0.4 kV line phase-to-phase anti-collision device

The invention discloses a 0.4 kV line phase-to-phase anti-collision device. The anti-collision device comprises a rotating unit, a bearing unit, an adjusting unit and a limiting unit, the rotating unit comprises a first rotating shaft and first limiting blocks connected to the two ends of the first rotating shaft in a sleeving mode, the bearing unit is fixedly connected with the rotating unit through the first limiting blocks, and the adjusting unit is in shaft connection with the bearing unit through a bearing; and the limiting unit is fixedly connected with the inner wall of the first limiting block through a first fixing block. The rotating unit, the bearing unit, the adjusting unit and the limiting unit are matched with one another, so that a circuit is separated, the situation that wires with lower sag are wound together under the effect of wind power and external force due to overlarge sag of the circuit is avoided, the situations of short circuit of a low-voltage circuit, voltage rise and burnout of us
