The utility model relates to the technical field of power transmission line facility, in particular to a light line repair tower. As 10Kv and 35Kv power transmission and distribution lines in distribution network are distributed widely, accidents such as pole falling and the like severely affects normal power supply of the electric network. The existing repair mode has the shortages that time of power failure and repairing is longer because normal poles and towers are larger in volume, heavier in weight and then inconvenient in transport. The light line repair tower consists of a base plate, a tower body, a cross arm and a supporting device, the tower body consists of an upper section, an intermediate section, a lower section, a cross section and a pull wire, the upper section of the tower body is conical, the cross section is respectively connected with a lower end face of the upper section and the upper end face of the intermediate section, the lower end face of the intermediate section is connected with the upper end face of the lower section or the upper end face of another intermediate section, the lower section of the tower body is connected with the base plate, and the cross arm is connected with the cross section. The light line repair tower is simple and reasonable in structure and convenient in transportation, can be assembled on site, handles accidents of fallen poles and broken wires fast, improves line repair work efficiency, and shortens power failure time due to line fault.
