Abstract
A separable loadbreak connector system includes mating electrical connectors. At least one of the electrical connectors includes an electrically-resistive housing having a generally conically-shaped interior bore. A semiconductive insert is disposed within a portion of the interior bore and presents an inner radial surface that defines a generally conically-shaped recess. An elongated probe assembly is disposed within the housing and includes a probe and a sheath of insulative material disposed over at least a portion of a length of the probe. A portion of the sheath extends in a radially outward direction from a base of the probe. An electrically-resistive insulative layer extends from the conically-shaped interior bore, along at least a portion of the inner radial surface of the semiconductive insert. The insulative layer extends radially inwardly in overlapping engagement with a portion of the sheath.
