Cargill Envirotemp FR3 dielectric fluid identified as technology enabler in new IEEE high temperature insulation standard

January 31, 2013 |

In Minnesota, Cargill reports that demonstrated enhanced thermal capabilities of its Envirotemp FR3 renewable dielectric fluid, which is made from vegetable oil, have been published within a new design standard by the Institute of Electrical and Electronics Engineers.

Industry-standard temperature limits for electrical transformers are traditionally capped at 110-degrees Celsius. IEEE’s new standard (C57.154) sets the upper operating temperature limit of transformers designed with natural esters (FR3 fluid) at 130-degrees Celsius without adversely impacting transformer life.
