A coil is made having a plurality of layers of adjacent metal conductor windings subject to voltage stress, where the windings have insulation therebetween containing a small number of minute disposed throughout its cross-section, where the voids are voids filled with SF.sub.6 gas to substitute for air or other gaseous materials in from about 60% to about 95% of the cross-sectional void volume in the insulation, thus incorporating an amount of SF.sub.6 gas in the cross-section of the insulation effective to substantially increase corona inception voltages.

High voltage capability electrical coils insulated with materials

A high power flexible connector has a first conductive member adapted for connection to a bushing and a second conductive member adapted for connection to a winding. A plurality of flexible conductors connect the first member to the second member. Mechanically, the conductors provide for independent movement of the bushing with respect to the winding. Electrically, the cables provide a plurality of current paths and produce an electric field when carrying a current. The conductors are arranged such that the induced electric field is uniform.

Flexible bushing connector

An iron core shunt reactor is constructed of a plurality of foil windings coaxially positioned along an iron core a discrete distance from each other. A coolant circulates axially along the core and radially outward between each of the foil windings providing the shunt reactor with improved thermal characteristics.
