To meet the current needs of people's daily travel and normal life and work, urban traffic must To provide convenient and fast services extending in all directions, urban rail transit is the main measure to improve the traffic environment in major international cities. my country's large and medium-sized cities learn from foreign experience, and the construction of rapid rail transit is in the ascendant. At present, many cities such as Beijing, Shanghai, Tianjin, Chongqing, Dalian and Guangzhou are building or continuing to build subway light rail. The rail transit line provides a lot of convenience for everyone's life and work, and also improves efficiency to meet people's efficient and fast work. The needs of the pace of life. The development of urban rail transit also provides business opportunities for the cable industry. However, due to the particularity of the cable laying environment for rail transit: in the densely populated, especially humid and antsy southern regions, the existing rails are more common DC cables. Generally, ethylene-propylene rubber is used as the insulating material, and the insulated wire core is wrapped with low-smoke, halogen-free and flame-retardant tape, longitudinally wrapped with aluminum-plastic composite tape, and the outer sheath is extruded to prevent rodents, termites, and low-smoke, halogen-free, and flame-retardant sheath material structure. , so that the cable has a certain performance of waterproof, flame retardant, low-smoke and halogen-free, rodent-proof and termite-proof, but with the development of subways and light rails, the performance requirements of products are getting higher and higher, especially when laying in narrow spaces and laying Products in harsh environments with strong vibrations, products with existing structures can no longer meet these comprehensive environments.
