| 摘要 |
Colloidal fluids having improved insulating and/or cooling properties. Embodiments of the invention involve colloidal fluids which comprise a carrier liquid and a dispersed phase of non-metallic particles, wherein the colloidal fluid has a saturation magnetization of less than about 50 Gauss. The compositions may be employed to insulate and/or cool electromagnetic devices, including high power devices, such as power transformers.
