Answer / santosh mahato

lubricating oil is used in order to reduce friction from
moving parts, to make somthing run smoothly without any
problem.
But,insulating oil is used to insulate parts at different
electrical potential i.e., to protect or isolate some
meterials from the passage of electricity.

Regarding the viscosity of the insulating fluids it is
highly desirable that they have a low viscosity (as long
they keep inflamability at a reasonable level) as this
helps the removal of heat out of the transformer.
Hope this is of help.

LUBRI CATING OIL IS USED FOR PROVIDING SMOOTHNESS AND
REDUCE FRICTION AND INSULATING OIL IS USED FOR PROVIDING TO
ELIMINATE THE HEAT AND IMPROVE THE DIELECTRIC STRENGTH OF
EQUIPMENT.

Answer / hemakumar

Lubricating oil is normally used in mechanical moving parts.

But in insulating oil is a mineral oil and having non
current carring capacity depends upon a tested voltage
level. Normally insulating oil will used in transformer
cooling purpose (After tested the "BDV" Break Down Voltage).

Answer / lenovouser

too much different
u measure short ckt test then u find more breaking capacity in insulation oil 40 kv/mm to 50 kv/mm

and other is viscosity is more in lubrication oil
