Abstract: A transmission line includes a conductor for signal transmission and an isolating layer covering the conductor. The isolating layer includes a first isolating strand group and a second isolating strand group. The first isolating strand group is wound in a way that forms an S-twist around the conductor along an axis direction the conductor, and the second isolating strand group is wound in a way that forms a Z-twist around the conductor along the axis direction. In an interval from a first position to a second position, including the first position, the first isolating strand group continuously overlaps an outside of the second isolating strand group, and in an interval from the second position to a third position, including the second position, the second isolating strand group continuously overlaps an outside of the first isolating strand group.

Abstract: A cable is provided. The cable comprises a conductor for transmitting electrical signals, an insulating layer covering the conductor along the length direction of the cable, and a shield layer covering the insulating layer along the length direction of the cable. The shield layer comprises multiple conductive flat wires which are spirally wound along the length direction of the cable to cover the insulating layer, and the conductive flat wires are parallel to each other and do not overlap with each other.
