Insulation materials for computer cables include polyethylene (PE), polyvinyl chloride (PVC), cross-linked polyethylene (XLPE), fluoroplastics, and silicone rubber. The choice of material depends on factors such as the cable's operating temperature, environmental requirements, and cost. For instance, polyethylene and cross-linked polyethylene offer high insulation resistance and voltage withstand capabilities, making them suitable for high-temperature environments.
Shielding materials include tinned or untinned copper wire, copper tape, copper-plastic composite tape, and aluminum-plastic composite tape. The shielding structure is designed to minimize crosstalk between circuits and external interference, thereby ensuring stable signal transmission.
