A communications cable is described. The communications cable can include a cable jacket, a separator structure that defines one or more channels for receiving at least one communications medium, and an insulator that surrounds the communications medium. The cable jacket can include one or more corrugations on at least one of its interior or exterior surfaces. The separator can also include one or more grooves on at least a portion of its surface. The insulator can also include one or more indentations on at least one of its interior or exterior surfaces. The corrugations, grooves, and indentations can extend along the longitudinal length of the cable and define one or more air channels for forwarding and circulating air through or on the surface the cable. The circulation of air in the cable can reduce the temperature of the cable and increase the quality of the signal transmitted through the cable.

The present disclosure relates to a telecommunications cable. The telecommunications cable includes a plurality of twisted pairs of insulated conductors. The plurality of twisted pairs of insulated conductors extends substantially along a longitudinal axis of the telecommunications cable. In addition, the telecommunications cable includes a separator. The separator separates each twisted pair of insulated conductor of the plurality of twisted pairs of insulated conductors. Moreover, the telecommunications cable includes a first layer. The first layer surrounds the separator and the plurality of twisted pairs of insulated conductors along a length of the telecommunications cable. The separator is I-shaped filler. The separator is made of low smoke zero halogen material or MDPE. The first layer is made of low smoke zero halogen material, polyethylene or poly vinyl chloride. The first layer has a thickness in a range of about 0.4 millimeter-2.5 millimeters.

One aspect of the present disclosure relates to a system for chronic neural recording from conscious, freely-moving subjects. The system can reduce or eliminate noise effects (due to triboelectric noise and audiophonic noise) during the chronic recording of low amplitude neural signals. The triboelectric noise effects can be reduced or eliminated by using in implant lead designed with insulating materials with charge affinities separated by 10 nC/J or less. The recording device can include a preamplifier device that uses capacitors with a low-distortion dielectric material.

The present disclosure relates to an insulated conductor for a telecommunications cable. The insulated conductor includes a first surface surrounding a core region of the notched conductor. The first surface defines a plurality of grooves extending radially inward towards the second longitudinal axis of the insulated conductor. Each of the plurality of grooves comprises of a first groove area section and a second groove area section. The first groove area section and the second groove area section are in continuous contact. The insulated conductor includes an insulation layer circumferentially surrounding the conductor. The insulated conductor has a first diameter in a range of about 0.5 millimeters to 0.65 millimeters. The telecommunications cable includes, plurality of twisted pairs of insulated conductors, a separator and a cable jacket.

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.

A signal cable structure includes a set of strands, an outer insulation tube and a water swellable powder. The set of strands includes a plurality of twisted pairs. The twisted pairs are enclosed to form a center portion, and each of the twisted pairs includes two wires intertwined with each other. The outer insulation tube sheaths the set of strands; an outer ring portion is surrounded outside the set of strands and formed between the outer insulation tube and the set of strands. The water swellable powder is distributed in the outer ring portion, and the center portion of the set of strands is not distributed with the water swellable powder. Thereby, a signal cable with waterproof performance is provided.

A cable separator comprising a preshaped article having a longitudinal length, wherein said preshaped article is substantially entirely formed of a foamed polymer material having a glass transition temperature greater than 160 C. and being halogen-free is provided.
