What can the CTBU machine do for you?
The two stage trailer mounted transformer oil purification machine is required to provide the following functions:
A nominal rate of at least 6000Liter or adjustable.
Purification of oil transformers out of service.
Oil Filtration: removal of solid particles suspended in the oil.
Vacuum Dehydration: extraction of water dissolved in the oil.
Gas Venting: extraction of gas are dissolved in oil.
Reference standard:
The purpose of the transformer oil purifying operation is to bring the mineral insulating oils into conformity with the standards listed below (including the test procedures):
IEC 60296: Fluids for electrotechnical applications
IEC 60422: Mineral insulating oils in electrical equipment - Lines. Guidelines for maintenance and monitoring
IEC 60156: Determination of breakdown voltage at industrial frequency,
NFC 15100: Low-voltage electrical installations,
ISO 4406: Hydraulic fluid power - Fluids - Method for coding the level of contamination by solid particles
Features:
The transformer oil filtration machine can be able for use with none energized power transformer and will have:
1. Oil flow rate 5000 liter/hour or more.
2. The heating speed can be more than one step.
3. Vacuum level can be between one to four absolute m bars.
4. The minimum filtration range can be not less than 2 absolute μ.
5. Dissolved moisture on the final content can be <7ppm.
6. The dissolved gas on the final content can be <0.2% by volume.
7. Can reach with the treat oil a dielectric strength not less than 70kv.
