摘要： A water barrier for encapsulating a cable core has an inner layer of lead-free metal foil having an elastic modulus lower than 210 GPa, an intermediate layer of adhesive material, and an outer layer of a polyethylene-based semi-conducting polymer having an elastic modulus higher than 0.5 GPa. A power cable is providing having such a water barrier.

摘要： Disclosed is a circuit breaker monitoring a power line. The circuit breaker is provided with a power line monitoring circuit including a leakage current detecting circuit and a state judging circuit to monitor the on-off state of the shielding wire of the power line. When there is a leakage current between the phase and neutral wire of the power line and the shielding network wire is disconnected, the circuit breaker can automatically cut off the connection between the electrical appliance and the power supply to avoid the electric shock and fire accidents.

摘要： A composite conducting element, a power line and a manufacturing process of the composite conducting element. The composite conducting element includes a non-woven fabric layer, at least one wire body and a conducting layer component. The wire body is arranged on at least one surface of the non-woven fabric layer and the wire body extends along a length direction of the non-woven fabric layer. The conducting layer component covers at least one surface of the non-woven fabric layer and the wire body is located between the conducting layer component and the non-woven fabric layer. The wire body is conductively connected with the conducting layer component and a conductor wire in the power line is coated with the composite conducting element.

摘要： A charging system for an electric energy storage includes a cable assembly and a plug transition between the cable assembly and the electric energy storage. The cable assembly includes a cable provided with at least two separate power conductors and at least one earth conductor. The power conductors are spaced apart from each other within the cable, with each surrounding at least one tube and including a plurality of intertwisted wires stranded around the tube. The cable assembly also includes at least two separate cooling circuits within the cable, namely a first cooling circuit having a cooling fluid in the tubes surrounded by the power conductors, and a second cooling circuit having a cooling fluid in auxiliary tubes to cool the plug transition. Systems and methods are also provided for charging an electrical energy storage on basis of such a cable assembly.

摘要： A shielded electrical cable includes conductor sets extending along a length of the cable and spaced apart from each other along a width of the cable. First and second shielding films are disposed on opposite sides of the cable and include cover portions and pinched portions arranged such that, in transverse cross section, the cover portions of the films in combination substantially surround each conductor set. An adhesive layer bonds the shielding films together in the pinched portions of the cable. A transverse bending of the cable at a cable location of no more than 180 degrees over an inner radius of at most 2 mm causes a cable impedance of the selected insulated conductor proximate the cable location to vary by no more than 2 percent from an initial cable impedance measured at the cable location in an unbent configuration.

摘要： A device is used to sever an electrical power cable for the transmission of high voltage. The device includes a frame having first movable cutting blade carried thereon and second stationary cutting blades carried thereon. The blades can sever the electrical power cable upon movement of the first cutting blade relative to the frame. A sensor is provided and is configured to register a position of the first cutting blade relative to the frame. An evaluation and/or transmission controller is configured to receive information from the sensor and interrupt severing of the electrical power cable by the blades in response to the information.
