In numerous electrical and electronic systems, the performance of cables plays a crucial role. Especially in scenarios where equipment operates in high - temperature environments, high - temperature resistant coaxial cables have become indispensable key components.
I. Structural Analysis
1. Conductor: Tinned copper is used as the conductor material. This type of conductor has excellent electrical conductivity and corrosion resistance. The tin - plating layer can effectively prevent the copper conductor from being oxidized during the usage process, ensuring the stable electrical performance of the cable during long - term use. Good electrical conductivity can reduce energy loss during signal transmission and guarantee efficient signal transfer.
2. Insulation Layer: The insulation material is FEP (fluorinated ethylene propylene). FEP has outstanding insulating properties, which can effectively isolate the conductor from the outside, preventing signal leakage and short - circuit phenomena. At the same time, it also has excellent high - temperature resistance. It can maintain stable physical and chemical properties in high - temperature environments, ensuring the normal operation of the cable.
3. Number of Cores: This coaxial cable has a single - core structure. This relatively simple structural design is suitable for some application scenarios with relatively simple signal transmission requirements, enabling it to focus on providing a stable transmission channel for a single signal.
4. Shielding Layer: The shielding layer is made of tinned copper braid. It can effectively shield external electromagnetic interference, ensuring that the signals transmitted inside the cable are not affected by external electromagnetic fields. The tinned copper shielding layer not only has a good shielding effect but also has a certain degree of flexibility, which is convenient for cable installation and wiring.
5. Jacket: The cable jacket is made of SILICONE (silicone rubber) material. Silicone rubber has good high - temperature and low - temperature resistance. It can maintain good elasticity and mechanical properties within a wide temperature range from - 40°C to + 200°C. At the same time, it also has characteristics such as waterproofness, moisture resistance, and chemical corrosion resistance, which can provide comprehensive protection for the internal structure of the cable.
II. Electrical Performance
1. Rated Voltage: The rated voltage of this coaxial cable is 300/500V, which means it can operate safely and stably in an environment with a phase voltage of 300V and a line voltage of 500V. This rated voltage design makes it suitable for a variety of medium - and low - voltage electrical equipment and electronic systems.
2. Rated Temperature: Its operating temperature range is from - 40°C to + 200°C, demonstrating excellent high - temperature and low - temperature resistance. In high - temperature environments, such as industrial furnaces, high - temperature drying equipment, etc., it can work normally without performance degradation or damage due to excessive temperature. In low - temperature environments, such as outdoor equipment in cold regions, cold storage, etc., it can also maintain good flexibility and electrical performance, ensuring the normal operation of equipment.
III. Application Fields
Due to its excellent properties such as high - temperature resistance and anti - interference, this high - temperature resistant coaxial cable is widely used in multiple fields. In the aerospace field, it is used for signal transmission of sensors, control systems, and other equipment around aircraft engines; in the industrial automation field, it can be used for connecting automated production lines, robots, and other equipment in high - temperature environments; in the petrochemical industry, it is suitable for wiring of instruments, monitoring systems, etc. in high - temperature and corrosive environments such as oil refineries and chemical plants.
In conclusion, this
high - temperature resistant coaxial cable with specific structures and properties, relying on its excellent high - temperature and low - temperature resistance, as well as good electrical performance and shielding effects, plays an important role in many high - temperature application scenarios, providing reliable guarantees for the stable operation of various types of equipment.
