This is the first edition of CSA C68.9, Covered overhead distribution line wire. This Standard is based on Canadian Electricity Association (CEA) WCWG-06 (95), Covered Overhead Lines Wire (used with permission from CEA).
This Standard specifies requirements for covered overhead distribution line wire. These conductors are intended for overhead installation as single conductors on single-phase or three-phase electrical distribution systems.
This Standard does not cover conductors intended for field-spun applications.
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.
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.
