The single-wire transformer for gas or liquid insulated high voltage switchgear has the single wire passing through a metal tube (4) which has a metal disc (10) attached to its outside, top and bottom, for support from ring- shaped flanges (11) also at top and bottom of the encapsulating tube (1) around the outside. The bottom supporting disc (10) which carries sets of windings (15, 16, 17) each around an iron core (12, 13, 14) has a resilient washer under the bottom coil (17) and further resilient washers (19, 20) between the coils. These coils are attached to the inside tube (4) by an adhesive cast resin which is poured in while liquid and allowed to set. In an alternative method, adhesive strips are inserted between the tube and the coils. |
