The guide rod is especially suitable for the working scene of laying soft cables in cable trenches, dark trenches, etc. It can meet the requirements of rapid construction of short-distance trenches without cover plates, and has obvious advantages in construction in trenches with heavy cover plates. The advantage is that when facing the large cover plate of the cable trench, just lift off the corresponding cover plates at both ends of the screen, and the network cable can be easily and quickly passed from one end to the other end, thus greatly reducing the physical effort of team members during construction. The cable trench cover in the substation is usually heavy in weight and has a large number. Using this guide rod to lay the flexible cable from one end of the trench to the other end can save the need to open the middle cover of the trench (for the middle part of the trench. The advantage of the situation that cannot be opened is particularly obvious), which saves a lot of manpower, and also effectively avoids the risk of crushing and crushing the hands and feet of the construction personnel when opening the cover.

The guide rod of the present invention can be manufactured once and can be used many times, and its multi-section structure is not only convenient to carry, but also can adjust the length, and can adapt to various application scenarios. Since the popularization and use of the guide rod, the workload of laying cables in the substation cable channel of the team members has been effectively reduced, the use of resources such as PVC pipes and insulating tapes has been effectively saved, and the work efficiency has been greatly improved. According to statistical test data, it is found that the work efficiency can be improved by 60% when the cable is laid in the groove that lacks opening conditions in the middle part. Improve work efficiency by about 40%.
