The utility model provides a novel single circuit breaking pole tower and relates to the technical field of high voltage transmission lines. The novel single circuit breaking pole tower comprises a tower body, a ground wire support, an upper wire cross arm, a middle wire cross arm, a lower wire cross arm, a ground wire cross arm and a wire cross arm, wherein the ground wire support, the upper wire cross arm, the middle wire cross arm and the lower wire cross arm are vertical to a circuit direction, the ground wire cross arm and the wire cross arm are parallel to the circuit direction, the ground wire cross arm is arranged below the ground wire support, and the wire cross arm is arranged below the lower wire cross arm. The novel single circuit breaking pole tower solves the problem that a single-circuit target circuit is broken while stress and electric clearance conditions of a pole tower are met, and the defects that a single circuit wire contracts inward, the electric clearance can not meet the requirement, steel consumption and foundation work amount are correspondingly increased and economical performance is poor are overcome.
