Preface<\/strong><\/p>\n

<\/p>\n

This is the first edition of CSA C68.7, Underground secondary and service-entrance cable for electrical distribution utilities.<\/em><\/p>\n

<\/p>\n

This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.<\/p>\n

<\/p>\n

Scope<\/strong><\/p>\n

<\/p>\n

1.1<\/p>\n

This Standard specifies requirements for 600 V copper and aluminum conductor secondary and service-entrance cables intended primarily for operation by electrical utilities. These cables are intended for underground installation<\/p>\n

<\/p>\n

(a) by direct burial; or<\/p>\n

<\/p>\n

(b) in conduit systems.<\/p>\n

<\/p>\n

This Standard also applies to multiple-conductor cable assemblies.<\/p>\n

<\/p>\n

Notes:<\/p>\n

<\/p>\n

(1) The cables covered by this Standard are exposed to sunlight on terminal poles and during storage.<\/p>\n

<\/p>\n

(2) The operation of cables complying with this Standard by other than an electrical utility can be subject to additional requirements by an authority having jurisdiction.<\/p>\n

<\/p>\n

1.2<\/p>\n

This Standard applies to cables with<\/p>\n

<\/p>\n

(a) a maximum allowable conductor temperature of 75 \u00b0C or 90 \u00b0C; and<\/p>\n

<\/p>\n

(b) cold impact and cold bend ratings of -40 \u00b0C.<\/p>\n

<\/p>\n

1.3<\/p>\n

Cables rated at 75 \u00b0C are suitable for voltage regulation limited applications where ampacity considerations are not applicable. Cables rated at 90 \u00b0C are suitable for ampacity limited applications.<\/p>\n

<\/p>\n

1.4<\/p>\n

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.<\/p>\n

<\/p>\n

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.<\/p>\n

<\/p>\n

Notes to tables and figures are considered part of the table or figure and may be written as requirements.<\/p>\n

<\/p>\n

Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.<\/p>\n
