1. There is a problem. Separate structures for power, control, data signals and safety protection lines; B. New energy cables have poor low-frequency conduction, high-frequency conduction and radiation interference functions; C. Poor insulation performance; D. Cables are environmentally friendly, resistant to high and low temperatures, and poor in oil resistance. 2. The following technical solutions are used to solve technical problems: A. The new structure cable structure adopts power cables, control cables, data signal cables and safety protection lines. Solved the problem of the original single core. After the new energy cable core is cabled, it is braided and shielded with copper wire or tinned copper wire. The diameter of monofilament is 0.15mm, and the weaving density is not less than 80%. Then wrap the aluminum-plastic composite tape on the outside for shielding, and the aluminum-plastic composite tape is less than 15%. During the trial production process, we followed up to ensure that the weaving layer is tight and the aluminum-plastic composite tape coverage. Effectively avoid low-frequency conduction, high-frequency conduction and radiation interference. C. Copper core soft conductor is used to improve the cable performance and make the cable have good flexibility. The insulation of this product is made of thermoplastic compound vulcanized rubber tpv material, and the sheath material is made of 125 ℃ low-smoke halogen-free flame-retardant thermoplastic polyurethane elastomer tpu material. Safe use of cables in the presence of flammable gases. The shielding layer of the cable is in the form of copper braided shielding, which ensures the safe use of the cable in high temperature and chemical corrosion environments. Low-smoke, halogen-free flame-retardant materials are used for the auxiliary material filling layer and tape layer of the cable, which ensures the flame-retardant and environmental performance of the cable. 3. During the research and production process of the sheath production process, the material is very sensitive to the temperature of the extruder body. High and low temperature will cause poor surface quality or poor plasticization of the extruded sheath, which will affect the appearance and physical and mechanical properties of the cable. During the production process, because the molecules of the material contain ether bonds, it is easy to absorb water, and the water content is very high, and it is easy to generate a lot of air bubbles when it is squeezed, so it cannot be used. Therefore, we have properly pre-dried the material before extrusion, by optimizing the temperature distribution of the extruder, setting the body temperature reasonably, and finally determining the equipment parameters in actual production, improving the extrusion quality, and making the cable sheath The surface is smooth, round and fully plasticized to the expected physical properties. 4. The outstanding innovation of this new energy cable. A. New structure: The cable structure adopts power cables, control cables, data signal cables and safety protection lines. By studying the structure and use of power, control, data signal and safety protection wires of locomotive cables, a design structure integrating power, control, data signals and safety protection wires is proposed for the first time, which solves the problem of the original single wire core and draws utility model. B. New technology. The shielding structure solves the electromagnetic interference in the process. By braiding the copper wire shielding layer, the weaving copper wire shielding technology for power, control, data signal and safety protection wires was proposed for the first time, which solved the signal interference problem of power, control, data signal and safety protection wires, and obtained a practical new type. C. Application of new materials By studying the insulation performance, environmental protection performance and temperature and oil resistance of locomotive cables, composite polymer materials were used for the first time to solve the problems of poor volume resistivity, low dielectric strength, poor environmental performance, temperature and oil resistance of cables, etc. Problem, make its volume resistivity reach 1016ω/cm, dielectric strength reach 28mv/m. Through the research on the release of toxic hydrogen chloride gas by chloroprene rubber, the environmental protection technology (low smoke, halogen-free, low toxicity) is proposed for the first time, which meets the Rohs standard. Rubber releases the toxicity of hydrogen chloride poisonous gas. Temperature resistance -45℃~100℃, oil resistance 40%, obtained a utility model patent. Conclusion: This product synthesizes the new achievements of domestic scientific research. New energy cables for new energy vehicle charging devices are mainly used for single-phase AC, power frequency, rated voltage 1kv environmental protection locomotives; this product has good flame retardancy, high and low temperature resistance, acid and alkali resistance, softness, and environmental protection. It has powerful comprehensive environmental protection functions, compact product structure, convenient laying and strong practicability. At the domestic living level, fill the vacancy of domestic projects. .
