Structure of Coaxial Cable RG9:
Inner conductor: Bare copper/Copper Clad Aluminum /Copper Clad Steel
Dielectric: Foam PE
Shield: Al Foil+ Al Braiding+ Al Foil
Jacket: PE/PVC
Application of Coaxial Cable RG9:
Coaxial cables are widely used in the transmission of radio frequency or audio and video, and are suitable for a variety of applications, such as cable television, long-distance calls, etc.
Feature:
1. The foaming degree is as high as 80%, no polar molecule residues are contained, and the transmission characteristics are excellent.
2. The micropores in the medium layer are evenly sealed, impervious to water and air, stable performance and long service life.
3. High-quality aluminum foil ensures the shielding performance and service life of the cable. Whether the braided layer is aluminum-magnesium-gold wire or tinned copper wire, it is close to the aluminum foil and will not be embedded in the sheath.
4. The outer conductor adopts argon arc welding technology, and the reliable high-speed welding technology ensures the performance of the product, especially the electrical characteristics and mechanical strength.
5. The anti-corrosion layer adopts a special modified asphalt as the material of the main formula, and it is evenly coated between the outer conductor of the cable and the sheath, which has the functions of anti-corrosion, moisture-proof and self-healing of the cable protective layer.
