摘要： A power cable includes a conductor; an insulator; an inner shield layer; an inner corrosion-proof layer; an outer shield layer; and an outer corrosion-proof layer, provided from center toward outside, wherein only the inner shield layer among the inner shield layer and the outer shield layer is directly grounded at one end of the power cable in an axial direction, and wherein only the outer shield layer among the inner shield layer and the outer shield layer is directly grounded at the other end of the power cable in the axial direction.

摘要： A method is provided for reducing the stray noise associated with the transmission of the electrical power between a power source and a target. The method includes the step of interconnecting the power source and the target with a conductor. A shield is positioned about the conductor to prevent electromagnetic and radio frequency interference from passing therethrough. A low impedance path is provided for the stray noise to travel between a neutral point of the power source and the isolated target.

摘要： A power cable includes a steel pipe coupled to a reference potential node, three transmission cables within the steel pipe and respectively including a conductor to transmit three-phase alternating current power, and a return cable within the steel pipe and coupled to the reference potential node. Each of the three transmission cables includes a first insulating layer covering the conductor, a metal layer covering the first insulating layer, and a second insulating layer covering the metal layer. The three transmission cables are twisted around a periphery of the return cable along a longitudinal direction of the return cable, and the metal layer is coupled to the reference potential node.

摘要： A coaxial three-phase servo motor power cable is comprised of a shielded twisted triple cable which transmits three phase electrical power from a servo amplifier to a servo motor, with the shield being electrically insulated and mechanically floating within an air void that exists inside a conduit having a diameter much greater than the shielded twisted triple cable. The conduit is covered by a braid shield, which is covered by shrink tubing which may be overlaid by one or more additional signal wires, with this entire assembly being further covered by an over braid shield, which is covered by an outer insulating sheath. Both the conduit braid shield and over braid shield are electrically terminated to back shells at each end of a cable assembly.

摘要： A cable arrangement where three cables have at least two cross-bonding locations when transmitting power between a first location and a second location. At the cross-bonding location not only the screens but also the water sensing wires are cross-bonded in cross-bonding devices. Thus, voltage differences between the water sensing wires and the screens of the respective cables in the three-phase system can be avoided. A particular application is found in high power transmission systems using high voltage cables.

摘要： A wire harness includes first, second and third power cables, first, second and third conductive electromagnetic shielding members, and an intermediate short-circuit member. The power cables are arranged to conduct symmetrical three-phase AC electricity. The conductive electromagnetic shielding members are arranged in parallel to each other and spaced apart from each other, each of the conductive electromagnetic shielding members disposed surrounding respective ones of the power cables. The intermediate short-circuit member is arranged to electrically connect the electromagnetic shielding members to one another in at least one intermediate region between first and second longitudinal ends of each of the electromagnetic shielding members. The intermediate short-circuit member has a conductive member arranged to electrically connect the electromagnetic shielding members to one another, and a nonconductive armoring section arranged to cover an outer surface of the conductive member.
