CSA C49.2-10:2018 pdf download.Compact round aluminum conductors steel reinforced (ACSR)
1.1 CSA C49.2-10 covers the electrical and mechanical characteristics of
a) round 1350-H19 hard-drawn aluminum wires (A1) before compacting;
b) round zinc-coated hard-drawn steel core wires (S1A); and
c) bare compact round concentric-lay-stranded aluminum conductors steel reinforced, constructed from the wires specified in Items (a) and (b) and intended for use in overhead lines.
1.2 In CSA Standards,“shall" is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; "should" is used to express a recommendation or that which is advised but not required;“may" is used to express an option or that which is permissible within the limits of the standard; and "can”is used to express possbility or capability. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. Notes to tables and figures are considered part of the table or figure and may be written as requirements. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
3 Definitions
In addition to the definitions in CAN/CSA-C61089, the following definitions shall apply in this Standard:
Compact round ACSR一a concentric-lay-stranded conductor consisting of a central single-wire steel core surrounded by one or two layers of helically laid round aluminum wires and compacted into an overall final round shape by drawing, roling, or other means.
Equivalent diameter一the diameter of a round wire that has the same cross-sectional area as a given formed wire of the same material.
4.3.1 Material
The completed conductor shall be made of a zinc-coated steel wire and aluminum wires having, after stranding, the mechanical and dimensional properties specified in this Standard.
4.3.2 Designation system
The conductor shall be designated in accordance with Clause 4 of IEC 62219, except that the code number that indicates the equivalent conductive section of A1F shall be expressed with at least two significant digits.
Note: The following are three examples of conductor designations:
a) 8.4/1.4-A1F/S1A-37: a conductor made of A1F formed aluminum wires and S1A regular-strength steel. The area of A1F aluminum is 8.4 mm2, and the area of S1A steel is 1.4 mm2. The nominal diameter of the conductor is (37x 0.1) mm.
b) 13/2.2-A1F/S1A-46: a conductor made of A1F formed aluminum wires and S1A regular-strength steel. The area of A1F aluminum is 13 mm2, and the area of S1A steel is 2.2 mm2. The nominal diameter of the conductor is (46x 0.1) mm.
c) 107/18-A1F/S1A-131: a conductor made of A1F formed aluminum wires and S1A regular-strength steel. The area of A1F aluminum is 107 mm2, and the area of S1A steel is 18 mm2. The nominal diameter of the conductor is (131 x 0.1) mm.CSA C49.2-10 pdf download.
