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<\/sup> \/ 4<\/sub> hard), -H14 or -H24 ( 1<\/sup> \/ 2<\/sub> hard), and -H142 or -H242 ( 1<\/sup> \/ 2<\/sub> 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.<\/p>\n

\n Note 1<\/span> 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<\/span> ).<\/span><\/p>\n

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 ).<\/p>\n

\n Note 2<\/span> Prior to 1975, aluminum 1350 was designated as EC aluminum.<\/span>\n <\/div>\n
\n Note 3<\/span> 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 .<\/span>\n <\/div>\n<\/p><\/div>\n<\/p><\/div>\n

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.<\/p>\n<\/p><\/div>\n
