How to choose a very fine coaxial line?

Ultra thin coaxial cable is a special type of coaxial cable with a very small outer diameter and small internal wires, suitable for high space and weight requirements. When customizing ultra-fine coaxial lines, the following are some common requirements and choices:
1. Specifications and dimensions: Determine the required outer diameter, inner diameter, length, and other dimensional specifications. Ultra thin coaxial lines typically have a small outer diameter, typically below a few millimeters, providing a compact installation space. The diameter of internal wires is small, often in the range of tens of micrometers or smaller.
2. Wire material: The internal wires of extremely fine coaxial lines are usually made of high-purity conductor materials such as copper, silver, or gold. The choice of wire material will affect the quality of signal transmission.
3. Shielding and Insulation: Ultra fine coaxial line shielding and insulation performance to reduce signal interference and prevent electrical short circuits. The shielding layer adopts metal braided shielding, aluminum foil shielding or metal foil braided shielding. Common insulation materials include polyethylene (PE) and polytetrafluoroethylene (PTFE).
4. Frequency characteristics: The frequency characteristics of extremely fine coaxial lines are crucial for signal transmission in specific applications. Different ultra-fine coaxial lines have different frequency response ranges and losses. Need to choose an extremely fine coaxial line with frequency range and low loss.
5. Environmental adaptability: Suitable for the environment of extremely fine coaxial lines. Based on the characteristics of the application environment, choose an extremely fine coaxial line with features such as moisture resistance, high temperature resistance, and corrosion resistance.
6. Installation and connection method: Installation and connection method of extremely fine coaxial line. Used for extremely thin wire diameter connectors or joints, Connection and transmission
