Product advantages

Leading technology

  • High pressure copper tape winding technology, flame retardant formula vacuum pouring.

  • Low pressure copper foil winding technology, thermosetting epoxy prepreg cloth insulation.

  • High quality iron core 45° full oblique joint step laminated structure.

The iron core

  • The core is made of high quality cold rolled grain oriented silicon steel sheet insulated by mineral oxide.

  • Minimize loss level, no-load current and noise by controlling the cutting and stacking process of silicon steel sheet.

  • Apply class F or CLASS H core paint on the surface of assembled cores to prevent corrosion and rust.

Low voltage winding

  • The low voltage winding is made of high quality copper foil.

  • Insulated by thermosetting epoxy preimpregnated cloth.

  • Winding ends are insulated with thermosetting epoxy preimpregnated cloth.

  • Excellent insulation resistance.

  • Very good resistance to radial stress caused by short circuit.

  • The outgoing terminal of the low-voltage winding is tinned copper bar.

  • The whole winding is heated in the oven to 140°C and polymerized for 4 hours. It has excellent corrosion resistance of industrial gas.

High voltage winding

  • Made of insulated copper wire and using the patented technology of Hengfengyou Electric.

  • For small volume products, the high voltage winding uses a linear voltage gradient from top to bottom.

  • For products with large capacity, the high voltage winding is made by "tape winding" technology.

  • The application of these methods makes the electric field between adjacent conductors very low.

  • Transformer structure is reliable during normal operation and transportation.

High quality material

  • Baowu Steel Group production of silicon steel sheet.

  • China produces high quality anaerobic copper.

  • Huntsman Epoxy resin (including flame retardant filler).

What is the epoxy casting process for the windings and core z of the transformer?

Manufacture of Windings and Iron Cores:

Windings Manufacture:

  • Use a wire winding machine to wind the copper wires into the required shapes and number of layers.

  • Ensure the uniformity and compactness of the windings.

  • Add insulating materials, such as insulating paper or insulating tape, between each layer of copper wires.

Iron Core Manufacture:

  • Use a silicon steel sheet laminating device to laminate the silicon steel sheets into an iron core.

  • Ensure the flatness and compactness of the iron core.

  • Conduct necessary pre-treatments on the iron core, such as deburring and cleaning.

Assembly:

Assembling Windings and Iron Cores:

  • Assemble the windings and the iron core together, ensuring the correct positions and connections between them.

  • Use temporary fixing devices (such as clamps) to fix the windings and the iron core to prevent displacement during the casting process.
