IEC 62271-209:2019作为IEC 62271-209:2019 RLV提供，其中包含国际标准及其红线版本，显示了与上一版本相比技术内容的所有变化。IEC 62271-209:2019涵盖了单相或三相布置中流体填充和挤压电缆与气体绝缘金属封闭开关设备(GIS)的连接组件，其中电缆终端为流体填充或干式，并且在电缆绝缘和开关设备的气体绝缘之间存在分离绝缘屏障。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)符合ISO/IEC指令第2部分（2016）和IEC 62271的新编号？1:2017; b)条款3:增加插入式电缆终端、填充压力和绝缘最小功能压力的定义； c)条款7:增加了插入式电缆终端的附加介电类型测试；还对电缆终端的绝缘子进行了压力类型试验和泄漏率试验； d)第12条:关于安全做法的新条款； e)第13条:关于产品对环境影响的新条款； f)新的资料性附件A:施加在电缆连接外壳法兰上的机械力。

IEC 62271-209:2019 is available as IEC 62271-209:2019 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 62271-209:2019 covers the connection assembly of fluid-filled and extruded cables to gas-insulated metal enclosed switchgear (GIS), in single- or three-phase arrangements where the cable terminations are fluid-filled or dry-type and there is a separating insulating barrier between the cable insulation and the gas insulation of the switchgear. 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) New numbering in accordance with ISO/IEC directives, Part 2 (2016) and to IEC 62271？1:2017;
b) Clause 3: addition of a definition for plug-in cable termination, filling pressure and minimum function pressure for insulation;
c) Clause 7: An additional dielectric type test for plug-in cable termination was added; also a pressure type test as well as a leak rate test on the insulator of a cable termination was implemented;
d) Clause 12: New clause about safety practices;
e) Clause 13: New clause about influence of the product on the environment;
f) New informative Annex A: Mechanical forces applied on the flange of the cable connection enclosure.
