Tower for supporting overhead line of extra-high voltage electric power transmission

摘要

The present invention relates to a pylon for supporting an overhead line for extra-high voltage electric power transmission. A cleaning water spray device which is elastically installed is configured to be lifted and horizontally and vertically rotated by a lifting device, a horizontal rotation device, and a vertical rotation device. A worker can clean a suspension insulator by a remote control. A cleaning water spray nozzle and a cleaning water supply hose, etc. are not exposed to wind and rain at normal times, thereby always maintaining an operable state without blocking the cleaning water spray nozzle and damaging the cleaning water supply hose. If the maintenance and repair of a cleaning water spray tube are required, an operation can be safely performed on the ground without an electric shock accident and a falling accident.
