Transformer Insulating oil’s primary functions are to provide insulation and cooling of a transformer. It can be thought of as the life-blood of the transformer, it must therefore have high dielectric strength, thermal conductivity, and low moisture content amongst other properties.

Dependant on type and rating of the transformer the oil may be circulated through external radiators, through which the oil circulates by either natural convection or is pumped. These radiators may have additional cooling fans to increase their heat transfer capability.

Before filling a transformer, it is beneficial to vacuum the transformer to ensure it is completely free of moisture, then filling the unit via a processing unit to ensure the oil is of the highest quality, giving the transformer the best start to its working life.

In certain sensitive locations traditional mineral oil based insulating oil may be replaced with a synthetic insulating fluid, Midel 7131 being a common alternative.
