What is a cable oil purification unit and how is it utilized?

A cable oil purification unit is a specialized piece of equipment designed to remove contaminants from cable oil, restoring its insulating and cooling properties. It is utilized by:

Connecting to the Cable System: The unit is linked to the cable oil circuit via inlet and outlet hoses.
Processing the Oil: Oil is circulated through the unit, where it undergoes heating, filtration, degassing, and dehydration.
Monitoring: Operators use control panels to monitor system parameters and adjust as necessary.
Mobile or Stationary Use: Units can be portable for on-site purification or installed permanently at substations or maintenance facilities.
Routine Maintenance: Regular use of the unit as part of preventive maintenance schedules ensures ongoing oil quality and cable performance.
Utilizing a purification unit helps prevent cable failures and extends the operational life of both the oil and the cables.
