Transformer Oil Filter Specifications and Dimensions

The following are typical specifications and size parameters of transformer oil filters, covering key data such as flow rate, accuracy, and external dimensions for your reference:

Core Specifications

| Parameter Item | Common Range | Description |

|------------------|--------------------------|---------------------------------------|

| Flow Rate | 1000~12000 L/h | ｓｅｌｅｃｔ according to transformer oil volume (recommended processing volume is 2-3 times the total tank capacity/hour) |

| Filtration Accuracy | 1~5 μm (NAS Level 6 or below) | Transformer oil must reach ≤5μm (GB/T 7595 standard) |

| Working Pressure | 0.3~0.6 MPa | Overpressure may damage the filter element |

| Vacuum Degree | -0.08~-0.098 MPa (if equipped) | Parameters for vacuum dehydration models |

| Heating Power | 15~75 kW (optional) | For low temperature environment (heating is required when oil temperature is less than 40℃) |

| Power supply | 380V/50Hz (three-phase) | Industrial voltage is required for large flow models |

II. External dimensions reference (different flow models)

| Flow (L/h) | Length (mm) | Width (mm) | Height (mm) | Weight (kg) | Movement |

|----------------|-------------|-------------|-------------|---------------|--------------------|

| 1000~2000 | 1200~1500 | 800~1000 | 1400~1600 | 300~500 | With universal wheels |

| 3000~6000 | 1800~2200 | 1000~1200 | 1700~2000 | 800~1200 | Forklift slot/trailer hook |

| 8000~12000 | 2500~3000 | 1500~1800 | 2200~2500 | 2000~3500 | Fixed installation required |

Interface size (standard configuration)

- Oil inlet/outlet: DN25~DN80 (flange or quick-connect interface, matching transformer valve size)

- Drain port: DN15 (vacuum model used to discharge separation water)

- Power cord: 3-core/5-core cable (length is usually 3~5m, customizable)

Selection considerations

1. Matching transformer capacity:

- Small transformer (≤1000kVA): ｓｅｌｅｃｔ 1000~3000 L/h model.

- Medium transformer (1000~5000kVA): ｓｅｌｅｃｔ 3000~8000 L/h model.

- Large transformer (≥5000kVA): ≥10000 L/h model needs to be customized.

2. Space restrictions:

- Check the equipment size with the transformer room door width and channel height (it is recommended to reserve ≥200mm operating space).

Operation suggestions

- Pre-installation inspection: confirm the ground load-bearing capacity (≥500kg/m²), power supply distance (avoid voltage ｄｒｏｐ of long cables).

- Maintenance space: ≥800mm width should be reserved on the filter replacement side.
