A cooling system ( 11 ) is provided for electrical components ( 10, 90 ) in which passageways ( 21 ) are inserted in non-magnetic cores of the electrical components, and in which the passageways ( 21 ) provide both inflow and outflow of a cooling medium. The passageways ( 21 ) can be formed by drilling holes in a core of an electrical component or by mounting closed-end tubes ( 16-19 ) on a base plate-cooling manifold ( 20 ) or can be part of a conduit assembly ( 70 ). The tubes ( 16-19, 71 ) are split-flow closed-end tubes inserted from one end of the electrical component ( 10, 90 ). The tubes and passageways ( 16-19, 21, 71 ) may be partitioned into two halves or into two concentric portions. O-ring seals ( 28 ) are provided around the base of the tubes to seal the areas where the passageways communicate with hollow portions of base plates for supplying the cooling medium.
