110 kV, on-load tap changer
Power transformer 110 kV with OLTC
110 kV oil-immersed transformer with an on-load tap changer: it regulates voltage under load without disconnection and keeps it stable when the network fluctuates. Suited to networks with frequent voltage fluctuations and sharp load changes.
