ABSTRACT OF THE DISCLOSURE A relatively-small-diameter conductive cylindri- cal tubing, or metallic rod element is wound helically in the shape of the desired electrostatic metallic shield element. The turns of the metallic coil, thus formed, may be cemented, soldered, welded or otherwise fastened to- gether to thereby provide rigidity to the metallic shield, if desired. The turns of the metallic coil may, however, be separated from one another by a space. One or both ends of the coil may be bent transversely away from the shield's surface for use both as a physical support during casting, or encapsulation, and, alternatively, as conducting leads for grounding purposes, or for terminal connection purposes. The body portion of the insulating member may be composed of any suitable casting material, such as resinous material, either epoxy resin, or polyester resin, or Butyl rubber. The insulating body may either be a spacer for spacing a high-voltage power-conductor member within an outer grounded piping system in gas-insulated power trans- mission equipment, for example, or, alternatively, the in- sulating member may be a somewhat conventional-type term- inal-bushing body portion, providing an insulated con- ductor-lead into suitable electrical equipment, such as circuit-breaker equipment, current-transformer equipment, potential-transformer equipment, or like electrical appara- tus, for example.
