The methods described in this technical specification can be used for the measurement of the wettability of the shed and housing material of composite insulators for overhead lines, substations and equipment or ceramic insulators covered or not covered by a coating. The obtained value represents the wettability at the time of the measurement. The determination of the ability of water to wet the surface of insulators may be useful to evaluate the condition of the surface of insulators in service, or as part of the insulator testing in the laboratory.

Prescribes specified values for the mechanical characteristics of the composite string insulator units. Defines the main dimensions of the couplings to be used on the composite string insulator units in order to permit the assembly of insulators of fittings supplied by different manufacturers and to allow, whenever practical, interchangeability with existing installations. It also defines a standard designation system for composite string insulator units. The contents of the corrigendum of November 2007 have been included in this copy.

Frequently Asked Questions

WG 10 is a Technical Committee within the International Electrotechnical Commission (IEC). It is named "TC 36/WG 10". This committee has published 274 standards.

WG 10 develops IEC standards in the area of Information technology. Currently, there are 274 published standards from this technical committee.

The International Electrotechnical Commission (IEC) is the world's leading organization for the preparation and publication of international standards for electrical, electronic, and related technologies. Founded in 1906, the IEC provides a global platform for companies, industries, and governments to meet, discuss, and develop the international standards they require.

A Technical Committee (TC) in IEC is a group of experts responsible for developing international standards in a specific technical area. TCs are composed of national member body delegates and work through consensus to create standards that meet global industry needs. Each TC may have subcommittees (SCs) and working groups (WGs) for specialized topics.
