Abstract: A tensioning device is provided for a surge arrester having an end fitting and tensioner. The tensioning device has an axial clearance for receiving a tensioner and a region being conically tapered in axial direction to be introduced into a clearance of the end fitting being shaped for a substantially exact fit. The conically tapered region has delimitation walls defining the axial clearance for the tensioner being movable toward a clearance interior. An antifriction layer is applied to the surface of the conically tapered region. A production method for a surge arrester and a corresponding surge arrester are also provided.

Abstract: A rotor for a thermal turbomachine, in particular a gas turbine, designed to conduct a medium, such as compressor air, in the interior of the rotor. In order to conduct the medium in the interior with low flow losses and at the same time to specify a rotor that can be produced comparatively simply and economically, a separately produced blade wheel is arranged between the mutually adjacent hub regions of the two rotor disks, and a sleeve is provided for fastening the blade wheel to one of the two rotor disks, which sleeve extends through the central opening of the one rotor disk and includes a collar serving as a stop at a first end of the sleeve and includes a second end opposite the first end, on which second end the blade wheel is fastened.

Abstract: A surge arrester has a tube-shaped housing, an end fitting connected to an end of the housing, a varistor block arranged in the housing and a supporting element arranged in the region of the end fitting. The supporting element has a supporting ring which is in contact with the housing and which includes a cone and a clamping ring with a counter-cone that corresponds to the cone. The cone is braced to the counter-cone in such a manner that the supporting ring is pressed to the housing in a non-displaceable manner. The supporting element can thus also be used after the installation of the varistor block and also be removed.
