Characteristics Of Indoor And Outdoor Post Insulators For Systems With Nominal Voltages Greater Than 1000 V
出版:Verband Deutscher Elektrotechniker

专家解读视频
Applies to post insulators and post insulator units of ceramic material or glass intended for indoor or outdoor service, and to post insulators of organic material intended for indoor service in electrical installations or equipment operating on alternating current systems with a nominal voltage greater than 1000V and a frequency not greater than 100Hz. It may also be regarded as a provisional standard for insulators for use on direct current systems. The insulators covered by this standard are primarily intended for use in isolators (disconnectors) or as busbar or fues supports. This standard covers five types of post insulators.
