CMM-1CO Cable Oil Degassing Unit

The СММ-1СО is designed to remove solid particles, gas and moisture from cable oil1The cable oil is used to impregnate the paper insulation of cables and to fill the cables., to store portions of prepared cable oil and to add oil to OF cable 2An electrical cable is an assembly of one or more wires running side by side or bundled, which is used to carry electric current. lines with voltage up to 500 kV. The unit can also be used for evacuation of transformer3A transformer is a static electrical device that transfers electrical energy between two or more circuits. and other equipment.

The unit can process cable oil with the following initial quality:

  • moisture content below 100 ppm;
  • ISO4The International Organization for Standardization is an international standard-setting body composed of representatives from various national standards organizations. 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 vacuum5Vacuum is space devoid of matter.
