Abstract
The invention discloses a power cable with a high signal to noise ratio. The power cable comprises three main conducting lines and at least one auxiliary conducting line. The axes in the axial direction of the three main conducting lines are arranged in a triangular shape. At least a part of the auxiliary conducting line is located in a gap space among the main conducting lines. The peripheries of the main conducting lines and the auxiliary conducting lines are filled with insulation materials and covered with the insulation materials into a whole. The peripheries of the insulation materials are provided with a corrugated aluminum sheath. The periphery of each corrugated aluminum sheath is provided with an armor layer formed by two layers of armor electric wires in a winding mode and the armor electric wires of the two armor layers are wound in different directions. The periphery of each armor layer is covered with a protective sleeve. Each main conducting line comprises a core line conductor and a shielding layer covering the core line conductor and each auxiliary conducting line comprises a plurality of densely-arranged core line conductors and a shielding layer covering the core line conductors. The diameter of each core line conductor of each auxiliary conducting line is smaller than that of the core line conductor of each main conducting line and the diameter of each auxiliary conducting line is smaller than that of each main conducting line. One main conducting line serves as a signal transmission line. The power cable with the high signal noise ratio is simple in structure and high in anti-jamming capacity.
