The utility model discloses a slippage-resistance jumper-wire tubular-bus structure used for a +- 800kV ultra-high-voltage DC line. The structure includes mutually connected tubular-bus wires and a tubular-bus outer joint is sleeved outside the mutually connected tubular-bus wires. The tubular-bus outer joint is fixedly connected through a plurality of groups of screws and nuts. The structure is provided with a reinforcing part. The reinforcing part is provided with an inner joint which has a tubular structure and matches the tubular-bus wires. The tubular-bus wires are sleeved at the outer side of the inner joint. The inner joint is provides with a block table which protrudes for a ring. The mutually connected tubular-bus wires are arranged at the two sides of the block table. Screw wholes are arranged at positions of the tubular-bus wires, corresponding to the inner joint and fixing screws are arranged in the screw holes. The slippage-resistance jumper-wire tubular-bus structure used for the +- 800kV ultra-high-voltage DC line enables the tubular-bus wires to be connected and fixed with the inner joint of the reinforcing part through the fixing screws and the tubular-bus outer joint to be sleeved at the outer sides of the tubular-bus wires so that the tubular-bus structure is more stable and less likely to fall off.
