• The reel core fully sealed distribution transformer is a new generation of low noise and low loss transformer developed in recent years. Its iron core has no joint, greatly reduces the no-load loss and no-load current, reduces the no-load current by 60%~80%, the high and low coils are continuously coiled on the core column, the winding is tight, the concentricity is good, and the product is enhanced more. Anti-theft performance. The noise decreased by more than 10 decibels. The temperature rise is low 16-20K. Because of the continuous winding of iron core (cross section is pure circle), the orientation loss of silicon steel sheet is fully utilized, and the no-load loss is reduced by 20%~30%.

• The low voltage winding with capacity in the 630~2500kVA enclosure is made of cylinder or spiral structure with high mechanical strength and balanced ampere distribution. The product has good short circuit resistance.

• The positioning structure is added to the body so that it does not produce displacement during the transportation process, and all fasteners are equipped with fastener nuts to ensure that the fasteners are not loose during the long run of the product and meet the requirements of the non core lifting.

• The product surface is painted, primed and topcoat after degreasing, rust removing and phosphating. It can meet the special requirements of metallurgy, petrochemical system and wet dirty area.This series of products has beautiful appearance, small size, and can reduce the installation area. It is an ideal free maintenance quality product.

_{Product features}
...

<sub>> 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.
