What is the material of the shielded network cable?

　　The materials for shielding network cables mainly include the following:

　　Conductor material: The inner conductor of the shielded wire is usually made of oxygen-free copper (OFC) or tinned copper. Oxygen-free copper has high electrical conductivity and ensures stable signal tranSMission. Tinned copper has good oxidation and corrosion resistance and is suitable for some special environments.

　　Insulation material: The insulation layer in the network cable is usually made of plastic materials such as high-density polyethylene (HDPE) or polyvinyl chloride (PVC). These materials have good electrical insulation properties and mechanical strength, which can protect the conductor from external damage.

　　Shielding layer material: The shielding mesh wire is wrapped with one or more shielding layers outside the conductor to resist electromagnetic interference. Common shielding layer materials include aluminum foil, braided mesh (such as copper mesh or aluminum-magnesium alloy mesh), and a combination of metal foil and braided mesh. The aluminum foil shielding layer has good conductivity and flexibility, and is easy to process and install; the braided mesh shielding layer provides higher shielding efficiency and mechanical strength.

　　Skin material: The outermost layer of the shielded cable is usually made of materials such as flame retardant PVC or Low Smoke Zero Halogen (LSZH). These materials not only have excellent electrical properties and mechanical strength, but also provide additional safety in the event of an emergency such as a fire.

　　In summary, the material selection of the shielded network cable has a significant impact on its performance and service life. When selecting a shielded network cable, the advantages and disadvantages of various materials should be weighed according to actual needs and budget to ensure that the most suitable network cable product for your application is selected.
