AS/NZS 4435.2:1999
Insulators - Composite for overhead power lines - Voltages greater than 1000 V a.c. - Standard strength classes and end fittings for string insulator units
Specifies values for the mechanical characteristics of composite string insulator units. This Standard defines the main dimensions of the couplings to be used on composite string insulator units to allow interchangeability of units or insulators supplied by different manufacturers and to allow, whenever practicable, interchangeability with existing installations. This Standard is based on but not equivalent to and has been reproduced from IEC 61466-1:1997.
