Description / Abstract:

This Standard specifies the mechanical, dimensional and electrical requirements for ceramic and glass type station post insulators for indoor or outdoor service in electrical installations or equipment operating with a rated voltage greater than 1000 V and a rated frequency not greater than 100 Hz.

This Standard covers insulators intended primarily for use as support or operating elements in switching equipment, or as bus bar or other equipment supports.

Note: The electrical and mechanical characteristics for direct current insulators are similar to the comparable characteristics for alternating current insulators. However, due to the unidirectional voltage stress, special attention needs to be paid to the pollution susceptibility and to the location of insulators in a direct current scheme.
