Cable oil is a specialized insulating fluid used in oil-filled high-voltage power cables. Its primary role is to provide electrical insulation between the conductors and to dissipate heat generated during operation. The oil fills the spaces within the cable, preventing electrical discharge and ensuring efficient power transmission. It also acts as a coolant, maintaining the temperature of the cable within safe operating limits and thereby extending the cable’s lifespan.
