Technical requirements for super-six category 4 pairs of unshielded twisted pair low-smoke halogen-free type

　　Super 6 Category 4 Pair Unshielded Twisted Pair Low SMoke Halogen Free Type (hereinafter referred to as "Super 6 Category Low Smoke Halogen Free Twisted Pair") is a high-performance network transmission cable. Its technical requirements cover multiple aspects to ensure transmission efficiency, safety and durability. The following is a detailed analysis of its technical requirements:

　　First, conductors and insulation layers

　　Conductor material: Super six low-smoke halogen-free twisted pair usually uses high-purity copper as the conductor material to ensure good electrical conductivity and signal transmission quality.

　　Conductor size: The diameter of the conductor usually meets the 23AWG (American wire gauge) standard, which is a measure of the thickness of the conductor, which directly affects the current transmission capacity and the degree of signal attenuation.

　　Insulating layer material: The insulating layer is made of high-density polyethylene (HDPE) or other high-performance insulating materials to provide excellent electrical insulation properties and physical and mechanical strength.

　　Second, the cable structure

　　Cable core count: Super six low-smoke halogen-free twisted pair consists of four pairs of twisted pairs, each pair of twisted pairs is twisted together by two different-colored wires to reduce electromagnetic interference and signal attenuation.

　　Cross skeleton structure: The cable is equipped with a cross skeleton structure, and four pairs of twisted pairs are respectively fixed in the grooves of the skeleton to maintain the balance characteristics and crosstalk attenuation performance of the cable.

　　Low-smoke halogen-free material: The outer sheath is made of low-smoke halogen-free flame retardant material to meet the requirements of safety and environmental protection. When burned, this material does not produce toxic smoke and halogenated hydrogen gas, and is less harmful to the environment and human health.

　　III. Electrical performance

　　Transmission bandwidth: The transmission bandwidth of Super Category 6 low-smoke halogen-free twisted pair typically reaches or exceeds 500MHz, supporting high-speed data transmission and multimedia applications.

　　Impedance matching: The characteristic impedance of the cable is usually around 100 ohms to ensure the stability and integrity of the signal during transmission.

　　Attenuation and crosstalk: The attenuation and crosstalk performance of the cable must meet the requirements of relevant international standards to ensure the quality and reliability of the signal over long distances.

　　IV. Mechanical properties and environmental adaptability

　　Tensile strength: The cable needs to have a certain tensile strength to withstand the tension during installation and use.

　　Bending radius: Cables need to follow certain bending radius requirements when laying to avoid excessive bending causing cable damage or performance degradation.

　　Temperature range: The cable needs to be able to work properly within a certain temperature range, including installation temperature and operating temperature. Usually, the installation temperature range is 0 ° C to + 50 ° C, and the operating temperature range is -20 ° C to + 60 ° C (or higher).

　　Flame retardancy: The cable needs to have excellent flame retardancy to meet fire safety requirements.

　　V. Certification and Standards

　　Certification: Super six low-smoke halogen-free twisted pair must pass the certification of relevant international or domestic certification bodies, such as UL, CE, RoHS, etc.

　　Standard: The cable must meet the requirements of relevant international standards or domestic standards, such as ANSI/TIA-568-C.2, YD/T 1019, etc.

　　To sum up, the technical requirements of the super six low-smoke halogen-free twisted pair cover conductors and insulation layers, cable structure, electrical properties, mechanical properties and environmental adaptability, as well as certification and standards. These requirements ensure the excellent performance of the cable in terms of transmission efficiency, safety and durability.
