In this embodiment, the wire hanging portion 342 is a hanging ring structure, and in other embodiments, the wire hanging portion 342 may also be other structures such as a wire binding groove, which is not limited herein.

Further, in this embodiment, the tower body 310 is a door-shaped structure, and includes two steel pipe poles 310, and the two steel pipe poles 310 and the cross arm 320 are both fixedly connected through the hoop assembly 341. Cross arm 320 still includes insulating layer 321, and the material and the shaping mode of insulating layer 321 are unanimous with the first insulating layer in the second embodiment, and no longer give unnecessary details, and specifically, insulating layer 321 includes sheath 3211 and full skirt 3212, and sheath 3211 cladding is in the periphery of core, and full skirt 3212 sets up in the periphery of sheath 3211 with the combination interval of big umbrella, and does not set up full skirt 3212 outside the sheath 3211 of staple bolt subassembly 341 and cross arm 320 junction to form the connection space.

The beneficial effects of the emergency repair tower 30 of this embodiment are similar to those of the second embodiment, and are not described again. Meanwhile, the rush-repair tower 30 is provided with the wire hanging fitting 330 at the end of the cross arm 320, so that a supporting part is not required to be additionally arranged to support the transmission conductor, the number of the whole parts of the rush-repair tower 30 is reduced, the weight of the rush-repair tower 30 is reduced, the cost is reduced, and the transmission and installation are facilitated, so that the rush-repair time is shortened. In other embodiments, the cross arm 320 may also adopt the composite cross beam structure in embodiment two, which is not described herein again.
