Abstract

642,184. Condensers. SPRAGUE ELECTRIC CO. Jan. 12, 1948, No. 946. Convention date, Dec. 28, 1946. Drawings to Specification. [Class 37] A process for producing an electrical con. denser comprises the moulding of a thermosetting resin about a flat or convolutely wound condenser having a dielectric of moist paper, drying the moulded unit and finally impregnating the condenser with a dielectric material. The impregnation may take place through an eyelet at one end of the unit which is then sealed with solder or, if the moulding resin contains a fibrous or porous filler, the removal of moisture and the impregnation of the dielectric may take place through the pores and fibres of the resin. Suitable fibrous or porous fillers are cotton linters, rag stock, asbestos, alkaline earths, fuller's earth, alpha-cellulose, wood flour, ground mica, rutile, &c. Suitable thermosetting resins are of the phenolformaldehyde series. Certain thermoplastic moulding materials such as natural and synthetic rubber, polyvinylaromatic resins, polyacrylates, and silicones may be used. The impregnant may comprise mineral oil, chlorinated diphenyls, vegetable oils such as castor oil, silicone oils or hydrocarbon waxes such as chlorinated naphthalenes and hydrogenated castor oil. Alternatively, the impregnant may be of the polymerizable compounds which may be impregnated as a liquid and subsequently polymerized in situ by the use of heat or catalysts.
