Transformer fluids are expected to act as an electrically insulating medium and heat transfer agent. It is thus desirable for the fluid to have a higher thermal conductivity. The thermal conductivity and more general heat transport properties of the material are considered important performance criteria in the selection of the transformer fluid. A quick and easy way of measuring this critical performance attribute of the product is offered with the Trident Thermal Conductivity Platform.
Testing results are presented in the table below and support the manufacturer’s claims of a higher thermal conductivity property for the material relative to other competitive transformer fluids. It is important to note that the heat transfer or more specifically, thermal conductivity, is only one of many performance properties for a transformer fluid.
