Cross-linked cablesCross-linked cables are a special type of cable whose insulation is made of cross-linked polyethylene (XLPE). Compared with traditional polyvinyl chloride (PVC) insulated cables, cross-linked cables have higher heat resistance, stronger electrical properties, and longer service life. These advantages make cross-linked cables widely used in many fields, such as power systems, industrial automation, urban rail transit, etc.
The production process of cross-linked cable is relatively complex and needs to go through multiple processes and links. First, the conductor core needs to be twisted into a cable core on a stranding machine, and then it goes through processes such as filling, tapering, extrusion, and finally cross-linking at high temperatures. In this process, the thickness and uniformity of the insulation layer are the key factors affecting the performance of the cable, so the control of temperature, pressure and time during the production process is crucial.
Because the insulating material of the cross-linked cable has excellent electrical properties and heat resistance, its electrical properties and heat resistance are also relatively high. In addition, the cross-linked cable also has high mechanical strength and corrosion resistance, and can work stably for a long time in various complex environments. These advantages make cross-linked cables the preferred material for power systems, as well as important equipment materials for industrial automation and urban rail transit.
However, there are some drawbacks to cross-linked cables. For example, the production process is complex, costly, and requires high installation and maintenance. Therefore, when choosing to use cross-linked cables, there are trade-offs that need to be made based on actual needs and cost considerations.
In conclusion, cross-linked cable is a cable material with excellent properties and has been widely used in many fields. With the continuous progress of technology and the continuous improvement of application requirements, the performance and application range of cross-linked cables will continue to expand.
