Scope:

1.1 General

This standard is applicable to - ceramic and glass hollow insulators intended for general use in electrical equipment; - ceramic hollow insulators intended for use with a permanent gas pressure in switchgear and controlgear.

These insulators are intended for indoor and outdoor use in electrical equipment, operating on alternating current with a rated voltage greater than 1 000 V and a frequency not greater than 100 Hz or for use in direct-current equipment with a rated voltage of greater than 1 500 V.

The hollow insulators are intended for use in electrical equipment, for example: - circuit-breakers, - switch-disconnectors, - disconnectors, - earthing switches, - instrument transformers, - surge arresters, - bushings, - cable sealing ends, - capacitors.

It is not the object of this standard to prescribe dielectric type tests because the withstand voltages are not characteristics of the hollow insulator itself but of the apparatus of which it ultimately forms a part.

1.2 Hollow insulators or hollow insulator bodies intended for general use

Hollow insulators or insulator bodies of ceramic material or glass, intended for use - without pressure; - with permanent pressure .50 kPa gauge; - with permanent gas pressure >50 kPa gauge in combination with an internal volume < 1 l (1 000 cm3); - with permanent hydraulic pressure.
