220kv Grade Three-Phase Three-Windings Oil Immersed ONAN/ONAF Power Transformer
220kv power transformer is used in 230kv or 252kv power system
220kv oil filled power transformer:
Feature:
220kv on-load tap changer power transformer is made of high-quality silicon-steel sheets,and laminated by steps,it is advantageous in low loss,low noise ,low voltage partial discharge and high anti short circuit capacity.the dynamical and thermal stability of this transformer ,of which the coils are winded by high-quality oxygen-free copper wire as well as used pre-compressing brackets processes and interior and exterior structure.the transformer tank used wave form shell.has very nice appearance ,the core is with D shape yoke and 45 angle seaming,the core and oil box are well fixed .
The technical parameter of the power transformer with OLTC high voltage transformer as follows:
| Rated power(kVA) | High Voltage(kV) | H.V Tap range | Low Voltage(kV) | Connection Symbol | Short-Circuit Impedance(%) | No-load Loss(kW) | On-Load Loss(kW) | No-load Current(%) | ||||
