Abstract
A transformer assembly and a method of producing the same are provided. The transformer assembly includes a housing, transformer oil, and a plurality of coils of electrically conductive wire. The transformer oil is disposed within the housing. The coils of electrically conductive wire are disposed in the housing and in contact with the transformer oil. A cross-linked aliphatic polyamide insulation material configured to electrically insulate the electrically conductive wire. The insulation material includes stabilizing compounds that provide thermal and chemical stability for the insulation material.
Claims6
A transformer assembly, comprising:
- a housing;
- a first insulation material comprising cellulose;
- a plurality of coils of electrically conductive wire disposed in the housing;
- and
- an insulation material configured to electrically insulate the electrically conductive wire, the insulation material consisting essentially of an aliphatic polyamide that includes at least one cross-linker and one or more stabilizing compounds that provide thermal stability, or chemical stability, or both for the insulation material, the at least one cross-linker comprising a carboxylic anhydride group and ethynyl moieties.
