Abstract
The present disclosure relates to insulation systems. The teachings thereof may be embodied in an insulation system for an electrical machine. For example, an insulation system may comprise: solid insulation materials; an impregnating resin having oxirane functionalities; a depot accelerator distributed throughout the solid insulation materials; and a catalyst for initiating hardening of the impregnating resin, wherein the catalyst is at least partly in gaseous form under hardening conditions.
Claims12
An insulation system, comprising:
- porous solid insulation materials;
- an impregnating resin distributed throughout the porous solid insulation materials, the impregnating resin having oxirane functionalities;
- a depot accelerator distributed throughout the porous solid insulation materials and physically separate from the impregnating resin until an impregnating process is performed;
- and
- a catalyst for initiating hardening of the impregnating resin, wherein the catalyst is distinct from the depot accelerator and provided in a gaseous form to external surfaces of the insulation materials including the impregnating resin to promote hardening in regions proximate the external surfaces of the insulation materials.
