The Institute for Standardization of Bosnia and Herzegovina, through its Technical Committee BAS/TC 8, Insulation coordination, high-voltage testing, and instrument transformers, has adopted, by translation method, the second edition BAS EN IEC 61952-1:2024, Insulators for overhead lines - Composite line post insulators for AC systems with a nominal voltage greater than 1,000 v - Part 1: definitions, end fittings and designations, which is a translation of the English version of the European standard EN IEC 61952-1:2019.

BAS EN IEC 61952-1:2024, which is part of the IEC 61952 series, is applicable to composite line post insulators for AC overhead lines with a nominal voltage greater than 1,000 V AC and a frequency not greater than 100 Hz.

It also applies to lines post insulators of similar design used in substations or on electric traction lines.

This document applies to line post insulators of composite type, generally with metallic couplings, with and without a base plate. It also applies to such insulators when used in complex structures. It does not apply to hollow insulators adapted for use as line post insulators.

The object of this document is to specify the main dimensions of the couplings to be used on the composite line post insulators in order to permit the assembly of insulators or fittings supplied by different manufacturers and to allow, whenever practical, interchangeability with existing installations.

It also specifies a standard designation system for composite line post insulators.

The original texts of the standard were prepared by the IEC Technical Committee IEC/TC 36, Insulators.
