Organization: IEC
Publication Date: 1 July 2020
Status: active
Page Count: 24
ICS Code (Power transmission and distribution lines): 29.240.20
ICS Code (Insulators): 29.080.10
scope:

This international standard applies to string insulator units of the cap and pin type and also of the long rod type as well as the fittings used with such insulators.

The object of this document is to define the dimensions of a series of clevis and tongue couplings to permit the assembly of insulators or fittings supplied by different manufacturers.

NOTE 1 IEC 60305 gives the coordination between the standardized dimensions of Table 1 and the strength classes of cap and pin insulator. IEC 60433 gives the coordination between the standardized dimensions of Table 2 and the strength classes of long rod insulators.

NOTE 2 If the dimensions given in Table 1 are not sufficient, higher strength classes are given in IEC 60305.
