Description

The 22KV Dry Transformer boasts the following features:

  • The encapsulation layer resin thickness has been reduced, enhancing the heat dissipation capacity of the coil.
  • The coil has been reinforced with glass fibre reinforced mesh plates, improving its mechanical properties and resilience to sudden short circuits.
  • The coil has been manufactured using a vacuum casting process, reducing the coil's susceptibility to partial discharge. The improved coil electrical strength, high explosion-proof overload capacity, good stability against hot and cold shocks, and low noise are key benefits.
  • The temperature control and wind cooling device, three-phase temperature display on the same screen, automatic start and stop of the wind machine, fault alarm, over-temperature alarm, over-temperature trip and black coil functions, and pass RS485 serial communication are also noteworthy features.
