Abstract: PROBLEM TO BE SOLVED: To realize a method for producing a conductor bar having an superior insulation property in a short time. SOLUTION: A not wrapped conductor bar 2 is wrapped with a thermoplastic insulation tape, and it is inserted into a pressure-proof molding die 1. The wrapped conductor bar 2 is dried, and then it is heated to a high temperature higher than the yield point of the thermoplastic insulation tape. During the yield of the thermoplastic plastic, the conductor bar 2 is placed under pressure in the molding die 1 and the residual gas in the thermoplastic plastic dissolves at an atomic level. Then the conductor bar 2 is cooled under pressure and solidified again. According to this method, the conductor bar 2 having a constant and superior insulation property can be manufactured simply and economically.
