Technology tó pẹ́ jù

• 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.

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.
