A coating composition for coating of components of a flow machine, especially a turbomachine such as a gas turbine with compressor, or of a compressor, which are exposed to the fluid stream of the flow machine or of the compressor, wherein the coating composition includes anticorrosion pigments, wherein the coating composition includes hard material particles, and wherein the coating composition is an RT-curing, UV-curing and/or thermally curing coating composition. A component of a flow machine or of a compressor has the coating composition. A method of maintaining a flow machine or a compressor uses the coating composition.

High-voltage insulation systems are simplified and can have a thinner design by the use of an external corona shielding system that may include an electrically conductive PTFE fabric. Thermal conductivity may also be improved.

Material for insulation system, insulation system, external corona shield and an electric machine

An anhydride-free impregnating resin for an electrical insulation body, the impregnating resin has an epoxy resin, a curing agent and nanoscale and/or microscale inorganic particles. An impregnable electrical insulating tape for an electrical insulation body has a curing agent applied to the electrical insulating tape. A method includes producing an electrical insulation body An electrical insulation body includes an anhydride-free impregnating resin, where the impregnating resin has an epoxy resin, a curing agent and nanoscale and/or microscale inorganic particles.

Storage-stable impregnating resins and electrical insulating tapes

By using an electrically conductive PTFE fabric, high-voltage insulation systems are simplified and can be made thinner, also improving the thermal conductivity. The insulation material is in two layers, each with a hydrophobic and a hydrophobic region, and the hydrophobic regions of the layers are opposed.

An impregnating resin for an electrical insulation body includes a base resin, a filler having nanoscale particles, and a radically polymerizing reactive diluent. The impregnating resin includes a crosslinker for crosslinking the base resin and the reactive diluents. The base resin is an epoxy resin. An electrical insulation body includes the impregnating resin and a method produces the electrical insulation body by production of an impregnating resin having a base resin, a filler having nanosize particles and a free-radically polymerizing reactive diluent.

Fewer insulation layers can be used by virtue of using hydrophobic electrically conductive materials around a main insulation around a conductive bar. There are several more layers of conductive and/or non-conductive material.

Winding layers composed of different materials

An external corona shielding for a conductor bar of an electric machine, a main insulating layer sheath on the conductor bar. The shielding has a first ply, which sheaths the main insulating layer, and a second ply, which sheaths the first ply. Each ply is a conductive, impregnatable layer with a sliding layer, wherein the sliding layers of the two plies () face one another. Each sliding layer has at least one cutout, wherein the two conductive layers are connected to one another through these cutouts with the aid of a permanently elastic, electrically conductive connection.
