Estimating the term…
An improved insulating material is provided. The insulating material is a mixture of an insulating fluid and solid insulative bodies. The insulating material exhibits desirable insulating, conformal coating, surface adhesion, and low-viscosity characteristics. For example, when the insulating material is used to fill the cavity of a hollow insulator, the insulating material prevents any moisture that enters the insulator from adhering to the walls that define the cavity; thus maintaining the insulating qualities of the insulator. In the event that some of the fluid is lost through leakage, the insulating material also aids in preserving the insulating qualities of the insulator.
An insulating material consisting of 10% to 80% by volume of an insulating fluid and 20% to 90% by volume of solid insulative bodies, the relative volumes and densities of said insulating fluid and said solid bodies, and the shape of said solid bodies being determined to provide a relatively free-flowing mixture, the densities of said insulating fluid and said solid insulative bodies being generally equal, the apparent viscosity of the insulating material to an object moving therein being less than 20 times the viscosity of said insulating fluid.
An insulating material consisting of 10% to 80% by volume of an insulating fluid and 20% to 90% by volume of solid insulative bodies, the density of each of said insulating fluid and said solid insulative bodies being generally equal.
