Abstract

See full text

A compact device for absorbing kinetic energy generated by, for example, broken electric power lines on electric power transmission towers. The device consists of a non-spring helix, or in or out of plane flat coils that are placed between an electric transmission tower and the conductor insulator. The device deforms by plastically uncoiling in response to forces greater than a predetermined force. The device is a single-event device, designed to be replaced after one extraordinary dynamic event. The device can also be used in other structures or machinery requiring compact long stroke energy absorption.
