Post insulators on board of rolling stock
1 Scope
This standard specifies the classification and model, environmental conditions, technical requirements, test, as well as marking, packaging and storage of post insulators on board of rolling stock.
This standard is applicable to the outdoor post insulators for supporting pantograph and busbar of electric rolling stock and EMUs with an AC traction system of nominal voltage of 25kV (hereinafter referred to as insulators). This standard may serve as a reference for other types of roof insulators.
