| 적용범위 | Preface This is the second edition of CSA C68.5, Primary shielded and concentric neutral cable for distribution utilities. It supersedes the first edition published in 2007. The first edition of CSA C68.5 adapted the requirements of the following documents: a) ANSI/ICEA S-94-649; b) ANSI/ICEA S-97-682; c) CEA Purchasing Specification WCWG-01 (95), XLPE Primary Cable up to #4/0 AWG; and d) CEA Purchasing Specification WCWG-02 (95), XLPE Primary Feeder Cable. The main revisions incorporated in the second edition of CSA C68.5 include: - The default diameter over insulation is now in accordance with ANSI/ICEA S-94-949 and S-97-682 (See Annex C). Diameters consistent with AEIC CS8 remain as a purchaser- specified option (see Annex B). - Crosslinked polyethylene (XLPE) and High-density polyethylene HDPE) are included as jacket materials - Marking requirements for cable reels are streamlined. - The cold bend test on finished cable as a production test is limited to No. 4/0 and smaller cable with extruded to fill jackets. The 3 m minimum sample length for the cold bend test is eliminated and the time to perform the bend is increased from 15 s to 1 min. - CV extrusion qualification is now included in production tests and removed from qualification test. - Deformation, weather resistance, and environmental stress cracking tests for jackets have been revised. - Preferred cable constructions to be used for cold impact and cold bend qualification tests on finished cable are specified. - The heat shock test has been moved from production tests to qualification tests. - Insulation shield thickness for cables other than concentric neutral is revised. - A new table that specifies jacket thickness and test voltages for lead sheath cables is included. This Standard is arranged to allow for selection of the individual components, such as conductors, insulation type and thickness, metallic shield or concentric neutral and jackets, that are required for specific installation and service conditions. Clauses 4 to 9 specify the materials, material characteristics, dimensions, and tests applicable to the major components of cables and if applicable, to the design concept. This Standard is considered suitable for use for conformity assessment within the stated scope of the Standard. Scope 1.1 The requirements of this Standard apply to materials, constructions, and testing of tree-retardant crosslinked 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. |
