Product Description




Qingdao HengFengYou Electrical Engineering Co. LTD., aka HFY Electrical Engineering, is a Chinese leading manufacturer and supplier in electricity transmission and distribution industry.

Our main market covers medium voltage, high voltage and ultra-high voltage power distribution. In the past few years, we had annual output of 100 million US dollars. The best-seller of our products is oil-immersed transformer series, which are designed with efficiency, energy saving and performance in mind. Our other products are also well known and often seen in projects, such as dry-type transformer series, switchgear cabinet, box-type substation, high-voltage vacuum circuit breaker on columns.

35 KV oil immersed transformer

Compared 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 measures to prevent oil leakage.

·Structural features:

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.
