Full Description

Preface:

This is the third edition of CSA C68.5, Primary shielded and concentric neutral cable for distribution utilities. It supersedes the previous editions published in 2013 and 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 third edition of CSA C68.5 include the following: Clarification on the four classifications of ethylene propylene rubber insulation and applicable requirements; Removal of thermally strippable insulation shield; Addition of "WBS" for blocked strand or "WBC" blocked cable for constructions incorporating water- blocking component; Removal of the word "optional" for Thermomechanical qualification test to clarify that this test is mandatory on jacketed cables. 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 a specific installation and service conditions. Clauses 4to 9specify the materials, material characteristics, dimensions, and tests applicable to the major components of cables and, if applicable, to the design concept.

Funding in support of the consensus process of this Standard was provided by the following funders, whose assistance is acknowledged with thanks: Canadian Electricity Association (CEA), S "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.
