CONSTITUTION: This is an insulated operation rod used for high-voltage equipment, and has the following constitution. An insulated rod is made of fiber-- reinforced plastic rod in the shape of a hollow cylinder. Liquefied rubber molding materials 11 cover the inside periphery and the outside periphery of the insulated rod 1A. Connecting metal fittings 9 and 10 in the shape of relieving electric fields are attached to both ends of the insulated rod 1A, and screw couplings 1a and 9a and 1b and 10b for coupling the insulated rod 1A with the metal fittings 9 and 10 are provided.

摘要： PURPOSE:To avoid cracking and a partial discharge by a method wherein a carbon fiber layer is provided in the boundary between an insulating spacer and a fixing part. CONSTITUTION:A meshy carbon fiber layer 6 is provided in the boundary between an insulating spacer 1 and a metal flange 3. The carbon fiber layer 6 absorbs the interfacial tension between the insulating spacer 1 and the metal flange 3 which is generated when the insulating spacer 1 is cured and contracted and when heat cycles are repeatedly applied to avoid cracking in the boundary. Further, even if the boundary between the insulating spacer 1 and the metal flange 3 is peeled off, as the carbon fiber layer 6 and the metal flange 3 have the same potential, a partial discharge can be avoided.

摘要： PURPOSE:To correspond to an arbitrary wire cable and to simplify the mounting to the wire cable by integrally molding a rubber ring having an arbitrary hollow hole formed from outdoor liquid rubber by an outdoor resin. CONSTITUTION:A rubber ring 13 having an arbitrary hollow hole 12 formed from outdoor liquid rubber is integrally molded along with an outdoor resin 1a. Since the mounting part to a wire cable is the ring 13 formed from the outdoor liquid rubber, one having an arbitrary diameter is obtained only be setting the ring 13 having an arbitrary diameter at the time of molding. Therefore, the mounting to the cable can be simply performed in a gapless state. Further, because of the same rubber material as the cable, no gap is generated even when there is temp. difference due to a seasonal change. As the outdoor liquid rubber, a main agent prepared by compounding an ultraviolet absorber or a light stabilizer and an oxidation inhibitor with a hydrogenated polyhydroxybutadiene polymer and a polyfunctional isocyanate compound having two or more isocyanate groups in its molecule are pref.
