IEC 61466-1-2016
Composite string insulator units for overhead lines with a nominal voltage greater than 1 000 V - Part 1: Standard strength classes and end fittings (Edition 2.0)
IEC 61466-1-2016 发布历史
This part of IEC 61466 is applicable to composite string insulator units for a.c. overhead lines with a nominal voltage greater than 1000 V and a frequency not greater than 100 Hz. It also applies to insulators of similar design used in substations or on electric traction lines. This standard applies to string insulator units of composite type with ball@ socket@ tongue@ clevis@ Y-clevis or eye couplings@ or a combination thereof. The object of this standard is to prescribe specified values for the mechanical characteristics of the composite string insulator units and define the main dimensions of the couplings to be used on the composite string insulator units 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 defines a standard designation system for composite string insulator units. NOTE 1 General definitions and methods of testing are given in IEC 61109. NOTE 2 Only the dimensions necessary for assembly of the couplings are dealt with in this International Standard. Properties of material and working loads are not specified. The coordination of dimensions of the end fittings with the strength classes is specified in Clause 7.
