Product features
...
> Leading technology
- High pressure copper strip winding technology, flame retardant formula vacuum pouring
- Low pressure copper foil winding technology, thermosetting epoxy prepreg cloth insulation
- High quality iron core 45° fully oblique joint step laminated structure
> The iron core
- The core is made of high quality cold-rolled grain oriented silicon steel sheet with mineral oxide insulation
- By controlling the cutting and stacking process of silicon steel sheet, the loss level, no-load current and noise can be minimized
- The surface of the assembled core is sealed with grade F or grade H core paint to prevent dust and corrosion
> Low voltage winding
- The low voltage winding is made of high quality copper foil
- The insulation between layers is made of thermosetting epoxy prepreg cloth
- The ends of the windings are insulated with thermosetting epoxy prepreg cloth
- Excellent insulation resistance
- It has very good ability to bear radial stress caused by short circuit
- The outlet terminal of low voltage winding is tin-plated copper bar
- The whole winding is placed in the oven and heated to 140°C. After 4 hours of polymerization, it has excellent corrosion resistance to industrial gases
> High voltage winding
- Woven with insulated copper wire, and applied by hengfengyou electric exclusive patent technology
- For small volumes, the high voltage winding uses a linear voltage gradient from top to bottom
- For large-capacity products, the high-voltage windings are wound by "band winding" technology
- The application of these methods causes the electric field between adjacent conductors to be very low
- The transformer has a firm structure during normal operation and transportation
> High quality material
- Baosteel, WISCO silicon steel sheet
- China produces high quality oxygen free copper
- Swiss Huntsman epoxy resin (with flame retardant filler)
> Patent technology
- The high pressure coil is cast under high vacuum, and the casting material system is added with a unique flame retardant filler, which is a patented technology of Hengfengyou Electric.When the transformer is exposed to the flame, the transformer will die out immediately.With a unique and excellent flame retardant characteristics and the ability to adapt to harsh working environment.
