CMM-1CO CABLE OIL DEGASSING UNIT
CMM-1CO CABLE OIL DEGASSING UNIT
The СММ-1СО is designed to remove solid particles, gas and moisture from cable oil1, to store portions of prepared cable oil and to add oil to OF cable 2 lines with voltage up to 500 kV. The unit can also be used for evacuation of transformer3 and other equipment.
The unit can process cable oil with the following initial quality:
- moisture content below 100 ppm;
- ISO4 4406 purity class -/19/16 or better.
All components of the unit, except for prepared oil storage tanks, are installed in a container. Container front and sides are equipped with access doors for servicing the unit.
The СММ-1СО consists of a vacuum5 chamber, an input pump, a heater, an output pump, coarse and fine filters6, a control cabinet, a vacuum pump7 and a backing pump, as well as oil storage tanks.

Note – *Initial oil quality:
- Gas content below 10.5 % vol;
- moisture content below 0.01 % (100 ppm);
- temperature above 0 ºС.
- One unit for all cable oil tasks: dehydration and degassing of oil, evacuation of cable lines, and filling of makeup tanks.
- Improved reliability of oil-filled cable line operation.
- Easy operation and servicing;
- The unit can be manufactured in fixed-type (containerized, skid-mounted, tent-protected) or mobile (castor wheels, trailer) designs.
