Synthetic fibre electrical insulator sheets - of wet laid sheets of synthetic fibres, e.g. of poly-(meta)-phenylene isophthalamide and fibrids of aromatic bisphenol polyester as binder

Insulating sheets are composed of a paper contg. 20-80 wt. % short synthetic fibres and 80-20 wt. % of a thermally stable fibrous binder comprises of 70-100% fibrids of aromatic polyesters with a softening points of 185-340 degrees C, made from aromatic bisphenol and aromatic dicarboxylic acids. The sheets have high dielectric strength and are useful as insulating sheets in electrical machinery, transformers, cables and coverings. The sheets can be bent even in relatively thick sections (e.g. 0.7-0.8 mm) and retain the shape well. The synthetic fibres may be e.g. of poly-m-phenyleneisophthalamide, polydiphenylene 4,4'-sulphone-terephthalamide, polyoxadiazole and polyethylene terephthalate. Suitably 70% of the binder is made up of the aromatic bisphenol/aromatic dicarboxylic acid (co)polyester, opt. together with up to 30% other binder fibres, esp. cotton cellulose, added to improve the regularity of formation of the paper.

A cellulose material contains cellulose fibers having an impregnation. Accordingly, the impregnation is made of nanoparticles, in particular BNNT, containing a shell of polymers, in particular PEDOT:PSS. The impregnation forms a type of network that can reduce the specific resistance of the cellulose material due to the electrical conductivity of the network. The cellulose material can thereby be advantageously adapted to corresponding applications with respect to the electrical properties thereof. The cellulose material can thus also be used to electrically insulate transformers, wherein the cellulose material is thereby saturated with transformer oil and an adaptation of the specific resistance of the cellulose material to the specific resistance of the oil leads to improved dielectric strength of the transformer insulation. A method for producing the cellulose material described above contains a suitable impregnation step for the cellulose material.

Composite coil insulation - with resinous insulation, porous sheath and synthetic surface conducting layer

The windings of electrical machines are provided with a preformed porous insulating sheath which is pretreated with a flexible electrically conducting coating, and are impregnated with an insulating thermosetting resin after the sheath has been placed in position. The flexible conducting layer provides an equipotential surface for stators of high voltage generators and an impervious layer preventing electrical dishcharges due to inclusion of air pockets and uneven expansion of the impregnant. The porous sheath may be of e.g. paper and silicone resin which is flexible and rendered conductive by inclusion of e.g. graphite, is used to coat it before vacuum impregnation of the windings with thermosetting resin after placing the sheath in position.

The tape or folium is used for finishing coils and windings to protect and locate the winding wires during subsequent operations including dipping. It consists of an open woven, needled, or matted material, porous to normal impregnating varnishes, which on one side only has strips or points of self adhesive material applied to it. The adhesive matter covers not more than 50% of the surface area of the one side, and may be protected by a sacrifice layer before use. As the material thus remains mainly porous satisfactory impregnation can be achieved. The material can be wound with spacing or as overlapping layers.
