Problems solved by technology

[0002] At present, the stay wires of known non-self-supporting transmission towers are steel cables, which cannot resist compression. When the stay wire or the connection between the stay wire and the tower or the connection between the stay wire and the foundation breaks, the tower may collapse, and even the entire tension section tower collapse

Embodiment Construction

[0009] A steel pipe (4), (5) is respectively set on the guy wires (2) and (3), and the steel pipe (4), (5) is consolidated with the foundation fixing members of the guy wires (2) and (3). There is a gap between the steel pipes (4), (5) and the pole tower (1), and the gap is greater than the maximum allowable elastic displacement of the pole tower (1) there, so as not to change the flexibility of the pole tower (1).

Abstract

The invention relates to a complex pull wire. The feature is adding a steel pipe on the pull wire and there is clearance between the wire and the pipe to make the wire have the function of compression resistant. The steel pipe is fixed with the groundsill firmware of the pull wire. When the connection component between pull wire, or pull wire and perch, or the connection component between pull wire and groundsill is broken, the side direction moving would be stopped by steel pipe. Thus, the possibility of the perch break down would be reduced.

Description

Technical field [0001] The invention relates to a connecting piece between a power transmission tower and a foundation, in particular to a cable for a non-self-supporting power transmission tower. Background technique [0002] At present, the cable of the known non-self-supporting transmission tower is a steel cable, which cannot withstand compression. When the cable or the connection between the cable and the tower or the connection between the cable and the foundation is broken, the tower may collapse, and even the entire tension section The tower collapsed. In August 1988, the accident of the four-base pole tower on the Fanyao line in Anhui, China was exemplified. Summary of the invention [0003] In order to overcome the shortcoming that the existing non-self-supporting power transmission tower’s cable or its connection with the tower or its connection with the foundation may collapse, the present invention provides a composite cable, which can reduce the tension or When the...
