More Information
Summary:A live-line changing method of a damaged spacer damper for 765kV double circuit transmission lines is provided to maintain and repair the 765kV double circuit transmission lines without a stoppage of power supply by changing the damaged spacer damper safely. A pylon arm worktable(11), a polymer insulator(12), a live-line workable(13), multipurpose insulating ropes(15,16), a space car, and a fixing apparatus are used for changing a damaged spacer damper in a live-line state. The pylon worktable detaches a ground side arching horn and a socket clevis and connects and disconnects an insulator string pulling insulating rope. The polymer insulator insulates and supports a worker. The live-line worktable moves the worker. The space car moves on an electric line. The fixing apparatus prevents drooping of the insulating ropes.
