SC(B)10 Dry Type China Electrical Transformer Manufacturers Power Electrical Transformer For Sale From China

Dry type SC(B)11, SC(B)10, SC(B)9 distribution transformer is widely used for power supply & distribution in industrial and civil occasions, to step down grid voltage (6-35KV) to line voltage 400V. The transformers are resin insulated, which is safe, non-pollute, flame proof and can be installed directly on the load centre, with the merits of free maintenance, easy installation, low operation cost, low loss and excellent humidity resistance.

Main application in: High-rise buildings, airports, terminals, power plants, transformer stations, residential areas or packages of various sites.

Structural Features

1. Ultra low loss , energy and high electricity efficiency --- loss saving 70% compared with the traditional transformer no-Load electricity consumption;

2. Three column amorphous core,adopting the invention patenttechnology which has Ultra low working noise and solve thoroughly high working noise;

3. Low energy consumption and low loss characteristics of amorphous materials can save power consumption .reduce thepower generation, decrease relative S02 and C02 exhaustemission, reduce environmental pollution and greenhouse effect, it is maintenance free and zero pollution;

4. Low working temperature,the full load operating temperature less than 70℃,the insulation degradation slow so that the service life is long very much;

5. High overload capacity,high mechanical strength;

6. The amorphous core retain has the characteristics of low ironloss and low magnetizing current when passing high frequencyflux, so it will not cause core saturation and posses good harmonic resistance;

7. Fast capital recovery.
