This specification covers shaped wire compact concentric-lay-stranded aluminum conductor, steel-reinforced (ACSR/TW) and its component wires for use as overhead electrical conductors. Requirements for (1) wire stranding (2) tensile strength and elongation, (3) joints such as electric-butt welds, electric-butt cold-upset welds, or cold-pressure welds, and (4) lay length, diameter, direction, and factor are detailed. The construction requirements include: nominal aluminum cross sectional area, conductor type, nominal number of aluminum wires, number of layers, number and diameter of the steel core wire, mass per unit length, rated strength, and outside diameter of the shaped wire compact. The methods of determining mass per unit length, cross-section, and electrical resistance of the stranded conductor are given. Mechanical and electrical tests shall be performed before stranding.
Область применения1.1 This specification covers shaped wire compact concentric-lay-stranded aluminum conductor, steel-reinforced (ACSR/TW) and its component wires for use as overhead electrical conductors (Explanatory Note 1 and Note 2).
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
Note 1—ACSR/TW is designed to increase the aluminum area for a given diameter of conductor by the use of trapezoidally shaped wires (TW). The conductors consist of a central core of round steel wire(s) surrounded by two or more layers of trapezoidal aluminum 1350-H19 wires. Different strandings of the same size of conductor are identified by type, which is the approximate ratio of steel area to aluminum area expressed in percent (Table 1, Table 2 and Table 3). For the purpose of this specification, the sizes listed in Table 1 and Table 2 are tabulated on the basis of the finished conductor having an area or outside diameter equal to that of specific sizes of standard ACSR so as to facilitate conductor selection.TABLE 1 Construction Requirements for Shaped Wire Compact Concentric-Lay-Stranded Aluminum Conductors, Coated Steel Reinforced Size to Have Area Equal to ACSR, Class AAACSR/TW Conductor

A Code words shown in this column are obtained from “Publication 50, Code Words for Overhead Aluminum Electrical Conductors,” by the Aluminum Association. They are provided for information only.B Mass per unit length is based on Class A zinc-coated steel. To convert to kg/km, multiply the lb/1000 ft value x 1.4887.C Rated strength was calculated in accordance with 9.1 using steel stresses at 1 % for Class A coating in accordance with Specification B498/B498M (1 kip = 1000 lbf = 4.445 kN).D To convert the diameter (inches) to mm, multiply the inch value x 25.4.E To convert from kcmil to mm2 area, multiply the kcmil value x 5.067 x 10-4.TABLE 3 Construction Requirements for Shaped Wire Compact Concentric-Lay Stranded Aluminum Conductors Coated, Steel ReinforcedACSR/TW Conductor Size
