Shielded power cable for commercial and industrial applications, 5-46 kV

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. Where values are given in parentheses they are for information and comparison only.

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.
