ABSTRACT:
In a mineral insulated electric cable the powdered insulating material is impregnated with a quantity of a hydrophobic material, for example a silicone, which has been introduced into the powder in liquid form. The added hydrophobic material serves as a barrier against the ingress of moisture, and liquid dimethylpolysiloxane has been found particularly effective, the pressure of even a small quantity of this preventing any significant degree of moisture penetration into the cable.
