Defines requirements and test methods for the construction, dimensions and mechanical and electrical properties of armoured cables with thermosetting insulation for rated voltages from 3.8/6.6 (7.2) kV up to 19/33 (36) kV inclusive, designed for a maximum continuous conductor operating temperature of 90 degrees C and for a maximum short circuit conductor temperature of 250 degrees C, for use in fixed installations such as networks or industrial installations.

This British Standard specifies requirements and test methods for the construction, dimensions and mechanical and electrical properties of armoured cables with thermosetting insulation for rated voltages from 3.8/6.6 (7.2) kV up to 19/33 (36) kV inclusive, designed for a maximum continuous conductor operating temperature of 90 °C and for a maximum short circuit conductor temperature of 250 °C, for use in fixed installations such as networks or industrial installations.

This British Standard specifies single-core and three-core cables for voltages in the range 3.8/6.6 (7.2) kV up to 19/33 (36) kV, with:

1. a stranded copper, stranded aluminium or solid aluminium conductor or conductors;
2. cross-linked polyethylene or cross-linked ethylene propylene rubber insulation;
3. a metallic screening layer of copper wire or copper tape and/or a metallic armour of aluminium or galvanized steel wire;
4. a polyvinyl chloride compound (PVC) or polyethylene (PE) oversheath.

NOTE Guidance on the selection of cables is given in Annex A. Information to be supplied by the purchaser, and items to be agreed between the purchaser and the manufacturer, at the time of enquiry and/or order, are given in Annex B. Recommendations for the installation of cables are given in Annex C. Guidance on the use of cables is given in Annex D.
