Overmolded electrical device with low electrical stress parting lines

Abstract

An electrical device includes an internal electrical conductor that extends along a longitudinal axis. An insulator is overmolded around the internal electrical conductor such that the insulator includes first and second insulator portions with a parting plane at an interface between the first and second insulator portions. The parting plane is oriented such that it intersects the longitudinal axis. The electrical device may include a low electrical stress area defined by an electrical shield, wherein the parting line may be disposed entirely within the low electrical stress area. The electrical device may be a switchgear that includes a vacuum interrupter assembly having a vacuum bottle surrounded by an insulating sleeve comprising first and second sleeve portions with a parting plane at an interface between the first and second sleeve portions. The parting plane is oriented such that it intersects the longitudinal axis.
