- Applicable standards
Relevant manufacturing and testing standards are in accordance with CNS 13390 C4468 or IEC 60076-11 specifications unless otherwise specified by the customer.
- Applicable conditions
a.Load: continuous rated load.
b.Location of use: indoor type below 1000 meters above sea level.
c.One week temperature: maximum 40 ° C.
d.Insulation class: Class F
- Transformer characteristics
a.Type: self-cooling, indoor type, resin type dry winding.
b.Rated voltage and wiring: according to customer requirements or primary side: △ wiring, secondary side: △ or Y wiring.
c.The transformer runs continuously under the ambient temperature of 40 ℃, the rated capacity and the rated frequency. The winding temperature rise measured by the resistance method must not be higher than 100 ℃.
d.The above performance is a reference value.All performances should be marked based on the final approval information or test report.
e.For other specifications transformers, relevant technical data will be provided separately according to customer requirements.
- core:
a.Manufactured from cold rolled silicon steel sheet with high directivity, high permeability and low loss.
b.The iron core is fixed with high-strength iron parts and can withstand the vibration that may occur during transportation, installation and operation.
c.The surface of the iron core is coated with resin paint or anti-rust paint to prevent the silicon steel plate from absorbing moisture and oxidation.
