GB/T 26218.2-2010 — This section GB/T 26218 under filthy conditions applicable to the exchange system is determined by the choice of porcelain and glass insulators and dimensions.
This section it specifies the set insulators under certain environmental contamination derived its method for determining the potential performance of specific guidelines and principles.
GB/T 26218.1 apply to this section. Infrastructure and methods of this section in GB/T 26218.1 described in detail.
This section provides the user with the aim of. - Contamination from the field (SPS) level is determined with reference to a unified specific creepage distance (USCD); - assess the suitability of various insulator shape; - RUSCD on insulator on the shape, size and position correction was necessary in order to determine USCD; - If required, to determine the performance of insulators verify the selected appropriate test methods and parameters.
