IEC 62271-209 Ed. 2.0 b:2019

High-voltage switchgear and controlgear - Part 209: Cable connections for gas-insulated metal-enclosed switchgear for rated voltages above 52 kV - Fluid-filled and extruded insulation cables - Fluid-filled and dry-type cable-terminations

EC 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.
