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
The winding of the core material belt is completed by a special winding machine, which can automatically tilt 30° accurately while winding
Stereo triangle coil core transformer has 10KV and 20KV two kinds of voltage compatible product series
> The shell
Japanese mitsubishi laser cutting machine and numerical control punching, reducing, folding and other equipment to ensure the accuracy of processing
ABB robot internal and external double layer welding, laser detection, to avoid leakage, pass rate of 99.99998%
Electrostatic plastic spray treatment, 30 years 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).
The three-phase magnetic circuit has no joint, and the direction of magnetic flux is exactly the same as the orientation of silicon steel sheet crystal, which greatly reduces the no-load loss, no-load current and noise
The cores are rolled on the production line, without cross-cutting equipment, and the quality fluctuation caused by manual lamination, lamination and disassembly of the yoke is eliminated
> Winding
The low-voltage winding is made of high quality copper foil (customized aluminum foil) with excellent insulation resistance
The high-voltage winding is usually wound with insulated copper wire (customizable aluminum 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# 40#)
> Other Notes
The low voltage outlet terminal is tin-plated copper bar
High voltage outlet terminals are ring - type tin-plated bolts
Default no load regulation (can be customized load regulation) tap switch 5 or 7 adjustment
Transformer above 800KVA is equipped with gas relay protection, with oil temperature overheating alarm tripping protection, light gas alarm prompt, heavy gas tripping protection function
> 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.
"Multi-layer brush type stacking end ring", patented technology, greatly improve the resistance to short circuit winding;
The electrical performance of the transformer has reached the Chinese national standard GB and IEC standards, with high efficiency and low loss characteristics
