技术领域 technical field
本实用新型涉及一种电缆，特别涉及一种轨道交通用耐高温耐辐照超轻型信号电缆。 The utility model relates to a cable, in particular to a high-temperature-resistant and radiation-resistant ultra-light signal cable for rail transit.
背景技术 Background technique
随着新型轨道交通和电子工业及国防工程的飞速发展，对信号传输用的电缆提出更高的要求，电缆向小型化、重量轻、耐高温等方向发展。一般的耐高温信号电缆采用聚全氟乙丙稀、聚四氟乙烯等氟材料作为绝缘材料，绝缘为挤出包覆结构，此类产品外径相对较大，重量比较重，屏蔽效果差，不能满足新型轨道交通的要求。 With the rapid development of new rail transit, electronic industry and national defense projects, higher requirements are placed on cables for signal transmission, and cables are developing in the direction of miniaturization, light weight, and high temperature resistance. General high-temperature-resistant signal cables use fluorine materials such as polyfluoroethylene propylene and polytetrafluoroethylene as insulating materials, and the insulation is an extrusion-coated structure. The outer diameter of such products is relatively large, the weight is relatively heavy, and the shielding effect is poor. Can not meet the requirements of new rail transit.
发明内容 Contents of the invention
鉴于现有技术存在的不足，本实用新型提供了一种轨道交通用耐高温耐辐照超轻型信号电缆。 In view of the deficiencies in the prior art, the utility model provides a high-temperature-resistant and radiation-resistant ultra-light signal cable for rail transit.
本实用新型为实现上述目的，所采取的技术方案是：一种轨道交通用耐高温耐辐照超轻型信号电缆，包括内导体、绝缘层、屏蔽层、护套层，在所述内导体外依次设有一层辐照交联乙烯-四氟乙烯绝缘层、铜带屏蔽层、辐照交联乙烯-四氟乙烯护套层。 In order to achieve the above purpose, the utility model adopts the following technical solution: a high temperature and radiation resistant ultra-light signal cable for rail transit, including an inner conductor, an insulating layer, a shielding layer, and a sheath layer, and A radiation cross-linked ethylene-tetrafluoroethylene insulating layer, a copper tape shielding layer, and a radiation cross-linked ethylene-tetrafluoroethylene sheath layer are provided in sequence.
本实用新型的有益效果是：1、耐高温：由于内导体采用了镀银铜导体，常时耐温可达200℃，绝缘层和护套层均采用了辐照交联乙烯-四氟乙烯，经辐照交联后的乙烯-四氟乙烯耐温均可达到200℃，能够经受300℃×7H的老化试验。耐低温：辐照交联乙烯-四氟乙烯绝缘材料的长时间工作温度可达-100℃，可以用于极限低温的场所。 The beneficial effects of the utility model are: 1. High temperature resistance: Since the inner conductor adopts a silver-plated copper conductor, the temperature resistance can reach 200°C at ordinary times, and both the insulating layer and the sheath layer adopt irradiation cross-linked ethylene-tetrafluoroethylene. The temperature resistance of ethylene-tetrafluoroethylene after irradiation crosslinking can reach 200°C, and it can withstand the aging test of 300°C×7H. Low temperature resistance: The long-term working temperature of radiation cross-linked ethylene-tetrafluoroethylene insulation material can reach -100 ℃, which can be used in places with extreme low temperature.
2、外径小、重量轻：内绝缘层厚度仅有0.10mm、护套层厚度也仅有0.10mm，乙烯-四氟乙烯绝缘材料的密度为1.7g/cm3 ,而其他氟材料的密度一般为2.1 g/cm3，比普通氟塑料安装线的重量要减小40%左右。 2. Small outer diameter and light weight: the thickness of the inner insulating layer is only 0.10mm, and the thickness of the sheath layer is only 0.10mm. The density of ethylene-tetrafluoroethylene insulating material is 1.7g/cm 3 , while the density of other fluorine materials is Generally 2.1 g/cm 3 , which is about 40% lighter than ordinary fluoroplastic installation wires.
3、机械性能好：辐照交联乙烯-四氟乙烯此种材料的强度很高，具有很高的耐割能力，大大提高了绝缘的机械性能，此种材料辐照后的强度平均可达40Mpa。 3. Good mechanical properties: irradiation cross-linked ethylene-tetrafluoroethylene material has high strength and high cutting resistance, which greatly improves the mechanical properties of insulation. The average strength of this material after irradiation can reach 40Mpa.
4、阻燃性好：采用辐照交联乙烯-四氟乙烯此种材料的氧指数可达40，具有很高的阻燃性能，可以应用于复杂高温环境。 4. Good flame retardancy: The oxygen index of this material can reach 40 by using irradiation cross-linked ethylene-tetrafluoroethylene, which has high flame retardancy and can be applied in complex high-temperature environments.
5、柔软：由于导体采用了0.08mm极细的镀银铜丝绞合构成，所以大大提高了电缆的柔软性，电缆很容易敷设安装。 5. Softness: Since the conductor is made of 0.08mm ultra-fine silver-plated copper wire twisted, the flexibility of the cable is greatly improved, and the cable is easy to lay and install.
6、屏蔽效果好，使用铜带作为屏蔽层，绕包搭盖率15%以上，屏蔽效果可以达到95%以上。 6. The shielding effect is good. Copper tape is used as the shielding layer. The covering rate of the wrapping is over 15%, and the shielding effect can reach more than 95%.
