CSA C49.2-10 pdf free download.Compact round aluminum conductors steel reinforced ( ACSR ).
3 Definitions
In addition to the definitions in CAN/CSA-C61 089. the toflowng definitions shall apply In this Standard:
Compact round ACSR — a concentnc-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. rolbng, or other means.
(qulvalent 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 13S0-H19 hard-drawn aluminum wire (Al)
Before stranding and compacting, round 1 350-H19 hard-drawn aluminum wire (Al) shall comply with
CAN/CSA-C60889
4.2 Round zinc-coated steel core wire (SIA)
Round zinc-coated hard-drawn steel core wire (S1A) shall comply with CAN/CSA-C60888.
4.3 Completed conductors
4.3.1 MaterIal
The completed conductor shal be made of a zinc-coated steel wire and aluminum wires baying, after stranding, the mechanical and dimensional properties specified in this Standard.
4.3.2 flesignation 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 Al F shall be expressed with at least two s.gnlfkant digits.
