20KV dry type transformer and 20 (10) KV high voltage dual voltage dry type transformer

The construction of national urban power grid and restructuring of agricultural power grid make distribution network at 20kV. Because it needs some time for 10kV power supply is changed to 20kV in some regions, it is urgent to supply power with transformers, some users will order 10kV and 20kV dual voltage distribution transformers from transformer manufacturers. In the international market, quite a few of countries have several power supply systems due to historical reasons (10kV, 20kV and etc.). In view of the actual situation, we design and develop high-voltage dual voltage distribution transformer for 10kV and 20kV accordingly.

After 10kV and 20kV are transformed, the connection group and tapping voltage ratio are unchanged;

The ampere-turn arrangement of transformer's winding is reasonable, and the capacity withstanding short circuit is strong;

In two voltage operation status, there is no spare turn, and the load loss of transformer is low;

It is convenient for users, and conversion between two voltages only needs to change the external wiring of high voltage.

Note: we can produce 20kV/0.4kV SC(B) series dry-type transformers (i.e. it can be connected with single 20kV grid at the side of high voltage).
