 20kV - 250kVA Cast Resin Dry Type Transformer , Three Phases , Two Winding , Power Distribution​
 

    
Advantages:

  1. A good ability of withstand short-circuit.
  2. The dry-type transformers are casted with epoxy resin, which are made of high quality materials by means of a strict process with advanced production and testing devices.
  3. The product features high reliability and long service life. Besides, it can be equipped with different protection casings or without casing in accordance with different operation environment.
  4. Excellent after-sales service
  5. Punctual delivery
  6. This product may convert between 10KV and 20KV voltages, and the user doesn't need to make second input, thus saving the investment.
  7. The product applies to the areas where the load density is high and the power demand grows rapidly

 
Product Uses:
 
With excellent performers, it can overcome those harsh operation conditions: high altitude, high humidity, high temperature and large temperature difference.
In daily life, it is exactly suitable for the places like government offices and bureau residential area and other areas that strictly demand of special require for fire proof.
Rising the challenge of large load fluctuation or long time overload places, it can be widely used in some places, for instance, urban rail, metallurgical industries, power plants, shopping mall and so on.
 
 
Characteristics:
 
It has effect of cooling capacity and high performance such as moisture proof and light shock resistance.
It meets the needs of environmental adaptability and lighting shocks, strong resistance to thermal shock, anti-cracking and recycling.
 
Safety:
It adopts NOMEX insulation systems in the main insulation, inflaming retarding, explosion proof and so on.
Vacuum pressure impregnation curing process, high mechanical strength, withstand short-circuit, safe and reliable.
 

 
Cast Resin Dry Type Transformer, Low Noise, Low Loss and Low Partial Discharge.

Accessories and other considerations
Aside from the windings, other parts of the transformer, such as bushings, cable-end
connections, tap-changing devices, tap changer, temperature measurement devices, surge
arresters and leads may restrict the operation at 1,5 times the rated current.

Transformers in an enclosure


Consumption of life time due to overload is higher when the transformer is in an enclosure.
When transformers are used indoors, a correction should be made to the rated hot-spot
temperature rise to account for the enclosure.


 Outdoor ambient conditions


In many parts of the world, direct sunshine may increase the transformer temperature
drastically, which should be taken into account when loading beyond rated current is
considered.Wind may improve the cooling of the transformer, but its unpredictable nature makes it
impractical to take into account.
