_{Product advantage}
...

Leading technology
- High pressure copper tape 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 short circuit resistance
- Iron core 45° full oblique joint step laminated structure

The shell
- Mitsubishi laser cutting machine and CNC punching, reducing, folding and other equipment to ensure the accuracy of processing
- ABB robot automatic welding, laser detection, to avoid leakage, qualified rate of 99.99998%
- Electrostatic spray treatment, 50 years of paint (coating corrosion resistance within 100h, hardness ≥0.4)
- Fully sealed structure, maintenance-free and maintenance-free, normal operation life of more than 30 years

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

winding
- Low voltage winding is made of high quality copper foil, excellent insulation resistance
- The high voltage windings are usually made of insulated copper wire, using the patented technology of Hengfengyou Electric
- Very good resistance to radial stress caused by short circuit

High quality material
- Baosteel, Wisco production of silicon steel sheet
- High quality anaerobic copper from China
- CNPC (Kunlun Petroleum) High quality transformer oil (25# 40#)

Other instructions
- The low-voltage outgoing terminal is tinned copper bar
- The high-voltage outlet terminals are ring tinned bolts
- Default no-load voltage regulation (on-load voltage regulation can be customized) Tap switch 5 or 7 speed adjustment
- Transformers above 630KVA are protected by gas relays

Patent technology
- Thanks to hengfengyou electric "ultra-low loss energy saving power transformer" patent technology, can realize 5% material saving, transformer loss than similar products in the market reduced 10-20%, more energy saving and environmental protection.
