Produktbeschreibung

_{31.5MVA 110KV/22KV Wholesale and retail factory price factory direct sales price three-phase large power transformer}

_{product introduction
...}

>Power transformer is main primary equipment in power grid, especially on long distance transf-ormation.

 

>General type is used for up and down voltage ,auto transformer is used for coupling power system with different voltage level.

 

>There are various types power transformer such as double winding, triple winding, off circuit tap change, on load tap change, high impedance.

 

>Apply to grid power station, hydropower station, thermal power plant, industrial power station and soon.

 

>HENGFENGYOU ELECTRIC using high purity copper winding, Bao-steel high performance CRGO four stages lamination, loss level could better than GB and IEC standard.

 

>Using processes like tension plate, cushion block precompression, outside and inside gagger to guarantee performance of loss level, dynamic stability, heat stability, and noise level.

 

>Nice appearance with bending corrugated bell jar type oil box.

_{Product advantage}
...
 

> Leading technology
- High voltage copper strip winding technology, improve lightning resistance
- Low voltage copper foil winding technology, high quality A class insulation material insulation
- Small magnetic leakage, high mechanical strength, strong resistance to short circuit
- Core 45° fully oblique joint stepping laminated structure

> The shell
- Japanese mitsubishi laser cutting machine and numerical control punching, reducing, folding and other equipment to ensure the accuracy of processing
- ABB robot automatic welding, laser detection, to avoid leakage, pass rate of 99.99998%
- Electrostatic plastic spray treatment, 50 years do not take off the paint (coating corrosion resistance within 100h, hardness ≥0.4)
- Sealed structure, maintenance-free, normal operation life of more than 30 years

> The iron core
- The iron core is made of high quality cold-rolled grain oriented silicon steel sheet with mineral oxide insulation (from Baosteel and WISCO of China).
- By controlling the cutting and stacking process of silicon steel sheet, the loss level, no-load current and noise can be minimized
- The iron core is specially reinforced to ensure the structure of the transformer is firm during normal operation and transportation

> Winding
- The low voltage winding is made of high quality copper foil with excellent insulation resistance
- The high-voltage winding is usually wound with insulated copper wire, using the technology patented by hengfengyou electric
- It has very good ability to bear radial stress caused by short circuit

> High quality material
- Baosteel and WISCO produce silicon steel sheets
- China's high quality oxygen free copper
- CNPC (Kunlun Petroleum) High quality transformer oil (25#)

> Other Notes
- The low voltage outlet terminal is tin-plated copper bar
- High voltage outlet terminals are ring - type tin-plated bolts
- Default NLTC (no Load tap changer) ,OLTC(on load tap changer) can be customized.Tap switch 5 or 7 adjustment

- Transformers above 630KVA are equipped with gas relay protection

> Patent technology
- Thanks to the patented technology of "ultra-low loss energy-saving power transformer" of Hengfengyou Electric, the material can be saved by 5%, and the loss of the transformer can be reduced by 10-20% compared with similar products in the market, which is more energy saving and environmental protection.
