摘要： PURPOSE: To secure the neat appearances neat and improve the workability in erection by a method wherein the outer diameter of a cable is made uniform by making the thickness of corrosion preventive sheathings covering strands different from one another when the strands for bearing mechanical strength for suspension are different from one another in the outer diameter. CONSTITUTION: The thickness for each of the corrosion preventive sheathings 6A-6C is determined in accordance with the maximum outer diameter of a strand 4a constructed of a plurality of wires 4, and the sheathing is made by extruding resin material to surround the strand 4a. The resin material to be used in extrusion of the sheathing must be of polyethylene or fluorocarbon resin, and the sheathing must be made in the outer diameter the same as a cable made by covering the strand 4a with the corrosion preventive sheathings 6A-6C. Parting agent 7, selected out of those higher in melting point than the resin material forming the corrosion preventive sheathings, is applied to parts between the corrosion preventive sheathings 6A and 6B, and 6B and 6C for preventing heat sealing from occurring to each of the sheathings. Thereby, the outer diameter of the cable can be made uniform, improving the appearances of the cable after erection while improving the workability in erection by virtue of simplification of erection clamps, vibration control clamps, vibration control dampers, etc.

摘要： PURPOSE:To obtain a colored cable by bonding a colored fluororesin through an adhesive to a polyolefin resin layer as a sheath or a corrosion-protection layer of a cable for cable-braced bridge, etc. CONSTITUTION:The outermost sheath or corrosion-protection layer of the colored cable has a double extrusion-coating layer structure composed of a polyolefin resin layer and a colored fluororesin layer and containing a primer composition for fluororesin between the layers as an adhesive to bond the polyolefin resin layer to the fluororesin layer. The surface of the polyolefin resin layer is heated before or after the application of the adhesive to the polyolefin resin layer and the layers are bonded with each other by extrusion- coating the fluororesin layer to the polyolefin resin layer while keeping high surface temperature.

摘要： PROBLEM TO BE SOLVED: To prevent the increase in transmission loss by addition of a tension exceeding an allowable range to an optical cable and crushing of the optical cable by setting the outer diameter of the optical cable to not more than the tangent of a triplex CV cable (CVT cable) and setting the stranding pitch of the CVT cable and the optical cable to a specified value or less. SOLUTION: The outer diameter of an optical cable 2 is set to not more than the CVT tangent of a CVT cable 1, and the stranding pitch of the CVT cable 1 and the optical cable 2 is set to 20 times or less the layer core diameter of the CVT cable 1. One to three optical cables are arranged in three stranded valley parts formed in the CVT cable. In the manufacture and laying of an optical composite CVT cable, prevention of the excessive tension of the optical cable and the crushing by falling of the optical cable between the CVT cable wire cores are prevented. When the stranding pitch of the cable is excessively small, some fear for the economic property and characteristic is entertained.

摘要： PROBLEM TO BE SOLVED: To provide a method for manufacturing efficiently cross-linked polyethylene insulation power cable which enables a circular shape to be well maintained on the premise of a fan-shaped conductor which enables an outer diameter to be lessened. SOLUTION: Three strands of fan-shaped cross-linked polyethylene insulation power cable 1, wherein a fan-shaped conductor having no preshape is coated by extruding cross-linked polyethylene thereon and further a plastic sheath as a coating is applied thereto by extrusion, are stranded together so as to be finished into a circular cross-section shape and thereafter are annealed with the said stranded circular shape left as it is. When there is a case where the shape is deformed after stranding before annealing because rigidity of an insulating material is strong, the stranded shape is prevented from being deformed by a binder tape 2 for binding at the time of stranding. An adhesive agent or a thermosetting resin, in place of the binder tape 2, may be applied among cable cores.
