摘要:
The present invention is directed to high temperature performance filled polyimide materials useful for high power density applications having good ultra high thermal properties. A high temperature dielectric film is disclosed comprising an aromatic polyimide formed by a solution polycondensation reaction and a passivated nanoparticulate ceramic oxide dispersed within the aromatic polyimide. The ceramic oxide nanoparticles are comprised of a monofunctional organosilane covalently attached to the surface of the ceramic oxide nanoparticles.

A corona resistant high voltage bushing assembly includes an insulating sleeve to surround a conductor, a flange located on an outside surface of the insulating sleeve, and a first band of semiconductive glaze located on the outer surface of the insulating sleeve spaced apart from an end of the insulating sleeve.
摘要:
A thermoplastic composition includes particular amounts of a poly(arylene ether), a hydrogenated block copolymer, a copolymer of ethylene and an alpha-olefin, a plasticizer, a white pigment, and an ultraviolet radiation stabilizer. The composition exhibits excellent light stability, and it is particularly useful for forming white or off-white cable insulation.

A high voltage bushing assembly includes an insulating sleeve which is made of high strength alumina porcelain to surround a conductor, a flange located on an outside surface of the insulating sleeve, and a band of semiconductive glaze located on the outer surface of the insulating sleeve spaced apart from an end of the insulating sleeve.
摘要:
In one embodiment, a system includes a generator configured to receive a flow of an organic working fluid. The generator includes a stator and a permanent magnet rotor configured to rotate within the stator to generate electricity. The generator further includes one or more components disposed within the generator and configured to be exposed to the flow of the organic working fluid. The one or more components each include an underlying component and a varnish configured to withstand exposure to the organic working fluid to inhibit contact between the underlying component and the organic working fluid.

摘要:
A high voltage bushing assembly includes an insulator shell adapted to enclose an electrical conductor. An annular flange is slidably received over the insulator shell, the annular sleeve formed with a radially outwardly directed flange at an upper end and a radially inwardly directed flange at a lower end, with a sleeve portion extending axially therebetween. The insulator shell has an outside diameter and the sleeve portion has an inside diameter sized to create an annular, radial gap therebetween filled with a high thermal endurance fiberglass-reinforced epoxy resin.
