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.
