Computer cables are a type of electrical equipment cable, suitable for electronic computers and automatic instruments with high requirements for interference resistance at rated voltages of 500V or less. Depending on different environmental and equipment usage requirements, the cable insulation can be made of materials such as polyethylene, polyvinyl chloride, cross-linked polyethylene, fluoroplastic, and silicone rubber.
The individual pairs of shielded twisted pairs should not be disconnected from each other, nor should they be disconnected from the overall shield.
The cores of the cables and between the cores and the shielding or other metal layers should withstand 50Hz, alternating voltage of 2000V for 1 minute or 1500V for 5 minutes without breakdown.
High insulation resistance, good voltage resistance, small dielectric constant, and minimal temperature and frequency dependence of dielectric loss in polyethylene not only meet the transmission performance requirements but also ensure the cable's service life.
To minimize mutual interference between circuits and external disturbances, the cable must be constructed with a shielding structure. Shielding materials include tin-plated or untinned copper wire, copper strip, copper-plastic composite tape, and aluminum-plastic composite tape, among others. The metallic strips are produced by wrapping, with an overlap rate typically not less than 15%, but specific standards may have special provisions; for instance, TICW/06 specifies that the overlap rate of the shielding metallic strip should not be less than 25%. The metallic wire is produced by weaving, with a weaving coverage rate not less than 80%, and may not be less than 90% if higher anti-interference requirements are needed.
The shielding requirements for cables are adopted separately for different scenarios: segmented shielding (only for twisted pairs, with each twisted pair having its own shielding), overall shielding (the cable has only one overall shielding layer after the core is stranded), and segmented + overall shielding (combining both of the above structures). To meet higher requirements from users and usage scenarios, the overall shielding structure can be implemented using a composite shielding method, which includes two layers of shielding, consisting of metal tape wrapping and metal wire braiding.
Note: If the cable has a segmented shielding structure, the shielding layers should have good insulation properties, and polyester tape or other non-absorbent wrapping tape should be applied on the outer side of the segmented shielding.
