Preface
This is the first edition of CSA C68.5, Primary shielded and concentric neutral cable for distribution utilities. It supersedes the requirements for application by electric utilities found in CAN/CSA-C68.3-97, Shielded and Concentric Neutral Power Cable Rated 5-46 kV. CAN/CSA-C68.3-97 continues to apply to the industrial applications of shielded and concentric neutral cable; a new edition is in development.
1 Scope
1.1
The requirements of this Standard apply to materials, constructions, and testing of tree-retardant cross-linked polyethylene and ethylene propylene rubber-insulated single conductor or triplexed primary shielded and concentric neutral power cables rated 15 to 46 kV that are used for the transmission and distribution of electrical energy. The products covered by this Standard are suitable for direct burial or installation in ducts in both wet and dry locations and where cable will be exposed to sunlight.
1.2
This Standard specifies the requirements for shielded and concentric neutral cable intended primarily for operation by electric utilities.
Note: The operation of cables complying with this Standard by other than an electric utility can be subject to additional requirements by the electrical inspection authority having jurisdiction.
1.3
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.
1.4
The values given in SI (metric) units are the standard. The values given in parentheses are for information only.
