FIELD: machine building.SUBSTANCE: supporting bracket (1) is designed for supporting of insulating rods (2) inside an insulating tube (3) of a hollow insulator. The bracket (1) comprises a cylindrical ring (4) with outer surface (5) for adjoining the inner surface (6) of the insulating tube (3), with inner surface (7) for supporting of insulating rod and two opposite end sides (8a) and (8b). The bracket (1) comprises an extension unit including a block made so that to be able of actuation in order to extend the cylindrical ring in at least one radial direction at the installation of the supporting bracket (1) into the insulating tube of a tank's active circuit breaker.EFFECT: improved manufacturability of supporting bracket due to mechanical coupling inside an insulating tube.14 cl, 9 dwg |
