are to be regarded as standard and the SI units may be approximate.  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
