An object of the present invention is to provide a resin composition having excellent heat resistance and excellent thermal adhesiveness, so as to provide an electric insulating sheet having excellent heat resistance. In order to achieve the aforementioned object, the present invention provides a resin composition which contains a polyether sulfone resin and a resin having a specific melt viscosity, and contains at least a phenoxy resin other than the polyether sulfone resin.

Resin composition and electric insulating sheet

There is provided insulating paper for oil-immersed motors used in an oil-immersed motor in a state where folding is applied to the paper, the motor operating in a state where it is immersed in a cooling oil, the paper including a polyester film and heat resistant sheets made from aromatic polyamide laminated to both front and back surfaces of the polyester film, the polyester film and the heat resistant sheets being bonded with an acrylic adhesive, wherein the acrylic adhesive contains polyisocyanate and a polybutyl acrylate having a weight average molecular weight of 400,000 or more in a proportion of the polyisocyanate of more than 3 parts by weight and 20 parts by weight or less based on 100 parts by weight of the polybutyl acrylate.

Insulating paper for oil-immersed motors

An interphase insulating member allowing reduction in size of a rotating electric machine is provided. The interphase insulating member includes a flat portion interposed between and insulating neighboring two phases of coil ends, and a three-dimensional portion protruding from the flat portion and guiding the coil. On a surface of the flat portion, epoxy resin layer is provided as a reinforcing member.

Interphase insulating member and rotating electric machine

An insulation inspection apparatus includes a chamber in which a stator with a winding can be stored, an electrode movable along the outer circumference of a coil end of the stator winding, a voltage application unit applying voltage between the coil end and electrode, a sensor unit sensing leakage current and/or voltage drop between the coil end and electrode, and a pressure reduction unit reducing the pressure in the chamber.
