Abstract: A suspension device for a line arrester in an air-insulated transmission line including two suspension parts which support the line arrester such that its longitudinal axis deviates from the vertical line. One of the suspension parts includes a disconnecting device which, when releasing, permits the line arrester a swinging motion under the influence of a force of gravity caused by the weight of the line arrester itself. And, one of the suspension parts includes a damping member which influences the line arrester with a force directed against the swinging motion during at least part of the swinging motion. The damping member may include a damping plate, one or more friction linings, or a flexible wire.

Abstract: The invention relates to a surge arrester assembly with a plurality of parallel-connected arrester units (1) with polymer casing mounted in a rack. The lower and upper parts of the rack consist of bars (4a, 4b) of, for example, aluminium, which are included in the electric circuit. The bars are retained by, for example, support insulators (6) of porcelain or polymer material. The mechanical retention of the stacks of ZnO blocks of the arrester units (1) and the necessary contact pressure between the blocks are ensured by the rack structure. The electrical connections (23, 24) to the rack are arranged in such a way that, if a fault causing a short circuit in one of the block stacks occurs, the arc produced is blown by the current forces along the bars to the opposite end, where arcing horns (38) of a current-resistant material, for example steel, are arranged and where the arc may burn in a controlled manner without involving a risk to the environment. (FIG. 1 )
