...
Three phase transformer
Ultra-low loss energy saving and environmental protection type
High permeability
Low losses
Low iron losses
QSG/SG three-phase dry type isolation transformer is a new generation energy-saving power transformer developed by our factory based on international similar products and combined with China's national conditions, from 300VA to 1600KVA, in line with international and national standards such as IEC439 and GB5226. The winding adopts the method of winding out the hole row. The transformer is vacuum-impregnated, so that the insulation grade of the transformer reaches F class or H class, and the product performance reaches the advanced level at home and abroad. QSG/SG series three phase dry type isolation transformer is widely used in circuits with AC 50Hz to 60Hz and voltage below 2000V. all can be specially customized as per different requirements of the end users. -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
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.
