Abstract
Abstract An electrical device body including an electrode and a radiation semi-cured or cured polymer containing material. The electrode is formed into a configuration such as a convolutely wound electrical device body. The radiation semi-cured or cured polymer containing material is disposed over the body to help maintain the configuration of the body. A method of making the electrical device body including the steps of applying radiation curable polymer containing material to an electrode formed into a configuration such as a convolutely wound body configuration, irradiating applied material to semi-cure or completely cure the applied material and help maintain the configuration of the body. High energy irradiation from an energy source such as ultra-violet light or an electron beam is used to cross-link or cure applied polymeric material.

Claim 8
Dependent Claim
33 words
A capacitor body including convolutely wound electrodes and a length of material at least radiation semi-cured disposed at the periphery of the body to help maintain the body as a convolutely wound body.
Claim 9
Dependent Claim
33 words
A capacitor body including convolutely wound electrodes and a length of material at least radiation semi-cured disposed at the periphery of the body to help maintain the body as a convolutely wound body.
Claim 10
Dependent Claim
51 words
A method of making the electrical device body of claim 1, including the steps of forming the electrode into a configuration, applying irradiation curable material to the periphery of the electrode, and irradiating the material to at least semi-cure the material, the material helping to maintain the configuration of the electrode.
