METHOD FOR MANUFACTURING OF ENAMELLED WIRES Russian patent published in 2012 - IPC H01B13/16 

FIELD: electricity.

SUBSTANCE: on the basis of a film-generating varnish PE-933 of grade B an electrophoretic composition is created, which comprises the following components, ml/l: varnish PE-939 of grade B - (290÷300); 1% - liquid ammonia 1 % - NH₄OH - (110÷120); dioxane (C₄H₈O₂) - balance. Previously a certain value of current density is selected, a section of a moving wire is submerged into the specified electrophoretic composition, the wire is stopped, positive potential is supplied to it relative to a grounded body of a unit of enamel insulation application, and its value provides for a certain value of anophoresis current, an enamel insulation film is deposited onto a wire section submerged into the electrophoretic composition for a time determined in accordance with the given ratio, then the wire is moved again, the wire is again stopped, the enamel insulation film is electrically deposited onto the subsequent section of wire, such alternating process is continued until completion of the enamelling process.

EFFECT: power input reduction.
