Description

Technical Field

[0001] The utility model relates to the technical field of cable installation, in particular to a cable installation structure for municipal engineering. Background Art

[0002] A cable is made of one or more mutually insulated conductors and an outer insulating protective layer. It is a wire that transmits electricity or information from one place to another. It is usually a rope-like cable made of several or several groups of conductors (at least two in each group). Each group of conductors is insulated from each other and often twisted around a center. The entire outside is covered with a highly insulating covering. The cable has the characteristics of internal power conduction and external insulation.

[0003] During the use of cables, due to seasonal changes, hot and cold temperatures will affect the normal use of cables. In actual use, existing cable brackets only provide a limit fixation function for cables. In hot weather, cables may be stretched by heat, and in cold weather, cables may be tightened by cold. At this time, the cables should be adjusted to a certain degree of tightness to avoid damage to the cables caused by weather, but existing cable brackets cannot achieve the above functions.
