Abstract (en)
[origin: EP2372725A1] This invention relates to a method (100) for manufacturing an electrical insulator for medium or high voltage equipment. The method (100) comprises the steps of forcing all liquid components of an insulating material of the electric insulator through a static mixture (101); adding at least one filler to the components (102); forcing the components with the at least one filler through a tube comprising a fast-turning screw mixing device mixing the components with the at least one filler to a final mixture of the insulating material (103); leading the final mixture to a mould, for example of a hot press, or a mould for vacuum casting, the mould being located in a vacuum chamber the inlet of the vacuum chamber connected to an outlet of the mixing device that is fluidly connected to the mould (104a, 104b); forming an electrical insulator by at least partly curing the final mixture (105); and moulding the electrical insulator (106). The curing may be part of the moulding.
