The invention discloses a power tower. The power tower comprises a power tower main body and a foundation, wherein four support frames are uniformly welded around the bottom end of the power tower main body, positioning columns are fixedly mounted at the bottom ends of the support frames through bolts, a control box is arranged at the middle parts of the support frames, an operation box is arranged at the middle parts of the bottom ends of the support frames, and fixed sleeve assemblies corresponding to the support frames are vertically arranged around the foundation uniformly. The power towerdisclosed by the invention has the advantages that power transmission lines with different voltages are erected on a first bobbin, a second bobbin and a third bobbin, thereby bringing safety and convenience; a driving motor in the operation box controls a sliding board to ascend or descend by matching of a rack and a gear, thereby being favorable for realizing rapid maintenance; an electric leakage protector is matched with an arc-control device, thereby being favorable for avoiding electric shock of maintenance personnel and personnel near the power tower main body; and the fixed sleeve assemblies are used, thereby saving the cultivated area and enhancing the stability of the power tower main body.
