A support bracket for supporting insulating rods inside an insulator tube of a hollow core insulator. The support bracket includes a cylindrical ring with an outer surface for abutting against the inner surface of an insulator tube, an inner surface for supporting an insulating rod and two opposing end sides, denominated by first and second end sides. The support bracket includes an expansion assembly configured to be actuated so as to expand the cylindrical ring in at least one radial direction when the support bracket has been inserted in an insulator tube of a live tank circuit breaker.

Support bracket

A method and apparatus for manufacturing fiber-reinforced products with integrated insert parts by moulding a heat-bonding resin having a viscosity of about 1-10_6 and about 30-10+6 mPas, between two joinable halves of a separable mould having an upper and lower mould parts forming a cavity therebetween, the inner moulding faces are attached to displaceable fixed parts of a pressing table. Prior to moulding, an insert part is fixed in position in the cavity, and the mould parts each have a set of a support devices displaceable in the cavity relative to the respective moulding faces. According to the method, the resin is located in the cavity before the mold is closes and the insert is in position prior to and during an initial phase of moulding. The support device is removed prior to the setting of the resin in the mould leaving holes in the material, and thereafter the mold parts are held together for filling the holes.
