The utility model discloses an anti-static safe rubber tube special for high-pressure steam. A supporting layer, an inner rubber layer, an inner framework layer, a middle rubber layer, an outer framework layer, an outer rubber layer and an outer conducting layer are sequentially arranged from inside to outside. The supporting layer comprises a plurality of supporting blocks and a plurality of connecting blocks which are alternately arranged in the circumferential direction. Clamping grooves are formed in the two sides of the supporting block. Clamping blocks which are embedded into the clamping grooves in an interference manner are arranged on the two sides of the connecting block; grooves are formed in the sides, away from the inner rubber layer, of the supporting blocks in the length direction; the connecting blocks are made of conductive rubber materials, a plurality of conductive columns are evenly distributed on the side, close to the inner rubber layer, of each connecting block in the length direction,
