Mobile oil units СММ-U (Mobile oil units – МCU) are designed for insulating oils purification of
mechanical contaminants and water as well as for their acidity reduction. Viscosity of aforementioned oils
should be less 70 cSt under the temperature of 50°С. Present fabrication can be used while assembling,
maintaining and exploiting oil-filled high-voltage equipment (such as power transformers, high-voltage
switches, etc.) of less 1150 kV voltage.
