What is the international standard for wire diameter of network cable engineering?

　　The international standards for cable diameter are mainly marked according to the American wire specification (AWG). The following is a detailed explanation of the international standards for cable diameter:

　　AWG standard

　　Definition: AWG is a standard for distinguishing the diameter of round copper conductors established by the United States in 1887, and is only applicable to copper conductors.

　　Calculation formula: Dn = 0.005 × 25.4 × 92 ^ (36-n/39) (mm), where Dn represents the diameter of the conductor and n represents the wire gauge number (e.g. 23AWG, 24AWG, etc.).

　　Second, various network cable diameter standards

　　Category 5 and Super Category 5 lines:

　　AWG standard: 24AWG

　　Diameter conversion: Converted to the national standard diameter of about 0.511mm, converted to square numbers of about 0.2mm ².

　　Actual production: Most manufacturers on the market produce super-Category 5 network cables with a wire diameter between 0.50mm and 0.52mm, which is the minimum requirement.

　　Category 6 and Super Category 6 Lines:

　　AWG Standard: 23AWG

　　Diameter conversion: Converted to the national standard diameter of about 0.574mm, converted to square numbers of about 0.26mm ².

　　III. Precautions

　　The diameter of the network cable must be produced in strict accordance with the requirements of US wire regulations. If it is too SMall, the cable performance will be reduced, and if it is too large, it will cause material waste.

　　When selecting a network cable, in addition to paying attention to the wire diameter, it is also necessary to pay attention to the material, shielding method, transmission rate and other parameters of the network cable to ensure the stability and speed of network transmission.

　　To sum up, the international standards for wire diameter of network cable engineering are mainly marked according to AWG, and the wire diameter standards of various network cables are different. When selecting network cables, they should be purchased in strict accordance with relevant standards to ensure the quality and stability of network transmission.
