Abstract

The invention discloses a double-loop composite tower head pole tower, and belongs to the technical field of pole towers for power transmission lines. The double-loop composite tower head pole tower comprises a composite tower head and a steel tower body. A structure combining a composite and common steel is adopted, on one hand, the insulation property of the composite of the tower head is utilized, pollution flashover accidents of the power transmission lines are reduced, and the safe operation level of the lines is improved; and the size of the tower head is reduced, the width of a power transmission channel corridor is greatly reduced, land occupation is reduced, and precious land resources are saved. On the other hand, due to the fact that the elasticity modulus of the composite is lower than that of the steel, the overall stability problem is prominent, a large section needs to be selected for main stress components on the lower portion of the tower body, the characteristics of the steel can be fully utilized by selecting the steel, materials are saved, and the overall manufacturing cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of towers for power transmission lines, and in particular relates to a double-circuit composite material tower head. Background technique [0002] The transmission line tower structure is the supporting structure in the power overhead transmission line facilities. With the development of my country's power grid, the transmission line project presents a long-distance, large-scale, and large-scale development trend. At present, a large amount of steel is used in transmission line poles and towers, and the demand for steel is increasing year by year, consuming a large amount of mineral resources and causing pollution to the ecological environment. At the same time, a large number of steel materials are used as iron tower materials, which also brings many difficulties to the construction, transportation and operation and maintenance of the tower. [0003] Therefore need to propose a kind of new transmission lin...
