A carbon nanotube (CNT) cable includes a pair of plated twisted wires, wherein each wire includes one or more sub-cores, wherein at least one sub-core includes CNT yarn; a dielectric surrounding the plated twisted wires; and an electrical layer surrounding the dielectric, wherein the electrical layer is configured to shield the CNT cable. A method for making a CNT cable includes the steps of controlling a deposition rate, depositing plating so as to surround a pair of wires, wherein each wire includes one or more sub-cores, wherein at least one sub-core includes CNT yarn, twisting the plated wires together, and surrounding the plated twisted wires with an electrical layer configured to shield the plated twisted wires, thereby creating the CNT cable.

An electrical cable includes a conductor assembly having a first conductor, a second conductor and an insulator surrounding the first conductor and the second conductor. The insulator has an outer surface having an RMS roughness of less than 1.0 micrometers. A cable shield provides electrical shielding for the first and second conductors and has a metallized conductive layer on the outer surface of the insulator. A method of manufacturing an electrical cable includes feeding a first conductor and a second conductor to a core extruder, extruding an insulator around the first and second conductors at the core extruder, heating an outer surface of the insulator to lower a roughness profile of the outer surface, and directly apply a conductive layer to the outer surface of the insulator.

A parallel pair cable includes a pair of metal wires aligned in parallel at a predetermined interval, an insulating resin configured to integrally cover the pair of metal wires and having a cross-sectional shape of an ellipse, and a shield layer provided on an outer periphery of the insulating resin. The shield layer is a layer formed by plating or vapor-depositing metal on an outer peripheral surface of the insulating resin.

A differential signal transmission cable includes an insulation layer extending in a longitudinal direction of the differential signal transmission cable, a pair of signal lines extending in the longitudinal direction and buried inside the insulation layer, an intermediate layer covering an outer circumferential surface of the insulation layer, a shield, and catalyst particles. The shield includes an electroless plating layer covering an outer circumferential surface of the intermediate layer. The catalyst particles are dispersed between the intermediate layer and the electroless plating layer.

An electrical feedthrough includes a base body with a sealing region, at least one opening and an electrical conductor fed through the opening, wherein the conductor is held in the opening by a fixing material and the fixing material seals the opening. The edges which surround the opening are designed to be sharp and all edges of an outer contour of the base body are provided with a chamfer or a rounding, which has a size or a radius r in the range of 0.3 mm to 2 mm.
