Application Scenarios of Fluoroplastics in The Cable Industry

PublishTime： 2023-10-28 Article Source：Futureway News

High-frequency data transmission wire and cable

Fluoroplastics not only have outstanding electrical insulation, but also have a low dielectric constant and a particularly low loss factor, dielectric strength, dielectric constant (2.3~2.1), and volume resistivity in a wide temperature range and frequency range. The surface resistivity and surface resistivity are maintained well, and their glass transition temperature is not affected by temperature; they have low hygroscopicity so that the dielectric properties are rarely affected by humidity; the electrical properties of fluoroplastics (F4) do not change with time; It is inert to almost all chemicals and solvents, and can maintain their excellent performance even under high temperature and pressure. It is especially suitable for data transmission cables that require low attenuation. Therefore, they are used in some occasions that require high-temperature resistance and fire resistance. As the insulating medium of the radio frequency cable, it is helpful to improve the quality of the transmission signal. The fluorine plastic is used as the insulating layer and the outer sheath.

Connecting lines for key parts of the automotive industry

Another important use of fluoroplastics is: used as connecting wires in harsh environments. The maximum operating temperature is 250°C. Fluoroplastic insulated cables can pass the UL standard 80°C oil resistance test. There are also many places where fluoroplastics insulated wires are used in cars, such as Cables of an automatic transmission for corrosive oil; gasoline oil level sensors; brake friction sensors, etc.

Network cabling in the construction industry

As the world’s urbanization accelerates, high-rise buildings increase, people’s awareness of wire and cable fires has increased, and the requirements for cable fire prevention in various fields have become higher and higher. Coupled with the limitation of the installation space, the wire and cable diameters are required. Small, large current-carrying capacity, high thermal stability, high flame retardancy, and low loss of fluoroplastics have become hotspots of concern. The use of fluoroolefin plastics to insulate connecting wires for special occasions can meet the above requirements. The country mandates that the wiring must use fluorine plastic network cables.

Drilling cables in the petroleum industry

Since the temperature of the steam to be injected is as high as 300℃ and the pressure can reach 20MPa, the inside of the oil well is in a high-temperature and high-pressure environment all year round. Therefore, for cables working in this high-temperature and high-pressure environment, how to overcome the severe transmission of logging data to the well has become an important issue. Fluoroplastic cables have the characteristics of high-temperature resistance, can keep working at a high temperature of 300 ℃, and have excellent pressure resistance. Therefore, they are also more and more widely used in the petroleum industry. Fluoroplastics and BASF's TPU sheath are currently the standard for this type of cable.

Special cables for the power industry

The application environment of wires and cables in the power industry is very complex, high temperature (stator, rotor, air cooler inlet), soaking liquid (oil tank, oil pipeline, water pipeline, and transformer), easy to be mechanically damaged (machine pit, wind tunnel), The requirements are very demanding. Fluoroplastic cables can effectively overcome these harsh environments and are suitable for the use of cables, high-temperature resistant cables in the power industry.

Aerospace cable

Wires and cables are materials that connect power sources and electrical equipment and electrical equipment to form an aircraft electrical network. With the increasing development of the aviation industry the improvement of aircraft performance and the update of airborne equipment, the amount of information transmitted by the aircraft Increasing, the transmission line that plays the role of "nerve" and "blood vessel" in the entire aircraft system has higher and higher performance requirements, especially the complicated internal environment of the aircraft. The application of wire and cable should consider its electrical performance and mechanical properties. In addition to performance and chemical properties, the electrical network matching relationship, anti-interference ability, current carrying capacity, use environment, mechanical strength, cable protection, and other factors should also be considered comprehensively. Fluoroplastic cables have lightweight, anti-interference, and excellent physical and chemical properties. , Is playing an increasingly important role in aerospace.
