Cable end closure for e.g. outdoor application for high-voltage energy cable, has closure units formed such that parts of closure are not detached during exceedance of inner pressure in uncontrolled manner

摘要

The closure (10) has lockable pressure discharge openings (36.1, 58) formed for an insulation medium, which forms an opening during exceedance of predetermined inner pressure. The pressure discharge openings are formed in a plate (52) in a bottom fitting (50) and/or in a plate (32) in a top fitting (30). The two plates are extensively penetrated by the pressure discharge openings. Closure units closing the pressure discharge openings are formed such that parts of the closure are not detached during exceedance of the inner pressure in an uncontrolled manner.
