The utility model provides a whole steel pipe transmission line framework for an ultra-high voltage AC (alternating current) transmission line, which comprises a framework column structure and a framework beam structure supported by the framework column structure. Compared with the prior art, the transmission line framework adopting a steel pipe structure has higher bearing capacity, and can satisfy the deformation requirement of the ultra-high voltage transmission line on the transmission line structure. In a preferential implementation way, a plurality of column cross-sections are arranged on a framework column of the transmission line structure at intervals, and the column cross-section structure can improve the stability of the whole transmission line framework by improving the stability of the framework column.
