Description

Technical Field

[0001] The utility model relates to the technical field of electric power engineering construction, in particular to a cable bridge for electric power engineering construction. Background Art

[0002] Cable trays are commonly used supporting and protecting devices for cable laying in the power supply system of electrical equipment. They protect and guide the cables laid in the cable trays. If cable trays are not used, when the cables are overhead, both ends of the cables will be subjected to very large tensile forces, while the middle part of the cables will be subjected to sagging forces. In order to ensure that the cables are evenly stressed and can work stably for a long time, cable trays must be used to disperse the various forces on the cables and ensure that the cables are safe and reliable.

[0003] In the process of laying power cables on cable trays, the existing cable trays have a simple internal structure, which easily causes the lines to be tangled and disordered, making it inconvenient to sort out and repair. In addition, during the use of the cables, the cable trays have poor heat dissipation, causing the stacked cables to be in a state of heat accumulation for a long time, which will affect the life of the cables.
