摘要

"Colloidal fluid, processes for preparation of the same and for insulation and cooling of an electromagnetic device which produces a magnetic field and external heat and electromagnetic device.Colloidal fluids have properties improved isolation and / or refrigeration.The embodiments of the invention relates to colloidal fluids that comprise a liquid carrier and a dispersed phase of non - metallic particles.Where the colloidal fluid has a magnetization of saturation of less than 50 Gauss.The compositions may be employed to isolate and / or cooling magnetic devices, including devices of high power, such as power transformers.
