In a method of producing a composite insulator having a core member, end fitting members fixed to both end portions of the core member, and an overcoat member including a sheath portion formed on an outer surface of the core member and shed members, the overcoat member and the end fitting member are connected by curing. Moreover, a clamping operation is performed or a packing member is used for preventing a flow of an overcoat forming material into a seal portion. In this manner, it is possible to improve a seal performance of a connection boundary between the end fitting member and the overcoat member.

A forming die including of a holder having an upper portion and a lower portion, each portion having a main substrate extending in a first longitudinal direction. A fixing substrate is located on one end of the main substrate and a movable substrate is located on an opposite end of the main substrate and is movable along the main substrate in the first longitudinal direction. A plurality of die forming segments are situated between the movable substrate and the fixing substrate. Tie rods extend along the main substrate outside the periphery of the plurality of die forming segments, and connect the movable substrate and the fixing substrate to one another.

A disclosed method of repairing a shed portion of a composite insulator having a core portion, a sheath portion arranged on an outer surface of the core portion, and a plurality of shed portions projected from the sheath portion, includes the steps of, (1) cutting out the shed portion having defects from the sheath portion while leaving the sheath portion, and connecting a new shed portion having the same shape as that of the cut out shed portion to the sheath portion at the cut out portion, or (2) cutting out partly the shed portion having defects, and connecting a repairing member to the cut out portion. Therefore, it is possible to perform the shed portion repairing operation without wasting the normal shed portions.
摘要:
A method of producing a composite insulator having a sheath and shed portions molded around a core rod, grasping metal fittings engagingly fitted and fixed at both end portions of the core rod, the sheath covering the core rod between the grasping metal fittings on the whole circumference of the core rod, and a plurality of shed portions extruding radially outwardly from the sheath at plural positions spaced from each other in the longitudinal direction of the core rod, by filling an insulative high molecular material and subsequent vulcanization thereof in the cavity of molding die portions. The method includes positioning and retaining the core rod at a desired position in the cavity of the molding die portions by means of retaining rings engagingly fitted on the grasping metal fittings and allowing an excess portion of the insulative high molecular material filled in the cavity to flow out to the exterior of the cavity between the grasping metal fittings and the retaining rings.
摘要:
A composite insulator includes a FRP core rod and a sheath which is formed by integrally molding an insulating polymeric material to cover the core rod over substantially the entire length thereof. The sheath is composed of a plurality of molded portions which are aligned with each other in the axial direction of the core rod. Adjacent molded portions of the sheath are arranged relative to each other so that a gap is left between the opposite ends of the molded portions. The gap is filled by a joint insulating material which is integrally united to the polymeric material of the adjacent molded portions.
