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
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 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 (see Figure D.1 and Figure D.2 for examples).
The object of this document is to define the terms used, to specify test methods; and to specify acceptance criteria.
This document distinguishes between design tests and type tests because several general characteristics of a specific design and specific combinations of materials do not vary for different insulator types.
This new edition cancels and replaces the previous edition published in 2007.
This edition includes the following significant technical changes with respect to the previous edition:
