 250kVA dry type transformer

Features of 250kVA dry type transformer:

No oil leakage, small size, light weight;

2. The wiring is simple, intuitive and easy to use;

3. Good insulation reliability and beautiful appearance;

4. Any specification can be customized;

5. Cascade connection, small volume, convenient for field test.

[product introduction]

250kVA dry-type transformer outputs AC and DC high voltage, providing high voltage for various high-voltage tests. 250kVA dry-type transformer is used for field test of insulation performance of various electrical equipment.

250kVA dry-type transformer is the introduction of foreign advanced technology, the use of advanced production equipment, the use of coil epoxy vacuum casting molding, and CD type iron core of the new technology, new materials, compared with the same capacity, the same voltage oil immersed test transformer, has the advantages of light weight, small volume, beautiful appearance, stable performance, easy to use and carry, no oil leakage and so on. The magnetic flux leakage is weakened and the insulation strength and moisture resistance are improved. It is especially suitable for testing the insulation performance, DC withstand voltage and leakage current of various electrical equipment in the field of power system and power users. It can replace the heavy oil immersed transformer at present.
