IEC 61466-2:1998/AMD2:2018

IEC 61466-2:1998/AMD2:2018 is a supporting amendment to the parent document for composite string insulator units for overhead lines with a nominal voltage greater than 1 000 V, focused on dimensional and electrical characteristics. It is relevant when teams need to verify whether the updated requirements affect product definition, technical review, or conformity assessment activities. For engineering, procurement, and compliance workflows, IEC 61466-2:1998/AMD2:2018 helps align documented evaluation with the amended technical basis used for specification control and validation.

What is IEC 61466-2:1998/AMD2:2018?

This document is Amendment 2 to IEC 61466-2:1998, so it should be read as a modifying reference connected to the parent technical document rather than as a standalone specification. Based on its title, it addresses dimensional and electrical characteristics for composite string insulator units used on overhead lines above 1 000 V. In practice, that makes it relevant for technical assessment, product evaluation, and compliance workflows where the exact characteristics of insulator units must be checked against updated requirements.

Applications of IEC 61466-2:1998/AMD2:2018

Organizations may use IEC 61466-2:1998/AMD2:2018 during engineering documentation review, supplier qualification, and laboratory evaluation related to overhead line insulator units. It is particularly useful where dimensional checks, electrical performance review, or conformity assessment preparation must follow the amended reference path tied to IEC 61466-2:1998. Utility asset teams, manufacturers, test laboratories, and procurement groups can use it to support consistent product evaluation, verification activities, and controlled technical documentation across quality workflows.

Why is IEC 61466-2:1998/AMD2:2018 important?

Amendments like IEC 61466-2:1998/AMD2:2018 matter because they define how the parent document should be interpreted and applied in current technical and compliance processes. For overhead line insulator projects, that can affect safety review, testing consistency, and procurement decisions where dimensional and electrical characteristics must be validated against the latest accepted basis. Using the amendment alongside the parent reference supports operational consistency, reduces conformity assessment risk, and helps maintain reliable engineering validation and documented evaluation.
