Non-shielding type anti-interference data cable having cable core coated with non-metal material and fabrication method of data cable

The invention relates to a non-shielding type anti-interference data cable having a cable core coated with a non-metal material and a fabrication method of the data cable. The cable comprises four pairs of twisted lines and is characterized in that the four pairs of twisted lines are separated by a conventional cross framework, a conductor of each pair of twisted lines is a single-copper wire conductor 30-22AWG and a multi-strand twisted conductor 30-22AWG, the external diameter of the single-copper wire twisted lines is 0.90-1.26 millimeters, the external diameter of multi-stand copper wire twisted lines is 0.70-1.35 millimeters, the non-metal material wraps an outer layer of the cable core, and a PVC or low smoke zero halogen sheath material wraps the outermost layer to form a cable product. The cable has the characteristics that a crosstalk interference index among cables can be reached, the external sizes of the cross framework and the cable are reduced, the application of the cable under a convention occasion is satisfied, and the cable cost is effectively reduced.
