Fuse element

摘要

A fuse element (10) and a method for manufacturing the same, are provided whereby the fuse element (10) consists of an active response part which is advantageously formed by at least four metal sub-strips (9) of an elongated fuse metal foil with at least respectively two metal sub-strips being parallel being provided by at least two elongated recess within one or two self-supporting elongated fuse metal strips, with the at least two recesses being provides in serial alignment along the respective fuse metal strip, including leading and trailing parts for electrical connection of each fuse element (10), the elongated fuse metal foil can be reinforced by an elongated dielectric base layer made of polymer material. Accordingly, performance of such a fuse element (10) can be increased and manufacturing costs can be decreased. The invention especially can be applied to a plurality of capacitor sub-units being integrated in housings and submerged in a cooling and insulating liquid within the housing.
