Latest Patents

One of his latest patents is a surge arrester that includes a stack of a plurality of cylindrical varistor blocks arranged in the axial direction between an upper end electrode and a lower end electrode. This innovative design features clamping members made of insulating material, which include at least three loops of continuously wound fiber connecting the electrodes. Additionally, it incorporates a bursting-protective bandage made of fiber rings and a surrounding, electrically insulating outer casing of rubber or other polymeric material. The loops are constructed from glass fiber and exhibit an asymmetrical cross-section.

Another significant patent is a stabilizing device for a transmission line-mounted surge arrester. This line arrester is articulately suspended from a transmission or distribution network, and the stabilizing device increases the mass-moment of inertia of the line arrester. This enhancement helps to minimize movements deviating from the vertical line, ensuring stability during operation.
