Features of Products:

When a series of dry-type transformers is connected to a line voltage of 20kV or 10kV, the connection state between two windings of each phase high-voltage coil is controlled by a conversion device, and the purpose of voltage conversion is achieved in series or parallel, while the output voltage is constant. Thereby realizing a transformer product can be connected to the 10kv, 20kv class two voltage systems during the non-synchronous period. It is a transitional product when the network power 10kv will be upgraded to 20kv. It can reduce the repetitive investment but convenient and quick conversion and also has stable product performance.
