ABSTRACT:
A conformable layer (14) for inhibiting electrical discharge between vent tubes (16) and strands (12) in an inner-cooled coil (5). The conformable layer comprises a resistive inner core (24) and a conductive strip (20) wrapped in a conductive outer wrap (26). The conductive strip (20) is electrically connected to the strands (12) at one end of the coil (5) and left to electrically float at the other end. In this configuration, the conformable layer (14) reduces voltage buildup between the vent tubes (16) and the strands (12) to help prevent electrical damage to the coil (5).
