Abstract

341,535. Impregnating materials for electric insulation. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A.-(Assignees of Allgemeine Elektricitõts-Ges.; 2, Friedrich Karl-Ufer, Berlin.) Oct. 18, 1929, No. 31705. Convention date, Oct. 19, 1928. [Class 140.] Electrically insulating sheet material is formed of a fabric made from threads of spun paper which is impregnated with a, binding material such as a varnish containing oils, natural or artificial resins, phenol-formaldehyde condensation products, or the reaction products of multivalent alcohols and polybasic acids e.g. the condensation product of glycerine and pthallic acid anhydride. Other impregnating materials which may be used are cellulose varnishes such as ethyl-, benzyl-, acetyl- or nitro-, cellulose varnishes. The cellulose varnishes may be mixed with oils or resinous varnishes.
