Abstract
A bushing insulator to be applied between an electrical conductor and a tank of a transformer or another equivalent body, of the type for low voltages (1 to 3 kV and currents from 100 to 6500 A), comprising a part (19) to be exposed to the air which is coupled to a part (29) to be arranged inside the tank; the parts are crossed axially by a tie (15) which acts as an electrical conductor, the part to be exposed to the air comprising, packed on the tie, a hood (22), an annular gasket (23), an external insulating body (24) and a gasket (28) to be arranged between the insulating body and the tank of the transformer at an opening (14) provided therein; the part (29) to be arranged inside the ta c nk comprising an internal insulating body (30) which engages between the external insulating body (24) and a part which is rigidly coupled to the tie; the hood and each one of the external and internal insulating bodies being made of plastics. <IMAGE>
