3 Definitions In addition to the definitions in CAN/CSA-C61 089, the following definitions shall apply in this Standard: Compact round ACSR — 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, rolling, or other means. Equivalent diameter — the diameter of a round wire that has the same cross-sectional area as a given formed wire of the same material. 4 Construction 4.1 Round 1350-H19 hard-drawn aluminum wire (A1) Before stranding and compacting, round 1 350-H1 9 hard-drawn aluminum wire (A1 ) shall comply with CAN/CSA-C60889. 4.2 Round zinc-coated steel core wire (S1A) Round zinc-coated hard-drawn steel core wire (S1 A) shall comply with CAN/CSA-C60888. 4.3 Completed conductors 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 6221 9, except that the code number that indicates the equivalent conductive section of A1 F 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 mm 2 , and the area of S1A steel is 1 .4 mm 2 . The nominal diameter of the conductor is (37 × 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 1 3 mm 2 , and the area of S1A steel is 2.2 mm 2 . The nominal diameter of the conductor is (46 × 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 1 07 mm 2 , and the area of S1A steel is 1 8 mm 2 .
4.3.3 Standard sizes The diameter of the zinc-coated steel wire and the nominal cross-sectional area of aluminum and steel for the standard sizes of completed conductors shall comply with Table 1 . 4.3.4 Surface The surface of the completed conductor shall be free from all imperfections not consistent with good manufacturing practice. 4.3.5 Stranding 4.3.5.1 The aluminum wires of compact round ACSR shall be concentrically stranded.
4.3.5.2 The aluminum layers of compact round ACSR having two layers shall be stranded in opposite directions. The direction of lay of the outer layer shall be right-hand. 4.3.5.3 The lay factors for aluminum wire layers shall be in accordance with Clause 5.4.5 of CAN/CSA-C61 089. 4.3.6 Joints Joints shall comply with Clause 5.5 of CAN/CSA-C61 089. 5 Linear mass and tensile strength of completed conductors 5.1 Linear mass The linear mass of the completed conductor shall be determined in accordance with Clause 6.6.3 of CAN/CSA-C61 089 and shall not vary by more than ±2% from the appropriate nominal value specified in Table 1 . To verify compliance with Table 1 , the mass per unit length and resistivity of the stranded conductor may be determined from stranding increments calculated based on the actual lay of the conductor. 5.2 Tensile strength 5.2.1 The rated tensile strength of the completed conductor, as specified in Table 1 , shall be calculated in accordance with Clause 5.7 of CAN/CSA-C61 089.CSA C49.2-10 pdf download.
