IEC 62271-209:2019 RLV contains both the official IEC International Standard and its Redline version. The Redline version is not an official document, it is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its 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.
