Abstract
An epoxy resin composition is disclosed for joining dissimilar materials. The identified epoxy resin compositions can fee used to seal metallic and non-metallic components of a capacitor. Specifically the epoxy resin composition can be applied to joints between a non-metallic capacitor bushing and a metallic tank cover and metallic terminal cap. Once the epoxy resin composition is cored, it can provide a seal that can withstand the stresses and environmental conditions to which a capacitor is subjected.
Claims20
A capacitor tank comprising:
- an insulating hushing comprising substantially glass, ceramic, polymer, or glazed material;
- a metallic tank cover;
- a casing attached to the metallic tank cover, the casing to contain a fluid comprising one or more aromatic compounds;
- and
- a cured seal between the insulating bushing and the metallic tank cover,
- wherein the cured seal comprises an epoxy resin composition,
- wherein the epoxy resin composition comprises a curing agent and one or both of a phenol novoiac epoxy and a bisphenol A epoxy, and
- wherein the cured seal is exposed to the fluid comprising one or more aromatic compounds when the capacitor tank is completely assembled.
A capacitor tank comprising:
- an insulating bushing;
- a metallic tank cover;
- a casing attached to the metallic tank cover, the casing to contain a dielectric fluid;
- and
- a cured seal between the insulating bushing and the metallic tank cover,
- wherein the cured seal comprises an epoxy resin composition,
- wherein the epoxy resin composition comprises a curing agent and one or both of a phenol novolae epoxy and a bisphenol A epoxy, and
- wherein the cured seal is exposed to the dielectric fluid when the capacitor tank is completely assembled.
