ABSTRACT:
A reactor winding in the form of a high current, multi-turn, multi-layer insulated coil stack embracing an inner member of a magnetizable core assembly of a reactor is resiliently supported by the outer member of the core assembly by inserting a plurality of ripple spring sheets of non-magnetic material between the outer member and selected adjacent surfaces of the outer periphery of the windings. The inner core member is resiliently supported within the coil stack by an additional plurality of ripple spring sheets disposed between adjacent surfaces of the coil stack and inner core member. Ripple spring sheets are also positioned between adjacent surfaces of the inner and outer core members. The ripple spring sheets are preferably disposed between flat side sheets to provide uniform distribution of the spring forces.
