Our 1500Kva dry-type transformers need to be designed before production, and when confirming the design of the transformer, we need to pay attention to the two aspects of the winding and insulation.
First of all, confirm that the drawings are consistent with the production of products, to confirm its capacity is correct and then look at the line gauge, find out the line gauge to confirm the number of turns. Secondly, to confirm what kind of wiring, high-voltage drawings to look at its tap out, count the number of turns out of the head, low-voltage look at what kind of winding, the length of the head, the position of the transposition, the winding of the inner and outer diameters, amplitude to the size and so on.
Secondly, according to the coil inside the warp calculate the length and width of the paper tube cardboard, and then from the drawing number to find out the length of the end of the insulation drawings, including oil channel pads and corrugated oil channel thickness, in turn, to find out the end of the circle and the upper and lower iron yoke insulation.

1500 kva dry type transformers
dry type power transformer feature
- The capacity of the dry-type transformers is quite large. Dry power transformers for distribution systems are built with capacities between 50 and 2,500KVA, dry power transformers with capacities between 10,000 and 20,000KVA / 35KV and in the public future. productivity will be even greater.
- Dry transformers are widely used in power distribution systems, self-use systems of power plants, excitation systems, locomotive power supply systems running on railways, subways, homes nuclear power machine. dry-type transformers are also popularly used in hotels, stadiums, petrochemical plants, airports, and drilling rigs and especially where there are strict fire protection requirements.
- Dry-type transformers are capable of withstanding an overload. For places where the load is not uniform during the day, such as lighting electricity, cultural areas, air-conditioners, etc., the capacity of the dry-type transformers is smaller than the load to take advantage of the overload capacity of the them. The main service time of a transformers will be over or under overload. Using dry-type transformers it is possible to reduce their spare capacity or reduce the number of spare dry-type transformers.
