In recent years, the development of national rail transit has been rapid, and the control of EMUs and high-speed generators has become more and more complicated. As more and more electrical control devices have been installed, the demand for cables has also increased. However, the space inside the locomotive is limited, so it is required to reduce the insulation thickness of the cable as much as possible to reduce the outer diameter of the cable. This requires increasing the insulation temperature rating to increase the cable's current carrying capacity, improving the mechanical and physical properties of the insulation, and oil resistance to improve the safety performance of the cable.
The thin-walled insulated rail vehicle cable is particularly suitable for high-speed and ultra-high-speed locomotives and other relatively closed, centralized personnel and other environment-demanding internal distribution of rolling stock and power supply systems. The cable is made of tin-plated soft copper conductor and halogen-free low-smoke flame-retardant insulation material. It is produced by thin-wall manufacturing technology. The product is small in size, light in weight, and has heat resistance, oil resistance, acid and alkali resistance, cold resistance, abrasion resistance and ozone resistance. Features, excellent physical and mechanical properties, easy installation, safe use, reliable operation. In the event of a fire, it can effectively limit the spread of fire and the release of smoke and avoid danger to personnel.
The technical key and main technical and economic indicators of this cable are: 1. The mechanical performance and electrical performance meet the requirements of GB/T12528-2008. The insulation of the cable is very thin, only 0.3mm thick. It is a difficult problem to ensure electrical properties and mechanical properties for such a thin insulation thickness. The cables for thin-walled insulated rail transportation vehicles must have excellent mechanical properties. This is also a difficult technology in the production process. 2. The flame retardant performance meets the requirements of GB/T18380-2001. Cables for locomotives are generally required to be flame-retardant and must be halogen-free and low-smoke. 3. Oil resistance. Some parts of the locomotive have lubricating oil or fuel oil, so the cable must have good oil resistance. 4. Temperature rating, 125°C-150°C. The temperature inside the locomotive is high, but it is also running in the south of the country. The working environment is in the wilderness and the area is vast. The environmental conditions vary widely. The temperature fluctuates from -60°C to 125°C. Therefore, the cable should have good cold resistance and good quality. The heat resistance. 5. Excellent ozone resistance.
In April 2012, the Far East Cable R&D Department completed trial production of cables for thin-walled insulated rail transit vehicles. According to the company's 2012 new product research and development plan, this product can obtain the qualified inspection report of the National Wire and Cable Quality Supervision and Inspection Center (Shanghai) in June. In the next few years, there will be steady growth in China's rail transport, and the development of high-speed railways will be extraordinary, so the demand for such cables will increase rapidly. Similarly, its export situation is also very good. It is a product with very good development prospects. The successful development of this product will become the new economic growth point of Far East Cable Co., Ltd.
