Abstract

1. Method of producing a vacuum-sealed and oil-tight closure for transformer construction, in which a shield electrode (9) is provided with an insulating retaining element (10) which is produced using transformer board, characterised by the following steps : a) at least in the main part of its length the shield electrode (9) is shaped around with a first layer of insulating material (11) made from transformer board ; b) then a second layer of insulating material (12) which corresponds to the desired shape of the retaining element (10) and is made from transformer board is applied so that it partially overlaps the first layer of insulating material (11) ; c) after vacuum drying the two layers of insulating material (11, 12) made from transformer board are impregnated in a vacuum with an oil-resistant resin of low or medium viscosity which hardens at low temperature ; d) after the resin has hardened, the film formed by the two layers of impregnated insulating material (11, 12) is provided on each of the free outer faces with at least one further layer of insulating material (14, 15, 16).
