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 no load regulation (can be customized load regulation) 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.
