To wound a power transformer must have a certain understanding of the materials related to the mains transformer, and to this end we must know some of the material on the production of power rheostat,You can check out www.mainstransformer.com for more detail. First, the core material used by the power transformer core material mainly iron piece, low silicon, high silicon, a conductive steel added silicon can reduce the steel sheet to increase the resistivity, it can reduce the eddy current, so that reduce its loss. We often referred added the quality of the silicon steel sheet of the silicon steel sheets used for the silicon steel sheet, the quality of the power transformer has a great relationship, the quality of the silicon steel sheet is usually the magnetic flux density B, said general Heitie sheet B value 6000-8000, low silicon 9000-11000, high silicon 12000-16000 Second, the wound power transformer is usually a material enameled yarn package line, silk envelope, the most commonly used enameled wire. For the requirements of the wire is good conductive properties, an insulating lacquer layer has sufficient heat resistance, and have a certain corrosion resistance. QZ Model under normal circumstances, is preferably a high-strength polyester enameled wire. Third, the insulating material in the wound transformer coil frame interlayer isolation around the resistive isolation between the insulating material to be used, the general power transformer frame material can be used phenolic cardboard, polyester film available telephone or paper interlayer as isolated, winding between available yellow wax cloth for isolation. Fourth, the impregnated material power transformer winding, but also over the last step is impregnated with insulating paint, it can enhance the mechanical strength of the power transformer to improve the insulation performance and extend the life of cresol varnish can be used, under normal circumstances, as the impregnated material. Do not know everyone what materials can help supplement?
