This standard is issued under thefixed designation B524/B524M;the number immediately following the designation indicates the year of original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.
A superscript epsilon(´)indicates an editorial change since the last revision or reapproval.
1.Scope
1.1This specification covers concentric-lay-stranded con-ductors made from round aluminum1350-H19(extra hard) wires and round aluminum-alloy6201-T81(hard:solution heat treated,cold worked,and then artificially aged)core wires for use as overhead electrical conductors(Explanatory Note1).
N OTE1—The aluminum,alloy,and temper designations conform to ANSI H35.1/ANSI H35.1[M].Aluminum1350and Alloy6201corre-spond to unified numbering system A91350and A96201,respectively,in accordance with Practice E527.
1.2The 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.
1.2.1For density,resistivity and temperature,the values stated in SI units are to be regarded as standard.
1.3This standard does not purport to address all of the safety concerns,if any,associated with its use.It is the responsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.

5.Joints
5.1In conductors composed of seven wires,only cold-pressure welds and electric butt,cold-upset welds may be made in the six outer finished wires.No welds are permitted in the center core wire.In other conductors,cold-pressure welds,electric-butt,cold-upset welds,or electric-butt welds may be made in the finished wires.Such joints in the same wire or any other wire in the conductor shall be no
t closer than prescribed in Table 3.Following welding,electric-butt welds in 6201wires shall be annealed for a distance of at least 6in.(150mm)on each side of the weld (Explanatory Note 2).
6.Lay
6.1The preferred lay of a layer of wires is 13.5times the outside diameter of that layer,but the lay shall be not less than 10nor more than 16times this diameter.
6.2The direction of lay of the outer layer shall be right-hand unless specified otherwise by the purchaser.The direction of lay shall be reversed in successive layers.
7.Construction
7.1The number and diameter of wires and the areas of cross section of conductors shall conform to the requirements prescribed in Table 1or Table 2.
7.2Recommended standard strandings are as shown in Table 4.
8.Strength of Conductor
8.1The rated strength of completed conductors shall be taken as the aggregate strength of the aluminum 1350and the aluminum-alloy 6201components,calculated as follows.The strength contribution of the aluminum 1350wires shall be taken as the percentage indicated in Table 6,of the sum of the strengths of the aluminum 1350wires,calculated from their specified nominal wire diameter and the appropriate specified minimum average tensile strength given in Specification B230/B230M .The strength contribution of the aluminum-alloy 6201
wires shall be taken as that percentage,according to the number of layers of aluminum-alloy 6201wires,indicated in Table 6,of the sum of the strengths of the aluminum-alloy 6201wires,calculated from their specified nominal wire diameter and the minimum stress at 1%extension.This shall be considered to be 95%of the minimum average tensile strength specified for the wire diameter in Specification B398/B398M .
8.2Tests for determining the rated strength of the completed conductor are not required by this specification but may be made if agreed upon by the manufacturer and the purchaser at the time of placing an order.If tested,the breaking strength of the completed conductor shall be not less than the rated strength if failure occurs in the free length at least 1in.(25mm)beyond the end of either gripping device,or shall be not less than 95%of the rated strength if failure occurs inside,or within 1in.(25mm)
of the end of,either gripping device (Explanatory Note 3).
8.3Rated strength and breaking strength values shall be rounded to three significant figures,in the final value only,in accordance with the rounding method in Practice E29.8.4Rated strength of conductors is given in Table 2or Table 7.9.Density
9.1For the purpose of calculating mass,mass per unit length,cross sections,and so forth,the density of 1350-H19is 2705kg/m 3(0.0975lb/in.3)at 20°C and the density of 6201-T81is 2690kg/m 3(0.097lb/in.3)at 20°C.10.Mass Electrical Resistance
10.1The mass and electrical resistance of a unit length of stranded conductor are a function of the length of lay.The approximate mass per unit length and electrical resistance may be determined using the standard increments shown in Table 8.
