What are the specific characteristics of high-voltage cable oil?

High-voltage cable oil possesses several key characteristics:

High Dielectric Strength: To effectively insulate and prevent electrical discharges.
Thermal Stability: Ability to withstand temperature variations without degrading.
Low Viscosity: Ensures proper flow and heat dissipation within the cable.
Chemical Stability: Resistance to oxidation and chemical reactions over time.
Moisture Resistance: Low affinity for water to prevent reduction in insulating properties.
These characteristics enable the oil to perform reliably under the demanding conditions of high-voltage power transmission.
