This document specifies requirements such as those concerning – types of cables, – voltage rating of cables, – cables and wiring for interconnection of equipment, – current-carrying capacities for continuous service, – correction factors for different ambient temperature and for short time duty, and – short-circuit withstand capacity. This document also gives information on the jet fire test for hydrocarbon (HCF) fire resistant cables. The reference to fixed electrical systems includes those subjected to vibration due to the movement of the unit, for example, cables installed on a drag chain, and not those intended for repeated flexing. This document does not cover flexible cables, for example, those used on drilling decks for top-drive, or cables for portable equipment. This document is applicable for cables with a rated voltage up to and including 18/30 kV AC and makes reference to cable standards developed by SC 18A. For higher voltages, relevant standards developed by TC 20 are applicable. This document does not apply to – optical fibre cables, – sub-sea and umbilical cables;, – cables supplying downhole pumps, and – data, telecommunication and radio frequency cables. This second edition cancels and replaces the first edition published in 2007. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) construction requirements for cables have been removed; reference is made to relevant standards from Subcommittee (SC) 18A; b) reference is made to standards from IEC TC 20 for cables with rated voltage above 30 kV; c) tables for current-carrying capacities for defined installations have been removed; reference is made to relevant standards from IEC TC 64; d) requirements as to the sizes of earth continuity conductors not contained in a cable have been moved to IEC 61892-6; e) requirements as to fire stops have been deleted; f) requirements as to tests for cables exposed to drilling fluids have been removed; reference is made to relevant standards from IEC SC 18A; g) the procedure for tests of jet fire resistant cables has been updated; h) requirements as to the design of cable systems have been moved to IEC 61892-2; i) requirements in relation to the installation of cables have been moved to IEC 61892-6.
