A cable includes a pair of insulation core wires, a shielding layer and an air accommodating cavity. The pair of insulation core wires extend longitudinally parallel to each other. Each of the insulation core wires has a central conductor and a core wire insulation layer wrapped around the central conductor. The shielding layer is wrapped outside the pair of insulation core wires. The air accommodating cavity is formed between the core wire insulation layers of the pair of insulation core wires and the shielding layer, and is adapted to accommodate air.

A device is provided with a PWM signal generating circuit, a gate driver and a transmission line connecting them. The transmission line transmits a PWM signal output from the PWM generator as an input signal for the gate driver. A noise suppression member is provided to at least a part of a periphery of the transmission line. The noise suppression member has a structure that magnetic powder is dispersed in a binder and has an imaginary part of a complex magnetic permeability that is greater than or equal to 5 and smaller than or equal to 30 in a range of 500 MHz to 3 GHz. The noise suppression member has a thickness t greater than or equal to 20 m. The noise suppression member is disposed apart from a conducting wire of the transmission line by a distance greater than 0.05 mm or smaller than or equal to 5 mm.

A cable includes a first twisted pair of insulated conductors, a second twisted pair of insulated conductors, a shielding tape, and an outer jacket surrounding the first twisted pair of insulated conductors, the second twisted pair of insulated conductors and the shielding tape. The shielding tape includes a substrate and a plurality of conductive shielding segments. The plurality of conductive shielding segments is disposed on the substrate. Each conductive shielding segment is spaced from each immediately adjacent conductive shielding segment in a longitudinal direction.

A cable may include a plurality of twisted pairs of individually insulated conductors, a separator positioned between the twisted pairs, and a jacket formed around the twisted pairs and the separator. The separator may include a longitudinally extending spine positioned between the plurality of twisted pairs and a plurality of projections extending from the spine. Each projection may extend between at least one adjacent set of twisted pairs. Further, along a longitudinal length of the separator, the plurality of projections extend between all of the adjacent sets of twisted pairs. However, at any given cross-sectional point along the longitudinal length, the separator does not extend between all of the adjacent sets of twisted pairs.
