Appareillage à haute tension - Partie 301: Normalisation dimensionelle des bornes à haute tension
Le CEI/TR 62271-301:2009 s'applique à l'appareillage à haute tension, notamment aux disjoncteurs, sectionneurs et interrupteurs. Toutefois, son application à d'autres matériels n'est pas exclue. On peut n'indiquer aucune relation entre les dimensions et le courant nominal en service continu. Cette deuxième édition annule et remplace la première édition publiée en 2004 et constitue une révision technique. Les principaux changements par rapport à l'édition précédente sont l'ajout de l'Article 2, Termes et définitions, ainsi que des Figures 2 à 7.

HIGH-VOLTAGE SWITCHGEAR AND CONTROLGEAR –
Part 301: Dimensional standardisation of high-voltage terminals
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.
The main task of IEC technical committees is to prepare International Standards. However, a
technical committee may propose the publication of a technical report when it has collected
data of a different kind from that which is normally published as an International Standard, for
example "state of the art".
IEC 62271-301, which is a technical report, has been prepared by subcommittee 17A: High-
voltage switchgear and controlgear, of IEC technical committee 17: Switchgear and
controlgear.
This second edition cancels and replaces the first edition published in 2004 and constitutes a
technical revision.
The main changes with respect to the previous edition are the addition of Clause 2, Terms
and definitions, as well as Figures 2 through 7.

This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
A list of all parts of IEC 62271series, published under 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

4 HV terminals with rectangular shape
The recommended dimensions for rectangular HV terminals should be restricted to the
diameters of and the distances between the holes.
The dimensions are as follows:
– hole diameters: 14 mm, 16 mm, 17 mm, 18 mm 19 mm and 22 mm;
– distance between holes: 40 mm, 45 mm, 50 mm and 60 mm (centre-to-centre).
NOTE A hole diameter of 14,3 mm and distance between holes of 44,5 mm exist in certain countries.
Any possible combination of these dimensions is permitted.
The distance between holes should be applied to two adjacent holes, both along the abscissa
or ordinate.
Typical examples of hole arrangements are given in Figures 2 through 7.
