Standard Specification for Concentric-Lay-Stranded Aluminum 1350 Conductors
|Publication Date:||1 October 2016|
This specification covers aluminum 1350-H19 (extra hard), 1350-H16 or -H26 (3⁄4 hard), 1350-H14 or -H24 (1⁄2 hard), and 1350-H142 or -H242 (1⁄2 hard), bare concentric-laystrand
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.
For density, resistivity and temperature, the values stated in SI units are to be regarded as standard.
NOTE 1-Prior to 1975, aluminum 1350 was designated as EC aluminum.
NOTE 2-The aluminum and temper designations conform to ANSI Standard H35.1/H35.1M. Aluminum 1350 corresponds to Unified Numbering System A91350 in accordance with Practice E527.
NOTE 3-Sealed conductors that are intended to prevent longitudinal water propagation and are further covered/insulated are also permitted within the guidelines of this specification.
