DANSK DSF/IEC 61892-4 ED2 PDF

This part of IEC 61892 is applicable to the selection of electrical cables intended for fixed electrical systems in mobile and fixed offshore units, including pipeline, pumping or 'pigging' stations, compressor stations and single buoy moorings, used in the offshore petroleum industry for drilling, production, accommodation, processing, storage and offloading purposes. This document specifies requirements such as those of: – 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; – short circuit withstand capacity. This document gives information to topics such as: – jet fire test for hydrocarbon (HCF) resistant cables The reference to fixed electrical systems includes those that are subjected to vibration due to the movement of the unit, e.g. cables installed on a drag chain, and not those that are intended for repeated flexing. The standard does not cover flexible cables, e.g. those used on drilling deck, e.g. for top-drive, and 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; – data, telecommunication and radio frequency cables
