Insulating system for medium high-voltage (HV) installations has an electrical functional unit with HV and earth connections and field control elements to influence electrical fields

摘要

An electrical functional unit (EFU) (2) has a high-voltage connection (4) and an earth connection (3). Field control elements (FCE) (5,6) fit around the EFU and influence the electrical field around the EFU, which is cast in insulating material (9,13) along with the FCE. All these produce an electrical field that is as homogenous as possible and that can be produced with particular benefit. An independent claim is also included for a method for producing an insulating system for medium high voltage installations.
