CSA C22.2 NO. 96.1:16 (R2021)

Preface This is the fourth edition of CSA C22.2 No. 96.1, Mine power feeder cables , one of a series of Standards issued by CSA Group under the Canadian Electrical Code, Part II. It supersedes the previous editions, published in 2013, 2009, and 2004. In this edition, the testing procedures have been changed as a result of CSA C22.2 No. 03 being replaced by CSA C22.2 No. 2556. Ampacity values in Annex D have also been changed to align with the international industry requirements. This Standard is considered suitable for use for conformity assessment within the stated scope of the Standard. This Standard was prepared by the Subcommittee on Portable and Mine Power Cables, under the jurisdiction of the Technical Committee on Wiring Products and the Strategic Steering Committee on Requirements for Electrical Safety, and has been formally approved by the Technical Committee. 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. Scope 1.1 This Standard specifies construction and testing requirements for unarmoured mine power feeder cables normally used for power distribution in stationary or semi-stationary applications covered by CSA M421 and the Canadian Electrical Code, Part I. 1.2 This Standard covers cables with voltage levels of 5, 8, 15, 25, and 35 kV, rated at 100% and 133% insulation levels. 1.3 The cable constructions covered by this Standard are suitable for use at a maximum conductor temperature of 90 °C under normal operating conditions a) in wet or dry locations; b) outdoors; c) in underground mines; or d) in rugged environments. 1.4 This Standard does not specify all types, sizes, or temperature and voltage ratings of mine power feeder cables that can be required for particular applications. 1.5 In this Standard, \"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.
