INSULATORS FOR OVERHEAD LINES
WITH A NOMINAL VOLTAGE ABOVE 1 000 V -
Ceramic or glass insulator units for a.c. systems -
Characteristics of insulator units of the cap and pin type
FOREWORD

The IEC (International Electrotechnical Commission) is a worldwide organization for standardization

comprising all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.

3) The documents produced have the form of recommendations for international use and are published in the

form of standards, technical reports or guides and they are accepted by the National Committees in that

sense.

4) In order to promote international unification, IEC National Committees undertake to apply IEC International

Standards transparently to the maximum extent possible in their national and regional standards. Any

divergence between the IEC Standard and the corresponding national or regional standard shall be clearly

indicated in the latter.

5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any

equipment declared to be in conformity with one of its standards.

6) Attention is drawn to the possibility that some of the elements of this International Standard may be the

subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

International Standard IEC 305 has been prepared by sub-committee 36B: Insulators for

overhead lines, of IEC technical committee 36: Insulators. This fourth edition cancels and

replaces the third edition published in 1978 of which it constitutes a technical revision in order

to introduce characteristics of cap and pin insulators for polluted areas.
The text of this standard is based on the following documents:
DIS Report on voting
36B/149/RVD
36B/139/DIS

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

voting indicated in the above table.

INSULATORS FOR OVERHEAD LINES
WITH A NOMINAL VOLTAGE ABOVE 1 000 V -
Ceramic or glass insulator units for a.c. systems -
Characteristics of insulator units of the cap and pin type
1 Scope and object

This International Standard applies to string insulator units of the cap and pin type with

insulating parts of ceramic material or glass, intended for a.c. overhead lines with a nominal

voltage greater than 1 000 V and a frequency not greater than 100 Hz. It also applies to

insulators of similar design used in substations.

This standard applies to string insulator units of the cap and pin type either with ball and socket

couplings or with clevis and tongue couplings.

This standard applies to string insulator units for use on overhead lines in clean areas and

polluted areas. For use in areas characterized by very heavy pollution levels and for other

particular or extreme environmental conditions, it may be necessary for certain dimensions to

be changed and insulator units having different creepage distances, spacing and forms may be

preferred (for example, flat profile, hemispherical etc.). Insulators for use on d.c. systems may

also need different dimensions. In any case, it is recommended tha
