MOLDED STRANDED WIRE CONDUCTOR AND COIL USING IT

摘要

PROBLEM TO BE SOLVED: To facilitate molding of a square molded stranded wire conductor and to reduce A.C. loss in an A.C. environment. SOLUTION: A round cooling pipe 1 made of a stainless steel pipe is disposed at the center and linear insulating members 2 each formed by impregnating an epoxy resin in a glass fiber having an outside diameter of about 3.5 mm are longitudinally attached to the diagonal four corners of the circumferential part of the cooling pipe 1. In the circumference of the cooling pipe 1, nineteen conductors 3 each made of a soft aluminum wire having an outside diameter of 3.1 mm are concentrically stranded at a pitch around 11.2 times of a layer core diameter. The stranded wire conductor 4 thus provided is so compression- molded that its longitudinal and lateral widths are respectively set to around 19 mm by a roller die or the like.
