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.
