Compared with the prior art, the invention has the following beneficial effects: the upper, middle and lower three layers of cantilever beams of the vertical wire outlet tower are staggered up and down to form a 'rice' -shaped arrangement, so that three-phase wires are vertically arranged in space, and the effect of compressing the width of the wire outlet framework is achieved by utilizing the space arrangement mode of the wires. The two-circuit outgoing lines share the vertical outgoing line tower, the wire vertical arrangement mode is utilized, the wire outlet interval width can be effectively compressed, the occupied area of the transformer substation is saved, the steel consumption of the framework is reduced, the framework steel and civil engineering foundation investment are saved, meanwhile, the wiring of the two-circuit outgoing line tower can be matched with the wiring of the line side terminal tower better, and the line side design is more beneficial.
