The utility model relates to a high -voltage electric operating technical field, in particular to high voltage steel tube shaft tower earth potential live working folding platform, include: a plurality of fixed bands, riser and landing slab, riser and landing slab are articulated, and the fixed band distributes on landing slab and riser, the riser passes through fixed band and the steel pipe shafttower main part of vertical orientation and is connected fixedly, and the landing slab passes through the fixed band and is connected with the cross arm and fixes, the landing slab is multistage folded cascade structure to the cross arm that adapts to different length. Through the utility model discloses the platform is folded to the multistage formula, the cross arm of steel pipe pole is bindedwith the fixed band and on, the station planes that has enlarged operator person is long -pending, can develop earth potential live working safely, has solved in the past the steel pipe pole because of the narrow problem of hardly developing earth potential live working of cross arm.
