C68.10-14 - Shielded power cable for commercial and industrial applications, 5-46 kV
Preface
This is the second edition of CSA C68.10, Shielded power cable for commercial and industrial applications, 5-46 kV. It supersedes the previous edition published in 2008. The first edition of this Standard replaced the requirements for shielded power cable in commercial and industrial installations specified in CAN/CSA-C68.3, Shielded and concentric neutral power cables rated 5-46 kV. A related standard in the CSA C68 series, CSA C68.5, specifies the requirements for application of shielded and concentric neutral cables used by electric utilities. This Standard was originally adapted from NEMA WC 74/ICEA S-93-639. CSA Group gratefully acknowledges the co-operation of the Insulated Cable Engineers Association (ICEA) and the contribution of its members. The main revisions incorporated in this edition include the following: a) updated reference publications (Clause 2); b) new definitions (e.g., thermoset, thermoplastic, and water blocking component, Clause 3); c) clarification of bonding conductors in multiple-conductor cable (Clause 11.3.3); d) revised sample preparation criteria for air oven and oil immersion testing (Clauses 13.4.9.2 and 13.4.9.3); e) revised insulation resistance test (Clause 14.2.2); f) updated wording for the longitudinal water penetration test in Clause 14.6.2; g) increased insulation thickness and ac test voltage for the 133% insulation level of cable rated less than or equal to 5 kV (Tables 8 and 9); and h) general updating of terminology to be consistent with updates made to CSA C68.5. This Standard was prepared by the Subcommittee on Shielded and Concentric Neutral Power Cables Rated 5-46 kV, under the jurisdiction of the Technical Committee on Insulated Power Cable and the Strategic Steering Committee on Power Engineering and Electromagnetic Compatibility.Scope
1.1 This Standard applies to the materials, construction, and testing of one- to four-conductor cross-linked polyethylene and ethylene propylene rubber-insulated shielded power cables, rated 5-46 kV, that are used for the distribution of electrical energy under normal conditions of installation and service in indoor, outdoor, aerial, underground, or underwater locations. 1.2 This Standard specifies requirements for conductors, insulation, and protective coverings as well as for the construction and dimensions of most standard types of shielded cable. 1.3 This Standard does not preclude the use of optional components such as polymeric layers for additional mechanical protection, moisture-impervious laminated sheath, individually covered steel wire armour, or optical fibres, provided that the components meet the performance requirements of this Standard. Test procedures for these optional components are not included in this Standard. 1.4 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. 1.5 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; and 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.CONTENT PROVIDER
