The present invention provides a torsion resistant shielded cable which includes at least one conductor; an insulating layer covering outside the conductor; a first isolating layer surrounding the insulating layer; and a shielded layer including a number of wires, single wires or strand wires, wound around the first isolating layer in a clockwise and counter-clockwise alternative order along an axial direction of the conductor to prevent the strand wires from breaking while the torsion resistant shielded cable is twisted.
