Clamp holder for a supplementary element for high-voltage overhead lines

The invention relates to a clamp holder for supplementary elements in line clamping area of high-voltage overhead lines. The clamp holder comprises a lower clamping member and an upper clamping member, which are made of metals and designed as an integral stamped bent part. The lower clamping member is provided with a substrate and an additional plate, which are connected through bent edges. A seam is arranged in the substrate so that the protruded part of a fixedly holding disc can be inserted into the seam. The additional plate is provided with a plurality of holes for accommodating fixedly held members. The upper clamping member has a main bearing area. The front bent area of the main bearing area is connected to a support. The support has a center area that is connected to the main bearing area. The end portion, which is far away from the main bearing area, of the support is turned into an additional bearing area through a rear bent area. The upper clamping member has at least two holes in the main bearing
