An active part of the dry transformer comprising a core (1) with yokes (2) and limbs (3) having an a longitudinal axis (A) around which LV coils (4) and winding bobbin (5) is placed concentrically. The bobbin (5) has a shape of a longitudinal cylinder (5a) which is ended with annular discs (5b). The bobbin (5) is made of material having a dielectric permittivity which is two to five times higher more the dielectric permittivity of the insulating body (8) surrounding the limb (3) around the axis (A), in which the LV coils (4) and HV coils (6) are embedded. The external facial surfaces of the insulating body (8) is provided with a metallic layer (10) having such electric conductivity that the part of the insulating body (8) between an internal surface of the metallic layer (10) and an external surface of the annular disc (5b) has a thickness (d3) which is sufficient for insulation. A side surface of the cylinder (5a) is covered with a resistive layer (7) being a control shield of an electric field around the limb (3) of the core (1) and the HV coils (6) and the LV coils (4).

Abstract: The invention relates in general to manufacturing of an improved amorphous metal magnetic core (1) or (1') for electrical inductive apparatus such as transformers and reactors. A method of manufacturing an amorphous magnetic core comprises assembling a plurality of lamination layers (6, 6') made of amorphous metal strips to designing a core shape, having two parallel faces (9) or side surfaces (9') formed by edges of the lamination layers (6,6'). The method further comprises the step of introducing between the neighboring lamination layers (6,6') of the core (1,1') an organometallic binder (11) for receiving a number of film layers (8,8') of the binder. Next the step of binding together the lamination layers with the film layers is used by annealing the core at a temperature 350-400°C and in a magnetic field having value above 800A/m. The lamination layers (6,6') are bonded with the film layers (8,8') have capabilities for audible noise reduction when the core is under operating condition.
