CSA C49.8-09 pdf free download.Bare overhead aluminum conductors for distribution applications.
1.1
This CSA C49.8 specifies requirements for concentric-lay aluminum stranded conductors, with or without
a central core of reinforcing steel strand. These conductors are intended for overhead installation on
single-phase or three-phase electrical distribution systems.
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 possibility 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.
1.3
The values given in SI units are the units of record for the purposes of this Standard. The values given in parentheses are for information and comparison only.

3 Material and construction
3.1
Conductors listed in Table 1 shall meet the requirements of CAN/CSA-C61 089.
3.2
The steel core wire used for composite conductors listed in Table 1 shall meet or exceed the requirements for Si A wires specified in CAN/CSA-C60888, except for 3/0 AWG AACSR, which shall meet or exceed the requirements (or S3A wires.
4 Tests
4.1 General
Conductors shall be tested in accordance with CAN/CSA-C61 089.
4.2 Recoil and torque type test
The following test shall be performed for each strander set-up on A2 conductor 7-wire designs specified in
Table 1:
(a) At least 15 m of completed stranded conductor shall be pulled oft the strander, at the capstan, without allowing any rotation of the free conductor end. When the conductor is cut, the strands shall not unravel, and the conductor end shall not rotate more than two turns when released.
(b) The same conductor shall be laid out on a straight line. When the two ends are released, at least 60% of the length in the centre of the conductor shall be straight and shall not deviate from the line by more than 30 cm in either direction. The conductor shall lie flat with no veftical displacement.
5 Packaging and package marking
5.1 Packaging
Completed conductors as specified in Table 1 shall be packaged on NEMA WC 26/EEMAC 201 Class Ill returnable wood reels or NEMA WC 26/EEMAC 201 Class I returnable steel fluted reels. Recommended metric shipping lengths are listed in Table Al.
The actual length on any reel shall fall within a tolerance of 5% of the shipping length specified for lengths of 1000 m or less, and within a tolerance of 3% for lengths greater than 1000 m.
A length of conductor shorter than that recommended in Table A.i may be supplied on a reel.
5.2 Package marking
Package marking shall be provided on one or more tags located on the outside of the reel flange. Where multiple tags are used, they shall be adjacent to each other.CSA C49.8-09 pdf free download.
