BS EN 62231-1 of EN 62231 belongs to a series of standards that covers characteristics of composite station post insulators for substations, enabling safe and stable distribution of electricity.
BS EN 62231-1 is the first part of the multi-series that specifies the main dimensions and values for mechanical and electrical characteristics of composite station post insulators.
BS EN 62231-1 is applicable to composite station post insulators for substations with ac voltages greater than 1000 V up to 245 kV.
BS EN 62231-1 also applies to composite station post insulators of similar design used in power stations of railway systems.
NOTE: The composite station post insulators covered by this standard are primarily intended for outdoor service, but can also be used indoors.
BS EN 62231-1 on composite station post insulators is relevant to:
A composite station post insulator is a post insulator consisting of a solid load bearing cylindrical insulating core, a housing and end fittings attached to the insulating core. They are essential for the safe and stable distribution of electricity generated at power plants.
BS EN 62231-1 provides users guidance on mechanical and dimensional characteristics, including maximum design cantilever load (MDCL), specified cantilever load (SCL), specified compression load (SCOL), specified tension load (STL), and more, enabling the standardization of dimensions and mechanical properties in composite station post insulators.
BS EN 62231-1 provides users guidance on mechanical and dimensional characteristics, electrical characteristics, designation, marking, tolerances and metal fitting arrangements, facilitating the classification, usability and performance in substations.
Compliance with BS EN 62231-1 enables users to develop and assess composite station post insulators, ensuring the operating stability, safety and longevity in substation applications.
