Benefits

High-quality Materials and Craftsmanship

Iron Core: Imported high-quality cold-rolled silicon steel sheets are selected, employing a fully inclined joint structure. The core column is bound with F-grade non-woven tape, and the iron core surface is sealed with insulating resin paint to prevent moisture and rust, thus reducing no-load loss, no-load current, and iron core noise. The clamps and fasteners undergo special surface treatment, enhancing the product's appearance and quality.
High-voltage winding: Utilizing vacuum pressure impregnation with epoxy resin and filler, significantly reducing partial discharge and enhancing the electrical strength of the coil. Both the inner and outer walls of the winding are filled with fiberglass mesh plates, strengthening the mechanical integrity of the coil and increasing the product's ability to withstand sudden short circuits, ensuring the winding will never crack.
Low-voltage winding: Employing a foil-type structure to solve the problem of axial spiral angle when winding with wire, ensuring a more balanced turn-to-turn voltage. Simultaneously, the coil adopts axial cooling ducts to enhance heat dissipation.DMD epoxy resin pre-impregnated tape is used between winding layers, enabling overall solidification and shaping.
Temperature Control System and Air Cooling System: Utilizing cross-flow top-blowing cooling fans, which feature low noise, high wind pressure, and an aesthetically pleasing appearance, enhancing the transformer's overload capacity. The temperature control is achieved through an intelligent temperature controller, improving the operational safety and reliability of the transformer.
Manufacturing Process: The coils are wound on a high-precision winding machine, and the low-voltage winding adopts a foil-type winding structure. When the transformer capacity is large, a ventilation duct is utilized. After the winding process is completed, vacuum drying is performed. The entire casting and curing process is strictly operated in accordance with the process requirements, with all processes requiring rigorous monitoring and adjustments as necessary. The precision casting process ensures that the coils are free from air bubbles and voids, resulting in the production of high-quality transformers.
