IEC 61892-4:20 19适用于海上石油工业中用于钻井、生产、住宿、加工、储存和卸载目的的移动式和固定式海上装置（包括管道、泵送或“清管”站、压缩机站和单浮标系泊装置）固定电气系统的电缆选择。 本文件规定了以下要求: -电缆的类型， -电缆的额定电压， -用于设备互连的电缆和布线， -用于连续服务的载流能力， -用于不同环境温度和用于短时间占空比的校正因子，以及 -短路耐受能力。 本文件还提供了碳氢化合物（HCF）耐火电缆喷射火灾试验的信息。对固定电气系统的引用包括那些由于单元的移动而受到振动的系统，例如安装在拖链上的电缆，而不是那些旨在重复弯曲的系统。本文件不涵盖柔性电缆，例如，用于顶部驱动的钻井平台上的电缆或便携式设备的电缆。 本文件适用于额定电压不超过18/30 kV交流电的电缆，并参考SC 18A制定的电缆标准。 对于更高的电压，适用TC 20制定的相关标准。 本文件不适用于 -光缆， -海底和脐带缆；, -供应井下泵的电缆，以及 -数据、电信和射频电缆。 这第二版取消并取代了2007年出版的第一版。本版构成技术修订版。 与上一版相比，此版本包括以下重大技术变更: a)电缆的施工要求已被取消；参考小组委员会（SC）18A的相关标准； b)对于额定电压在30kV以上的电缆，参考IEC TC 20的标准； c)已删除规定装置的载流能力表；参考IEC TC 64的相关标准； d)关于不包含在电缆中的接地连续性导体尺寸的要求已移至IEC 61892-6； e)删除了有关停火线的规定； f)关于暴露于钻井液的电缆的测试要求已被删除；参考IEC SC 18A的相关标准；g)更新了喷射耐火电缆的测试程序； h)有关电缆系统设计的要求已移至IEC 61892-2； i)与电缆安装相关的要求已移至IEC 61892-6。

IEC 61892-4:2019 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 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.
