What is the process flow of very fine coaxial cable processing? What is a very fine coaxial line?

Extremely fine coaxial cable is a kind of cable used for transmitting high-frequency signals, which is widely used in the fields of communication, radio spectrum analysis, and medical equipment. It consists of a center conductor, an insulating layer, an outer conductor and an outer jacket, and has low transmission loss and high signal transmission quality. The manufacture of very fine coaxial cable requires multiple processes, and the following is a typical process flow for processing very fine coaxial cable: 1. Material Preparation: Select suitable center conductor, insulation, outer conductor and outer sheath materials, and ensure that they comply with the relevant standards and requirements. 2. Center Conductor Preparation: Use suitable materials (e.g., copper, silver, etc.) to make the center conductor. First of all, select the appropriate conductor wire, and make it reach the required diameter and roundness through the process of drawing or extruding, etc. 3. Insulation application: Coat the insulating material on the center conductor. This can be accomplished by dip-coating, extruding or spraying. Ensure the thickness and uniformity of the insulation layer to provide good insulation. 4. Outer conductor application: An outer conductor is applied on top of the insulation layer. The outer conductor is usually made of a fine wire braid or thin metal foil, and is used to provide electromagnetic shielding protection and grounding. 5. Outer Sheath Preparation: The outer sheath material is placed over the outer conductor to form the outermost layer of protection for the cable. The outer jacket is usually made of materials such as polyvinyl chloride (PVC) or polyethylene (PE), which are resistant to abrasion, chemicals, etc. 6. Wire Forming: The cable is formed by wire forming equipment to give it the desired outside diameter and roundness. This step usually involves processes such as drawing, extruding or winding.7. Inspection and testing: Finished cables are inspected and tested to ensure that their performance meets the specified standards and requirements. Common tests include resistance testing, insulation testing, shielding effectiveness testing, etc. 8. Packaging and Delivery: The inspected and tested cables are packaged and ready for delivery to the customer or the next step in the supply chain. The manufacturing process for very fine coaxial cables requires a high degree of sex and process control to ensure that the cables have good signal transmission performance and reliability. Each process step requires strict adherence to defined standards and requirements to ensure the quality and performance of the final product. In addition, as technology continues to evolve, the process of manufacturing very fine coaxial cables is constantly being innovated and improved to meet the growing demand for high frequency transmission.
