A charge-receiving layer for an e-paper assembly includes a plurality of conductive paths spaced apart throughout an insulative matrix, with each conductive path including at least one elongate pattern of conductive particles.

A crosslinked polymer composition based on a plastomer, which is suitable for producing at least one layer of cable accessories like cable joints, bushings or terminations; its use for preparing such a layer and the cable accessory comprising the composition.

The corona shield can be applied in electric machines in a faster manner by using radiation-cured materials.

The present disclosure is directed to laser-markable insulation material and cable or wire assemblies containing such insulation material. In certain embodiments, the laser-markable insulation material can include a fluoropolymer and an inorganic laser-markable pigment. The pigment can have a mean crystal size in a range of about 0.4 microns to about 2 microns and/or a median particle size (d.sub.50) in a range of about 0.45 microns to about 2 microns. The insulation material can exhibit improved initial and heat-aged contrast ratios without diminishing the ability of a cable or wire containing the insulation material to meet industry standards for electric-arc tracking and propagation resistance.

An assembly can include a housing that includes opposing ends, a longitudinal axis, an axial length defined between the opposing ends, a maximum transverse dimension that is less than the length and an interior space; circuitry disposed at least in part in the interior space; and a coated electrical conductor electrically coupled to the circuitry where the coated electrical conductor includes an electrical conductor that includes copper and a length defined by opposing ends, a polymeric electrical insulation layer disposed about at least a portion of the length of the electrical conductor, and a barrier layer disposed about at least a portion of the polymeric electrical insulation layer.

A thermally conductive insulator consisting essentially of a silicon nitride member, comprise: a first region provided 10 m or more away from a first surface of the member along a depth direction in a section vertical to the first surface and containing at least one substance selected from the group consisting of silicon carbide and a carbon material; and a second region provided between the first surface and the first region. A concentration of silicon nitride of the second region is higher than a concentration of silicon nitride of the first region.

A method for forming magnet wire with improved partial discharge performance may include providing a conductor, forming a first layer of polymeric enamel insulation formed around the conductor, and forming a second semi-conductive layer around the first layer. Forming the second layer may include providing a base polyamic acid and complexing filler particles with the base polyamic acid. The polyamic acid may be applied around the first layer, and the filler particles may migrate towards an outer surface of the second layer. The polyamic acid may be cured to form a semi-conductive enamel layer, and at least sixty percent by weight of the filler particles may be positioned within an outer half of the second layer following the migration.

The invention is related to a continuous system for coating carbon fibre materials and a device developed to carry out the method. The coating of carbon fibre with both an electrochemical method following the polymerization (polyethylenedioxythiophene, polypyrrole, polythiophene, polyaniline and derivates thereof) of the monomer of conductive polymer and coating with an insulating sizing material (thickening material) is carried out in a single step.

A composition for manufacturing a crosslinked ethylene tetrafluoroethylene (ETFE) copolymer with enhanced abrasion resistance and heat resistance is provided, the composition including ETFE, about 0.1-10% w/w of a metal oxide that effectively scavenges high levels of fluoride ions; and a crosslinking agent. Methods of using and making the composition are also provided.

The corona shield can be applied in electric machines in a faster manner by using radiation-cured materials.
