Abstract

Proposed is a multi-layered polytetrafluoroethylene dielectric overcoating for a dicorotron coronode application. Such coating could be applied to a wire conductor made of, for example, tungsten, copper or like metals which may include plating with metals such as silver.

Proposed is a multi-layered polytetrafluoroethylene dielectric overcoating for a dicorotron coronode application. Such coating could be applied to a wire conductor made of, for example, tungsten, copper or like metals which may include plating with metals such as silver.

Currently, the overcoating for dicorotron coronode wires is glass. However, the glass drawing process is complex to operate and difficult to achieve high yields. In addition, the glass drawing process is relatively expensive and very few vendors supply equipment and technical labor for this process.

Polytetrafluoroethylene multi-layer overcoating of dicorotron wires aids in preventing breakdown and/or arcing that would otherwise occur in the case of a single coating operation due to a direct arc path from conductor to shield or other surface.

Proposed is to coat an approximately 4 mil silver plated wire with multiple layers of polytetrafluoroethylene to a thickness of approximately 9 mil.
