Fibre reinforced insulation material for embedded vacuum interrupters

摘要

The present invention is concerned with the embedding of vacuum interrupters, in particular with a vacuum interrupter (300) embedded in an insulating material (301), the insulating material (301) comprising a first main layer (100) having a first sub-layer (101), a second sub-layer (102), and a third sub-layer (103). The second sub-layer (102) is arranged between the first sub-layer (101) and the third sub-layer (103). The first sub-layer (101), the second sub-layer (102), and the third sub-layer (103) comprise fibres, wherein the first sub-layer (101) comprises a group of first fibres (110) which are arranged in parallel with respect to each other.
