The invention discloses an anti-electrostatic screening data cable. Eight copper conductor units are twisted in a two-to-two manner, forming a first, a second, a third and a fourth symmetrical insulated wire pair, the external surfaces of which are respectively winded by a first polytetrafluoroethylene band. The first, the second, the third and the fourth symmetrical insulated wire pair are twisted to the outer surface of an aramid fiber reinforcing piece, forming a cable core. A second polytetrafluoroethylene layer winds around the external surface of the cable core longitudinally. The gap between the second polytetrafluoroethylene layer and the first, the second, the third and the fourth symmetrical insulated wire pair is filled with a plurality of cotton yarns. The external surfaces ofthe metal wires in the metal shielding layer are winded with a third polytetrafluoroethylene band, and the winding direction of the third polytetrafluoroethylene band is opposite to that of the cottonfiber wires. A fourth polytetrafluoroethylene band winds around the external surface of a metal shielding layer longitudinally. The third polytetrafluoroethylene band winds at the superposing position of the connecting place of the metal wire. The invention is advantageous in that during the bending process, sliding can easily occur among the cable core, the metal shielding layer and the outer protecting layer; the stretching of the cable by outer force can be reduced; service lifetime can be prolonged.
