Product Description

Oil Immersed Power Transformer 4000kVA 35kv Three Phase Two Winding Oltc

35kv Three Phase Oil-immersed Transformer
Product introductionCompared with S9 series, the no-load loss of S11 series products is reduced by 30% on average, and no-load current is 70-80% lower. The iron core is made of import high magnetic conductivity, low loss, cold-rolled high-quality silicon steel sheet, which reduces the no-load loss and saves energy significantly. It shows characteristics of high safety and reliability, advanced structure, small dimension, light weight, low noise, low temperature rise, anti-corrosion and reliable anti-leakage measuresto prevent oil leakage.

Product advantages

1. The low-voltage winding is made of full-section copper foil and by special low-voltage winding machine with f-grade insulation.
2. The winding end is sealed and casted with resin, and then shaped by curing to prevent moisture and fouling.
3. Temperature control device: the transformer is equipped with BWDK series signal thermometer, which is embedded in the upper part of the low-voltage coil.The temperature-measuring components can automatically detect and display the working temperature of the corresponding phase coil, and alarm and trip at over temperature .
4. Insulation grade: the insulation grade of transformer can be divided into grades.

Conditions of use

1. The maximum ambient air temperature shall not exceed 40°C, and the minimum shall not below -25°C;
2. The altitude shall not exceed 1000m. If special customized transformers and low-voltage components are used, the altitude can reach 4,000m;
3. The vertical inclination is no more than 5°, and no violent vibration and impact;
4. The air humidity is not more than 90% (25°C);
5. No gas and conductive dust that will seriously affect the insulation of transformer,no explosion hazard and corrosion of electrical components;
6. Outdoor wind speed shall not exceed 35m/s;
7. If service conditions beyond the above, specially customized product is available.
