The invention, which relates to the technical field of power transmission and transformation, provides a 10-kV power transmission and interruption device comprising an outer tube. A lower rotating sleeve is arranged at the lower side of the outer tube; a connection sleeve is arranged at the upper side of the outer tube; a vertical upper tube is installed at the connection sleeve; an upper rotatingbox is arranged at the upper end portion of the upper tube; and a cross bar is arranged at one side of the upper tube. A shape adjusting mechanism is arranged in the upper rotating box; and a limiting mechanism is arranged inside a lower rotating sleeve. According to the invention, the 10-kV power transmission and interruption device is used for power transmission without manual power transmission, so that the work accuracy and efficiency are improved, the high safety and reliability are realized, and the safety factor is improved; and with the shape adjusting mechanism, an inner extrusion film is in contact with a rotary button to avoid idling of the rotary button.
