    摘要： An end fitting having a bore that forms a sleeve for the shank of an electrical insulator of composite structure. The bore has a substantially frustoconical wall that flares away from the bore opening towards the end wall of the bore and has an annular swelling directed towards the inside of the bore. This complex shape for the wall of the bore contributes to reinforcing the strength of the fixing between the end fitting and the shank by interference due to heat shrinking.

    摘要： A composite electrical insulator suitable for high tension open air use wherein the insulator has an interior structural rod of an electrically insulating material and an outer coating formed of a thermoplastic material and having a plurality of radially extending sheds formed integrally therewith, the outer coating terminating adjacent the ends of the interior rod, the coating having at least two radially extending abutting surfaces formed to abut against mating abutting surfaces formed on an end fitting. The insulator provides good mechanical properties while being light weight and meeting all electrical requirements.

    摘要： A metal fitting for a composite electrical insulator (1) including a plastic rod (2), e.g., an FRP rod. The metal fitting (4) includes a radially inwardly deformable sleeve portion having a bore (5) into which an end portion of the rod (1) can be inserted for fixedly securing the metal fitting (4) to the rod (1). The bore (5) in the metal fitting (4) has an inner surface which is formed with fine protrusions (7). These protrusions (7) provide a satisfactory resistivity to the tensile force applied to the insulator (1), to thereby effectively prevent withdrawal of the rod (2) from the metal fitting (4) when it is in use.

    摘要： A high voltage porcelain insulator has a plurality of sheds extending laterally thereof at spaced apart locations therealong. The creepage path length of the shedded insulator is extended by mounting polymeric insulating creepage extenders on the porcelain sheds. The creepage extenders do not extend completely around the periphery of the sheds but leave a gap. Preferably the gaps of adjacent creepage extenders along the insulator are not aligned.

    摘要： An improved synthetic resin insulator comprising a reinforced plastic rod and a holding metal fitting having a sleeve is disclosed. In the insulator, the reinforced plastic rod is firmly secured to the sleeve of the holding metal fitting by a divided die means including at least five pieces, wherein the rod is inserted into the sleeve and the outer surface of the rod is substantially uniformly compressed in the centripetal direction by the inner surface of the sleeve by pressure exerted by each of the five divided die means pieces, so that the outer circumference of the rod is uniformly compressed at an optional cross-section thereof. The insulator is free from cracks and whitening in the rod and has an improved durable life.

    摘要： A tapered end fitting for a glass fiber rod applies a substantially uniform stress to the portion of the rod falling within the end fitting, and thus can withstand tensile loadings up to the tensile strength of the rod itself. A uniform stress distribution is achieved by designing the end fitting so that it subjects to the rod to a uniform volume strain. This, in turn, is achieved either by properly tapering the inner surface of the end fitting outer jacket, or by properly choosing the characteristics of the collect which fills the space between the rod and the outer jacket of the end fitting.
