摘要： Method and apparatus for manufacturing a composite insulator which includes an FRP core rod covered by a sheath and provided with a plurality of sheds which are made of an electrically insulating polymeric material. The sheds are set on a support member arranged on a downstream side of an extruder. The extruder is fed with a core rod and extrudes a polymeric material to form a sheath on the core rod. The core rod with the sheath is moved toward the downstream side through an opening in the support member. The sheds are sequentially moved along the support member toward the downstream side and transferred onto predetermined locations on the sheath that have passed through the opening and have reached the downstream side. An assembly is thus formed which includes the core rod, sheath formed on the core rod, and sheds transferred onto the sheath. The assembly is then heated to vulcanize the sheath and adhere it to the core rod and the sheds.

摘要： A composite insulator is provided. At least one metal end fitting is provided having a sleeve portion which defines a bore with a first diameter, d1. An insulator subassembly is then formed. The insulator subassembly includes a rod of electrically insulating plastic material and an insulator sheath covering at least a portion of the outer surface of the rod. An end portion of the sheath has a deformable circumferential ridge formed on the outer surface thereof. This circumferential ridge has a second diameter, d2, which is greater than the first diameter, d1. The insulator subassembly is then inserted into the bore of the metal end fitting with a spacer member interposed between the metal end fitting and at least the circumferential ridge. The spacer member serves to deform the ridge to define a temporary vent for allowing air within the bore to escape. The spacer member is then removed thereby allowing the resilient ridge to return to its original size and shape to form a tight seal between the metal end fitting and the insulator subassembly. The resultant composite insulator has a construction which includes an insulator subassembly including a rod and a sheath covering at least a portion of the outer surface of the rod. The sheath has an end portion and at least one deformable circumferential ridge formed on an outer surface thereof. The composite insulator also includes a metal end fitting having a sleeve portion that surrounds the end portion of the sheath. An end region of the metal end fitting that overlaps the ridge is free from deformation. As a result, it is no longer necessary to crimp the metal end fitting to form a good seal, although the crimping step could be performed if additional tigntness is desired.

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.
