ABSTRACT:
A rotatable connector for heavy electric currents has a first annular flange unit coaxially in the annular space of a second annular flange unit. Inner and outer fluid-cooled conductors physically and electrically connect to the first flange unit. The conductors and first flange unit are rotatable relative to the second flange unit about the axis of the flange units. U-shaped stranded wires are embedded at their opposite ends in corresponding first and second flanges of the first and second flange units. The first flange of the first flange unit is cooled by the fluid cooling the outer conductor and the other flanges of the units are separately fluid cooled. The combination of embedding the stranded wires in the flanges and fluid cooling the flanges keeps the stranded wires cool enough for carrying heavy electric currents without corroding contact of the stranded wires with the cooling fluid.
