1 Scope

This part of GB/T .20139 specifies the required level of electrical insulation system (EIS) components to adjust the heat resistance assessment of the required test Inspection procedures.

This section applies to EIS using electrical equipment for forming windings.

The test procedures in this section are determined by comparing the performance of the insulation system and the reference insulation system. The selected insulation system shall have the performance and operating experience in accordance with IEC 60505, or have complied with the requirements of IEC 60050-250 and IEC 60034-18-31.:2012 the procedure is evaluated.
