Composite hollow insulators - Pressurized and unpressurized insulators for use in electrical equipment with AC rated voltage greater than 1 000 V AC and D.C. voltage greater than 1500V - Definitions, test methods, acceptance criteria and design recommendations (IEC 61462:2023)
EN IEC 61462:2023

This International Standard applies to composite hollow insulators consisting of a load-bearing insulating tube made of resin impregnated fibres, a housing (outside the insulating tube) made of elastomeric material (for example silicone or ethylene-propylene) and metal fixing devices at the ends of the insulating tube. Composite hollow insulators as defined in this standard are intended for general use (unpressurized) or for use with a permanent gas pressure (pressurized). They are intended for use in both outdoor and indoor electrical equipment operating on alternating current with a rated voltage greater than 1 000 V a.c. and a frequency not greater than 100 Hz or for use in direct current equipment with a rated voltage greater than 1 500 V d.c.
The object of this standard is:
- to define the terms used;
- to prescribe test methods;
- to prescribe acceptance criteria.
Hollow insulators are integrated into electrical equipment which is electrically type tested as required by the applicable equipment standard. So, it is not the object of this standard to prescribe dielectric type tests because the withstand voltages and flashover behaviour are not characteristics of the hollow insulator itself but of the apparatus of which it ultimately forms a part.
All the tests in this standard, apart from the thermal-mechanical test, are performed at normal ambient temperature. This standard does not prescribe tests that may be characteristic of the apparatus of which the hollow insulator ultimately forms a part.
Composite hollow insulators are intended for use in electrical equipment, such as, but not limited to:
- HV circuit-breakers,
- switch-disconnectors,
- disconnectors,
- station posts,
- disconnecting circuit breakers,
- earthing switches,
- instrument- and power transformers,
- bushings,
- cable terminations.
Additional testing defined by the relevant IEC equipment standard may be required.

This International Standard applies to composite hollow core station post insulators consisting of a load-bearing insulating tube (core) made of resin impregnated fibres, insulating filler material (solid, liquid, gaseous - pressurized or unpressurized), a housing (outside the insulating tube) made of polymeric material (for example silicone or ethylene-propylene) and fixing devices at the ends of the insulating tube. Composite hollow core station post insulators as defined in this standard are intended for general use in substations in both, outdoor and indoor environments, operating with a rated AC voltage greater than 1 000 V a.c. and a frequency not greater than 100 Hz or for use in direct current systems with a rated voltage greater than 1 500 V.d.c.
The object of this standard is:
to define the terms used;
to prescribe test methods;
to prescribe acceptance criteria.
All the tests in this standard, apart from the thermal-mechanical test, are performed at normal ambient temperature. This standard does not prescribe tests that are characteristic of the apparatus of which the composite hollow core station post insulator ultimately may form a part (e.g. disconnector switch, reactor support, HVDC valves).

Insulators for overhead lines with a nominal voltage above 1000 V - Ceramic insulators for AC systems - Characteristics of insulator units of the long rod type (IEC 60433:2021)
EN IEC 60433:2021

This International Standard is applicable to string insulator units of the long rod type with
insulating parts of ceramic material intended for use in AC overhead power lines with a
nominal voltage greater than 1 000 V and a frequency not greater than 100 Hz. It is also
applicable to insulators of similar design, used in substations.
This document is applicable to ceramic string insulator units of the long rod type, either with a
clevis end fitting at both ends for coupling with a tongue, or with a socket end fitting at both
ends for coupling with a pin ball.
The object of this document is to prescribe specified values for electrical and mechanical
characteristics, and for the principal dimensions of ceramic string insulator units of the long
rod type.
This document is applicable to string insulator units for use on overhead lines situated in
lightly polluted areas, and the creepage distances given in Table 1 have been established
accordingly, using the IEC TS 60815-2 recommendation of 27,8 mm/kV for SPS class.
However, shorter creepage distances are applicable for use in some non-polluted areas. If
specific operating conditions require or allow non-standard (longer or shorter) creepage
distances, the mechanical characteristics as well as the lengths L (see Clause 4) of this
document are intended to be used unless the need for exceptionally long creepage distances
requires values of L greater than those given in Table 1. In the case of special requirements,
e.g. very heavy polluted areas and for other particular or extreme environmental conditions, it
may be necessary for certain dimensions to be changed.
As far as reasonably applicable, this document is also applicable to be applied to similar
insulator units outside the scope of this standard, such as insulators for electric traction lines.
This document does not include tests on insulators and dimensions of end fittings.
Ball and socket couplings are covered by IEC 60120, clevis and tongue couplings by
IEC 60471.
NOTE 1 For the definition of site pollution severity, see applicable part of IEC TS 60815.
NOTE 2 The term "ceramic" is used in this document to refer to porcelain materials and, contrary to North
American practice, does not include glass.

EN IEC 60305:2021

This International Standard applies to string insulator units of the cap and pin type with
insulating parts of ceramic material or glass, intended for AC 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 document applies to string insulator units of the cap and pin type either with ball and
socket couplings or with clevis and tongue couplings.
This document 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 DC systems
may also need different dimensions. In any case, it is applicable that the standardized
mechanical characteristics of this document and coupling sizes are retained.
The object of this document is to prescribe specified values for the mechanical characteristics
and for the main dimensions of string insulator units of the cap and pin type.
The power frequency, lightning impulse and puncture withstand voltages of string insulator
units are not specified in this document. IEC 60383-1 gives the electrical characteristics which
define string insulator units; their values are agreed between purchaser and manufacturer.
Ball and socket couplings are covered by IEC 60120, clevis and tongue couplings by
IEC 60471.

This international standard is applicable to locking devices used with ball and socket
couplings of string insulator units and used with the corresponding metal fittings standardized
in IEC 60120, when they are supplied separately.
When these locking devices are supplied with an insulator or fitting, they are considered as an
integral part of it. In this case, the relevant test is to be included with those of insulators, as
specified in IEC 60383-1 and IEC 61325. On request, a certificate is to be delivered
confirming that the tests on locking devices as specified in this document have been carried
out. The locking devices are usually supplied with the insulator or corresponding metal fittings.
The object of this document is
• to define the shapes and some standard dimensions for locking devices,
• to define the test methods for locking devices,
• to state the acceptance conditions for supply,
• to give other dimensions for guidance of manufacturing only.
The object of this document does not include the specification of the nature of the material,
and the material covered by the scope of this document does not have a surface coating for
