Note: 1. Our factory's test transformer can achieve an AC voltage of 300kV and a capacity of 300kVA per unit;
2. If required by the user, the test transformer produced by our factory can extract 200V series tap and cascade two or three units into AC high voltages of 100kV, 150kV, 200kV, and 300kV. According to the user's needs, a medium voltage tap of 5-15kV can also be extracted from the high-voltage winding for AC withstand voltage testing of the high-voltage motor;
3. The 'DC High Voltage Output' column in the table represents the DC high voltage output value of the AC/DC dual-purpose test transformer;
4. Our factory can also customize various special specifications of test transformers according to user requirements.
