The times are developing, people's living standards are improving, and people have more and more means of transportation. At present, automobiles are the most commonly used means of transportation in people's travels. With the widespread use of automobiles, the harm to the environment is becoming more and more serious, and the requirements for tools are also getting higher and higher. The use of traditional fuel vehicles will emit a large amount of exhaust gas, causing environmental pollution and exacerbating the lack of resources and oil. Therefore, the application of new energy vehicles is a product that takes advantage of the development of the times and market demand, and the corresponding level of components required for vehicles should also be improved. In the development of new energy vehicles, China's R&D level and independent innovation capabilities are quite different from those in the world, which has affected the development of China's new energy vehicle industry. Therefore, as an important part of new energy vehicle cables and vehicle systems, its research and development work is very important. In order to meet the needs of social development and provide special supporting wire and cable products for new energy vehicles, our company has increased investment in research and development and prepared professional and technical personnel to actively develop special wire and cable products for new energy vehicles. New energy automotive cables are special cables with high technical requirements, which raises the market entry threshold of the industry. If the technical level of the enterprise is relatively backward, it will be difficult to enter. Therefore, enterprises must carry out research and development of new energy automotive cable products, and be at the forefront of industry technology. 1. Main technical performance. The new energy vehicle charging device cable has the following technical properties through market research and analysis, and according to the relevant technical requirements put forward by customers: (1) Insulation and outer sheath of flame-retardant, high-efficiency and environmentally friendly materials. (2) Excellent waterproof, acid and alkali resistance, and oil resistance: the insulation and sheath of the cable are made of tpv and tpu, and its material has good acid and alkali resistance, good corrosion resistance to polar oil, and clean to acid and alkali The anti-corrosion agent has strong resistance, so that the cable can still maintain its original characteristics after long-term use in an acid-base environment. (3) Environmentally friendly and harmless low-smoke and halogen-free performance. 2. Select the structure and material of the cable. 2.1 Product structure. Select 2.2 cable material. (1) The copper core soft conductor is used for the conductor cable, and the conductor should meet the requirements of the sixth conductor of the GB/T3956-2008 standard. (2) The insulation is made of high-quality thermoplastic vulcanized rubber tpv material. The material has excellent electrical properties, elasticity and pressure deformation resistance, which can make the cable soft, oil resistant, high and low temperature resistant, and environmentally friendly. (3) The shielding of the insulated core of the shielded cable shall consist of a separate shield, a total shield and an aluminum-plastic composite tape. (4) Cable twisted power supply, control, data signal and safety protection lines. (5) Outer sheath The outer sheath is extruded with environmentally friendly halogen-free low-smoke flame-retardant radiation cross-linked sheath. The extruded sheath should be smooth, round and free of quality defects such as scorch, scratches, and air bubbles. .
