In what applications is cable oil purification most critical?

Critical applications include:

High-Voltage Transmission Lines: Where failure can lead to widespread power outages.
Underground and Submarine Cables: Difficult to access for repairs, making preventive maintenance essential.
Aging Infrastructure: Older systems may be more prone to oil degradation and contamination.
Harsh Environmental Conditions: Areas with high moisture, pollution, or temperature extremes.
Industrial Facilities: Where reliable power supply is crucial for continuous operations.
Renewable Energy Integration: Transmission of power from remote renewable sources requires reliable cables.
Critical Infrastructure: Powering hospitals, data centers, and other vital services.
In these applications, cable oil purification is vital to prevent failures and ensure uninterrupted power delivery.
