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;
---------------------- Page: 9 ----------------------
– 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 reduction in GIS

cable termination housing;
– the lengths l7 and l8 have been modified;

– changes in the text in relation to minimum functional pressure for insulation p (Table 1

has been removed);
– the limit of 170 kV for 3-phase application was deleted (Subclause 5.2);
– Figure 5 was deleted.
The text of this standard is based on the following documents:
FDIS Report on voting
17C/405/FDIS 17C/412/RVD

Full information on the voting for the approval of this standard can be found in the report on

voting indicated in the above table.

This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.

A list of all the parts in the IEC 62271 series, under the general title High-voltage switchgear

and controlgear, can be found on the IEC website.

The committee has decided that the contents of this publication will remain unchanged until

the maintenance result date indicated on the IEC web site under "http://webstore.iec.ch" in

the data related to the specific publication. At this date, the publication will be

• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

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
1 Scope

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.

The purpose of this standard is to establish electrical and mechanical interchangeability

between cable-terminations and the gas-insulated metal-enclosed switchgear and to

determine the limits of supply. It complements and amends, if necessary, the relevant IEC

standards. For the purpose of this standard the term "switchgear" is used for "gas-insulated

metal enclosed switchgear".

It does not cover directly immersed cable terminations, as described in CIGRE brochure 89.
