We regularly perform our spirit of ''Innovation bringing progress, Highly-quality making certain subsistence, Administration marketing benefit, Credit score attracting customers for Ais Gis Substation, Air Insulated Panel, 24kv Metal Clad Switchgear, We glance forward to receiving your enquires shortly and hope to have the opportunity to function along with you inside the future. Welcome to acquire a glimpse at our organization.
Factory directly Unit Substation Transformer - SZ11 SZ13 intelligent adjusted Oil immersed distribution outdoor transformer – Nady Detail:

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;
