A method of reinforcing the solid round leg in existing telecom towers (Guyed & Self-Support), it increases the leg resistance in compression (bearing load) over 50%. This type of reinforcing uses the principal and definition of axial force in truss structure by keeping the center of gravity of the new reinforcing members in the same location of the existing solid round leg. This type of reinforcing uses the existing splice pads as a foundation and a platform to build the new reinforcing structure on it. The new reinforcing structure is a replacement of the existing bolting system with new threaded bars and couplers with high strength. The addition of the new threaded bars benefits the overstressed leg, by adding more cross-sectional area to the original solid round leg section.

An apparatus for damping vibrations in high-voltage devices has a support arrangement for the high-voltage device. The support arrangement includes support elements interconnected by connection elements. Intermediate elements, in particular coated washers, are arranged between the connection elements and the support elements and/or between different support elements. There is also described a method for damping vibrations, in which connection elements spatially fix support elements of the support arrangement of a high-voltage device in a mechanically stable manner. When mechanical vibrations occur on the high-voltage device, the connection elements dampen the mechanical vibration in a defined manner via a predetermined sliding friction with the support elements and via a spatially predetermined play in relation to the support elements.
