spacer field damper for farmers in bundle of electrical lines

摘要

Spacer-damper for a bundled conductor of an electric line comprising a support (1) bearing joints (2) for the arms (3) that hold the sub-conductors wherein each joint (2) is composed by at least one frame (5) integral with or fixed to the support (1), by a core (6) positioned within the frame (5), by a plurality of elastic elements (7) for each frame (5), each elastic element (7) being fixed by one end to the relevant frame (5) and by the other end to the relevant core (6) as well as by an arm (3) which bears at one end a clamp for clamping a sub conductor and which is fixed by the other end to a core (6) or to cores for the core or cores being allowed to move elastically within the frame (5) or the frames under the actions that the relevant sub-conductor transmit to the arm.
