摘要： There is disclosed a method of installing spiral hangers for hanging a cable on a messenger wire installed between a pair of electric utility poles. One end of a spiral hanger is first movably attached to the messenger wire in the vicinity of one of the electric utility poles. The spiral hanger has an inner diameter greater than the sum of the outer diameter of the messenger wire and the outer diameter of the cable. Subsequently, the spiral hanger is transported toward the other of the electric utility poles, and the other end of the spiral hanger is joined to one end of a succeeding spiral hanger through use of a joint sleeve. Above-described operations are repeated, and the spiral hangers are fixed to the messenger wire through use of fixing devices when the first spiral hanger arrives at the other of the electric utility poles. Subsequently, a cable is passed through the spiral hangers through use of a pull-rope threading implement, whereby the cable is installed by work performed only in the vicinity of the electric utility poles. Special implements are used in order to facilitate the installation of the spiral hangers.

摘要： A PC strand is coated with rust inhibitive material of thermoplastic resin so as to wholly close spaces left around a core and peripheral wires twisted around the core, thus preventing the core and wires from rusting. The strand coated with the rust inhibitive material can be produced without being untwisted by use of an extruding machine having an auxiliary pressure head connected to a cross head.

摘要： In a method of hanging a cable by using spiral hangers on a messenger wire installed between a pair of electric utility poles, one end of a spiral hanger and a leading end of a pull rope are connected to a leading pulley in the vicinity of one of the electric utility poles. A spiral hanger having an inner diameter greater than the sum of the outer diameter of the messenger wire and the outer diameter of the cable is transported toward the other of the electric utility poles while surrounding the messenger wire and the pull rope. The other end of the spiral hanger is connected to one end of a succeeding spiral hanger by using a joint sleeve, and this operation is repeated. When the leading pulley arrives at the other of the electric utility poles, the spiral hangers are fixed to the messenger wire using fixing devices. After that, the pull rope is pulled so as to pull the cable connected to the tail end of the pull rope through the spiral hangers. With this operation, the cable can be installed by work performed only in the vicinity of the electric utility poles.

摘要： A PC strand is formed by twisting peripheral wires made of deformed PC steel wires around a core, and allowing rust inhibitive material of thermoplastic resin to permeate into voids defined among the core and peripheral wires by use of an extruder. Since at least one of the core and peripheral wires is made of a deformed PC steel wire having an uneven outer surface, the thermoplastic resin can smoothly permeate deep into the inside of the PC strand.
摘要翻译：通过将由变形的PC钢丝制成的外围线缠绕在芯上，并且使热塑性树脂的防锈材料通过挤出机渗透到芯和外围丝之间的空隙中而形成PC绞合线。由于芯线和外围线中的至少一个由具有不均匀外表面的变形PC钢丝制成，所以热塑性树脂可以平滑地渗透到PC股的内部。
