Is Enameled Wire Commonly Used for Winding Transformers?

  • Materials commonly used for winding transformers: Enameled Wire(XINYU), yarn covered wire, wire covered wire and paper covered wire. The requirements for conducting wires are good conductivity, sufficient heat resistance of insulating paint layer and certain corrosion resistance.

    The main components of the transformer are iron core and coil, and the others are accessories.

    Iron core materials: The iron core materials used in transformers mainly include iron sheet, low silicon sheet and high silicon sheet.

    Insulation material: In winding transformer, insulation material shall be used for insulation between coil frame layers and winding resistance. General transformer frame materials can be made of phenolic cardboard, epoxy board and cardboard.

    Impregnating material: after winding the transformer, there is another process, namely impregnating insulating paint, which can enhance the mechanical strength of the transformer, improve the insulating performance and prolong the service life. in general, cresol varnish can be used as impregnating material or 1032 insulating paint, resin paint.
