During the routine maintenance of a section of the contact network of the Beijing-Shanghai High-Speed Railway, engineers found a batch of special "small objects" that were more than 10 years old - plastic cable ties. These seemingly ordinary white straps of plastic cable ties are still firmly fixed after long-term exposure to wind, sun, rain and snow, and their insulation performance and mechanical strength have not weakened. This discovery amazed the on-site technicians.

Metal cable ties and plastic ties have different advantages. Therefore, in some complex usage scenarios, a single material binding wire may not meet all needs, but the combination of the two may become an ideal solution. The combined use of these two materials not only provides a new solution for the project, but also further improves the safety of the power system.
