Voltage regulating mode: no-load voltage regulating; Insulation class: F class; Tap range: ±5%、±2*2.5%
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.
