24 Pairs 1.5mm2 Double Shielded Twisted Pair Instrument Cable Computer Cable

Product DescriptionComputer cables belong to electrical equipment cables. This cable is suitable for electronic computers and automation instruments with a rated voltage of 500V or less that have high requirements for anti-interference. According to different environments and equipment usage requirements, cable insulation can be made of polyethylene, polyvinyl chloride, cross-linked polyethylene, fluoroplastics, silicone rubber, and other materials.Minimum bending radius: For unarmored structures, it should not be less than 6 times the outer diameter of the cable, and for armored or copper tape shielded structures, it should not be less than 12 times the outer diameter of the cable. The insulation resistance shall comply with the following requirements after stable charging with a DC 500V voltage test at 20 ºC for 1 min: there shall be no open circuit between each pair of shields and between the pair shield and the total shield. The cable core and core, as well as between the core and the shield or other metal layers, shall withstand 50 Hz, and the AC voltage shall be 2000 V/1 min or 1500 V/5 min without breakdown. Polyethylene has high insulation resistance, good voltage resistance, low dielectric coefficient, and low impact of dielectric loss temperature and frequency variation. It not only meets the requirements of transmission performance, but also ensures the service life of the cable. In order to reduce mutual crosstalk and external interference between loops, cables need to be shielded. Shielding materials include tinned or non tinned copper wire, copper tape, copper plastic composite tape, aluminum plastic composite tape, etc. The metal tape is produced by wrapping, and the coverage rate should generally not be less than 15%. However, specific standards have special provisions, such as the provisions of TICW/06 that the coverage rate of shielding metal tape should not be less than 25%; The metal wire shall be produced by weaving, and the weaving coverage rate shall not be less than 80%. If there are high requirements for anti-interference, the coverage rate may not be less than 90%. The shielding requirements for cables are based on different occasions: sub shielding (only for twisted pairs, and each twisted pair has a shielding), total shielding (only for cables with a layer of total shielding after the cable core is assembled), and sub shielding+total shielding (both structures are included). According to the higher requirements of users and applications, the overall shielding structure can adopt a composite shielding method, which includes two layers of shielding, consisting of metal tape wrapped and wire woven.
