SZ11 SZ13 intelligent adjusted Oil immersed distribution outdoor transformer

Short Description:

  • This product conforms to the national standard GB1094.1-2013(IEC 60076) power transformer and GB / T6451-2015 three phase oil immersed power transformer technical parameters and requirements. The three-phase oil -immersed distribution transformer applies new type insulating structure. The iron core is made of high-quality cold-rolled silicon-steel plate. High-voltage winding group is made up of high-quality oxygen-free copper lines and it adopts multi-layer drum type structure. All fasteners have been processed with special treatment to prevent them from loosening.
  • As high-tech product that promoted by the country, the product has many advantages such as high efficiency, low loss. Its social benefits are remarkable that it will save much of electricity consumption and operating cost.

Product Detail

Product Tags

Compared with the original SZ11, the average of SZ13no-load loss reduced by 20% or more, the no-load current is reduced by 25% or more, operating costs dropped by an average of more than 15%

  Relative to the conventional S11 type/S13 series three-phase double-winding and excitation surge of transformer power after manual voltage regulator, SZ11 SZ13 type series transformer can realize the load, through the controller on the ground remote power transformer to adjust the voltage, which can realize free power voltage regulator, reducing frequency of climbing and risk, greatly convenient for power operation personnel on site.

Main Functions And Features

1. The low-voltage winding is of cylindrical or spiral structure, with high mechanical strength and good short-circuit resistance.

2. The corrugated oil tank is adopted to replace the oil conservator. The oil tank cover and the oil tank are all welded along the edge or fastened with bolts, thus prolonging the service life of the transformer oil.

3. After oil removal, embroidery removal and phosphating treatment, the product is sprayed with three times of primer and one time of finish paint inside and outside. The product is salt fog proof, damp heat proof and fungus proof, which can meet the special requirements of metallurgy, petrochemical system and wet and polluted areas. It is beautiful and reliable.

4. The transformer oil tank is fully sealed, and equipped with pressure reducing valve, signal thermometer, gas relay, etc according to the standard requirements to ensure the safe operation of the transformer.

5. This series of products are beautiful in appearance, small in size, and can reduce the installation area. It is an ideal maintenance-free distribution product.

6.We employ spiral coil with longitudinal oil path to make a better interior cooling effect;
