More Information
Summary:A switchgear system operable at voltages up to 27 kV includes an enclosure containing atmospheric air and a loadbreak module disposed within the enclosure. The loadbreak module includes a loadbreak module housing made of a solid dielectric material, a vacuum interrupter enclosed within the loadbreak module housing and having a fixed contact and a movable contact, and an interchange electrically connected to the movable contact. The vacuum interrupter is operable to selectively break or establish an electrical pathway between the interchange and a terminal in response to movement of the movable contact relative to the fixed contact. The switchgear system further includes a bushing coupled to the enclosure and a disconnect switch electrically connected in series between the loadbreak module and the bushing. The disconnect switch includes a disconnect switch housing made of a solid dielectric material.
