Abstract: A high voltage electrical resistor comprises a resistive path supported on a dielectric hollow cylindrical substrate, termination means electrically connected to the resistive path, an insulation system and a heat dissipation system. The high voltage end of the substrate is spaced from the wall of an insulative jacket by means of projections extending radially inwardly from the wall. The low voltage end of the substrate is spaced from the wall of the jacket by means of a heat dissipating mounting member. The termination means include insulated lead wires electrically connected to the resistive path with a lead wire adjacent the high voltage end of the substrate passing through a tubular projection of the jacket. A heat shrunk sleeve forms a tight seal between the tubular projection and the lead wire. Dielectric material fills the space between the substrate and the jacket forming a moisture impervious barrier around the resistive path and improving the dielectric strength of the resistor.
