Product overview
-Hengfengyou Electric is a professional manufacturer of distribution transformers with 30 years of manufacturing experience.
-The single-phase Pole-Mounted transformers designed and produced are usually used for urban and rural power distribution
-Input voltages：11kv, 12.4kv, 13.2kv, 13.8kv and 34.5kv; Output voltage：240 / 480v, 120 / 240V, etc.
Product advantages
> Leading technology
- Unique winding technology improves lightning resistance.
- Small magnetic leakage, high mechanical strength, strong resistance to short circuit.
- Iron 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)
- Cylindrical fully sealed structure, equipped with self-sealing pressure relief valve
- Transformer upper and lower support pendant is manufactured according to ANSI standard
- Fully 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.
> Winding
- The low-voltage winding is wound with high quality cable paper.
- The high voltage winding is made of high quality polyurethane enamelled round copper wire.
- Insulation between layers is made of dotting paper to bond the coil into a fixed unit, which has excellent insulation resistance
- The transformer structure is reliable in normal operation and transportation.
> High quality material
- Baosteel and WISCO produce silicon steel sheets
- China's high quality oxygen free copper
- CNPC (Kunlun Petroleum) High quality transformer Mineraloil (25#) or FR3 Oil
> Other
- High and low pressure porcelain bushing with ring - type copper tin - plated terminal.
- The earthing terminal of the box is ring bolt.
- Install finite current fuses and arresters.
Working conditions
- Altitude less than 2000m, air temperature -25℃~45℃, humidity less than 90% (+25℃)
- In the place without severe vibration, the outdoor wind speed shall not exceed 35m/s
- No gas or conductive dust that seriously affects the insulation of the transformer;No explosion hazard, no corrosion of electrical components
- If the above normal operating environment conditions are exceeded, customers can customize the solution with our company separately
