ASTM B901-04

Standard Specification for Compressed Round Stranded Aluminum Conductors Using Single Input Wire Construction

ABSTRACT
This specification covers aluminum 1350-H19, 1350-H16 or -H26, 1350-H14 or -H24, 1350-H142 or -H242, and aluminum alloy 8XXX series for tempers "O" and H1X or H2X, bare stranded conductors composed of one or more roller shaped or die compressed layers of helically laid wires. The conductors are for general use for electrical purposes. The conductors described in this specification are intended for subsequent insulation or covering. The areas of cross section, the minimum number of wires, and diameters of the finished strand shall conform to the prescribed construction requirements. The rated strength of 1350-H19 conductors shall be taken as the percent of the sum of the strengths of the component wires, calculated using the nominal wire diameters and the specified minimum average tensile strength. The rated strength of 800 series conductors shall be taken as the percent of the sum of strengths of the component wires, calculated using nominal wire diameters and the specified minimum average tensile strength. The approximate mass and electrical resistance may be determined using the standard increments due to stranding. Mechanical and electrical tests shall be made for not annealed and annealed conductors after stranding. Temperature correction factors for conductor resistance shall be provided when dc resistance is measured at specified temperatures.
SCOPE
1.1 This specification covers aluminum 1350-H19 (extra hard), 1350-H16 or -H26 (3/4 hard), 1350-H14 or -H24 (1/2 hard), 1350-H142 or -H242 (1/2 hard), and aluminum alloy 8XXX series as listed in Specification B 800 for tempers "O" and H1X or H2X, bare stranded conductors composed of one or more roller shaped or die compressed layers of helically layed wires. The conductors are for general use for electrical purposes (Explanatory Notes 1 and 2).Note 1
For the purposes of this specification, single input wire (SIW) construction is defined as follows: a stranded conductor design methodology that varies the number of wires within a range of conductor sizes in order to permit that range of conductor sizes to be constructed from a single wire size.
1.2 The values stated in inch-pound or SI units are to be regarded separately as standard. The values in each system are not exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.
1.2.1 For density, resistivity, and temperature, the values stated in SI units are to be regarded as standard.Note 2
Prior to 1975, aluminum 1350 was designated as EC aluminum.Note 3
The aluminum and temper designations conform to ANSI H35.1. Aluminum 1350 corresponds to Unified Numbering System A91350 in accordance with Practice E 527. Aluminum alloys in the 8000 series correspond to Unified Numbering System A98XXX in accordance with Practice E 527.Note 4
This specification also permits conductors for use as covered or insulated electrical conductors.Note 5
Sealed conductors, which are intended to prevent longitudinal water propagation and are further covered/insulated, are also permitted within the guidelines of this specification.
