ABSTRACT:
A high voltage transformer includes at least one secondary coil mounted on an insulating support assembly and having the start lead of the secondary coil disposed proximate to the transformer core with a finish lead disposed at the perimeter of the coil. The finish lead is connected to ground potential and the start lead is provided at the high voltage potential of the transformer, thereby minimizing the insulation requirements of the transformer. The insulating support assembly for the secondary coil includes flanges at the opposite ends thereof to define a winding space for the secondary coil. Each of the flanges includes a channel formed therein for providing a passageway for the high voltage start lead of the secondary coil that extends from the inside layer of the secondary coil to above the edge of the flange. The flange also has a recess that extends between the opposite edges thereof for receiving and insulating sheet member.
