Abstract

An optical fiber composite insulator including a hollow insulator body having an axial through-hole and at least one optical fiber extended through the through-hole and hermetically sealed to the inner surface of the through-hole by a sealing material. A relationship between a condition of the inner surface of the through-hole and the sealing material, a relationship between the inner diameters of the through-hole and the outer diameter of the hollow insulator body or a coating material on the optical fiber are selected to provide high insulating property, mechanical strength and airtight property of the optical fiber composite insulator.
