The invention proposes a 110KV two-circuit T-joint steel pipe pole. The 110KV two-circuit T-joint steel pipe pole comprises a main pole, a main line cross arm and a T-joint cross arm. The main line cross arm and the T-joint cross arm are mounted on the main pole and the T-joint cross arm and the main line cross arm are arranged in layers on space to form an included angle. When two-circuit lines are switched in from one side of the main line cross arm, the two-circuit lines are switched out from the main line cross arm and the other side opposite to the side. The 110KV two-circuit T-joint steel pipe pole better fulfils the requirements on clearance of a tower body by the wires, optimizes the size of the cross arm, has a clear power transmission line and more rational stress, solves the problems that the floor area is large and the quantity of tower materials and basic materials is large in the traditional T-joint angle bar tray, and effectively saves energy.
