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

This standard 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.

Appareillage à haute tension - Partie 209: Raccordement de câbles pour appareillage sous enveloppe métallique à isolation gazeuse de tension assignée supérieure à 52 kV - Câbles remplis d'un fluide ou à isolation extrudée - Extrémité de câble sèche ou remplie d'un fluide

La présente norme est applicable à l'assemblage de raccordement de câbles remplis d'un fluide ou à isolation extrudée à l'appareillage sous enveloppe métallique à isolation gazeuse (PSEM), dans une disposition unipolaire ou tripolaire. Les extrémités de câble sont à remplissage de fluide ou sèches et une séparation isolante se trouve entre le fluide d'isolation du câble et l'isolation gazeuse de l'appareillage.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of

patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 62271-209 has been prepared by subcommittee 17C: High-voltage
switchgear and controlgear assemblies, of IEC technical committee 17: Switchgear and
controlgear.
This first edition of IEC 62271-209 cancels and replaces the second edition of IEC/TS 60859
and constitutes a technical revision. The changes from IEC/TS 60859 are as follows:
– the minimum voltage rating was changed from “72,5 kV” to ”above 52 kV”;
– the current rating was increased to 3150 A;

– 4 – 62271-209 © IEC:2007
– simplifications and modifications of the dimension tables in Figure 2 and Figure 4 such as

diameters for 123 kV to 170 kV have been adopted in order to accommodate larger cable

cross-sections; new dimensions accept old terminations, new terminations may not meet

old GIS standards;
– the following dimensions have been deleted: l1, l3 as well as note 3 on Figure 4;

– in Figure 4, new dimensions have been adopted for the voltage range from 245 kV to

300 kV, interchangeability for 245 kV to 300 kV is not maintained due to reduc
