摘要： A composite insulator includes a hollow and tapered core portion composed of fiber-reinforced plastics, and a sheath and sheds composed of an insulating polymeric material integrally molded on the outer surface of the core portion. The core portions of composite insulators for a plurality of voltage classes are formed by using a mandrel assembly in which a plurality of mandrel members are combined. The so-prepared core portion is placed within a mold unit in accordance with the voltage class of the composite insulator to be manufactured, and the insulating polymeric material is poured into the mold cavity to integrally mold the sheath and the sheds.

摘要： A composite insulator having a core member and a housing member integrally arranged around the core member, the housing member being constructed by a trunk portion and a shed portion, has a creepable distance extending means arranged on a lower plane of the shed portion. Moreover, a segment used for producing the composite insulator has a pair of segment molds detachably connected at a partition plane having a through-hole at its center portion through which the core member is arranged, an upper plane forming portion arranged at its one end surface for defining an upper plane of the shed portion, and a lower plane forming portion arranged at its other end surface for defining a lower plane of the shed portion; and a partition for forming the creepage distance extending means arranged at the lower plane forming portion. Further, the composite insulator is produced by arranging the core member in a through-hole of a mold constructed by integrating a plurality of segments, supplying an elastic polymer material into a space between the mold and the core member, curing the elastic polymer material and separating the mold at the partition plane.
