This part of IEC 62332, which is a technical specification, is applicable to EIS containing solid and liquid components where the thermal stress is the dominant ageing factor, without restriction to voltage class.<\/p>\n

This part specifies a sealed tube test procedure for the thermal evaluation and qualification of electrical insulation systems (EIS). One aspect of this procedure is to also provide a method to assign thermal classifications to materials used in EIS where solid and liquid components are both used. This procedure describes a comparative ageing method whereby a reference system composed of kraft paper and mineral oil is compared to a candidate system of any combination of solid and insulating liquid. The test procedures in this part are specifically applicable to liquid immersed transformer insulation systems.<\/p>\n

Similar procedures should also work for other electrotechnical devices with a combination of liquid and solid components, such as bushings, cables or capacitors, but this will be added as additional parts once experience is gained using this technical specification.<\/p>\n
