RF coaxial cable structure and main technical performance

RF coaxial cable is a type of cable widely used in communication, television, radar and other fields. Its structure and main technical performance include the following aspects:

1. Core wire

The core wire is the core part of an RF coaxial cable, which is composed of one or more copper wires. These copper wires are usually twisted together to improve the transmission performance of the cable. The diameter and material of the core wire can affect the electrical performance of the cable, such as impedance, attenuation, etc. According to different frequencies and transmission requirements, the structure of the core wire can be divided into solid copper wire, copper clad steel wire, copper clad aluminum wire, etc.

2. Insulation layer

The insulation layer is an important part of RF coaxial cables, located between the core wire and the shielding layer. The main function of the insulation layer is to isolate the core wire and the shielding layer, preventing current from flowing from the core wire to the shielding layer. In addition, the insulation layer also needs to withstand high voltage to ensure the safety of the cable. There are many types of insulation materials, such as polyethylene, polyvinyl chloride, fluoroplastics, etc. The thickness and material of the insulation layer can affect the electrical performance and mechanical strength of the cable.

3. Shielding layer

The shielding layer is an important component of RF coaxial cables, located on the outer side of the insulation layer. The material of the shielding layer is usually a metal material with good conductivity, such as copper, aluminum, etc. The function of the shielding layer is to prevent external electromagnetic interference from entering the cable and to prevent internal signal leakage. The structure and thickness of the shielding layer will affect the electrical performance and mechanical strength of the cable.

4. Coat

The jacket is the outermost layer of RF coaxial cables, usually made of high-temperature and corrosion-resistant plastic or rubber. The function of the jacket is to protect the cable from the influence of the external environment, while improving the mechanical strength of the cable. The thickness and material of the jacket can affect the mechanical and protective properties of the cable.

 

In summary, the structure and main technical performance of RF coaxial cables are key factors to ensure their electrical and mechanical performance. Understanding these structures and performance can help to better use and maintain these types of cables.
