CSA C49.5:10 (R2019)
This is the second edition of CSA C49.5, Compact round aluminum stranded conductors (compact round ASC). It supersedes the first edition, published in 1978 under the title Compact Round Concentric-Lay Aluminum Stranded Conductors (Compact ASC).
This Standard covers the electrical and mechanical characteristics of
(a) round 1350 aluminum wires used before compacting in the construction of conductors; and
(b) bare compact round aluminum stranded conductors (compact round ASC) constructed from the wires specified in Item (a).
The following classifications apply to those conductors covered by this Standard:
(a) Class AA: for bare conductors used in overhead lines.
(b) Class A: for bare conductors where greater flexibility than is afforded by Class AA is required; or
for conductors to be covered with weather-resistant (weather-proof) materials or materials such as thermoplastics, thermosets, pagers, etc.
(c) Class B: for the conductors specified in Item (b) where greater flexibility than is afforded by Class A is required; or for conductors to be covered with materials such as thermoplastics, thermosets, paper, etc.
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.
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.
