One end cap is electrically connected to a fixed contact, while an opposing end cap is connected to a moving contact. The moving contact is actuatable with the fixed contact for opening or closing an electric circuit. A floating shield inside the vacuum chamber connected to the vacuum chamber ceramic wall and spaced from the fixed and moving contacts is isolated and has a floating voltage potential. A portion of the vacuum chamber exterior ceramic wall is coated with a semi-conductive material and conductive voltage screens enclose a portion of the vacuum chamber exterior and are electrically connected to each conductive end cap of the vacuum chamber. The chamber and connected screens are encapsulated in a molded dielectric housing.

摘要： An integrated outdoor terminal is disclosed that reduces the effects of environmental and electrical stresses by integrating a first portion, second portion and plurality of sheds into a one-piece insulation body. The first portion includes an integrated first connector for connecting the outdoor terminal to a high voltage cable. The second portion functions as a stress cone and connects with a second terminal for connecting with ground. The first portion has a generally cylindrical shape and the stress cone has a generally conical shape. The first portion transitions into the second portion without any abrupt changes in cross-sectional area, thus avoiding an increase in electric fields. The integrated outdoor termination may be prefabricated using a material such as silicone. The sheds extend approximately perpendicular to and may be uniformly distributed along the longitudinal axis of the insulation body. By uniformly distributing the sheds, the risk of flashover is avoided.
