Standard Specification for Shaped Wire Compact Concentric-Lay-Stranded Aluminum Conductors, Coated-Steel Supported (ACSS/TW)
|Publication Date:||1 January 1995|
|ICS Code (Wires):||29.060.10|
1.1 This specification covers shaped wire compact concentric-lay-stran
NOTE 1--In this specification only shaped wire compact concentric-lay-stran
NOTE 2--For definitions of terms relating to conductors, refer to Definitions B 354.
1.2 The values stated in inch-pound units are to be regarded as the standard with the exception of temperature and resistivity. The SI equivalents given in parentheses may be approximate.
NOTE 3--ACSS/TW is designed to increase the aluminum area for a given diameter of conductor by the use of trapezoidal shaped wires (TW). The conductors consist of a central core of round steel wire(s) surrounded by two or more layers of trapezoidal aluminum 1350-0 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 (see 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 specified sizes of standard ACSR, ACSS, and ACSR/TW so as to facilitate conductor selection.
NOTE 4--The aluminum and temper designations conform to ANSI Standard H 35.1. Aluminum 1350 corresponds to Unified Number System (UNS) A91350 in accordance with Practice E 527.
