摘要： PROBLEM TO BE SOLVED: To provide a device for preventing bird damage, capable of sustaining bird-repelling effect for a long period. SOLUTION: This device for preventing bird damage is equipped with a guide rail 1, a running gear 2 for traveling along the guide rail 1 and a threatening body 3 attached to the running gear 2. The threatening body 3 is pref. a model of Raptores. It is possible to sustain bird-repelling effect for a long period by making the threatening body 3 rotate in the same way as a weather- cock or by changing the travel speed of the running gear 2 in a state controlled to become irregular.

摘要： PROBLEM TO BE SOLVED: To provide a protective cap for preventing a bolt and a nut from being easily loosened. SOLUTION: This protective cap makes its upper part slim, forms its lower part in a thick cap shape, has a nut insertion hole 2 opened at the lower surface, and is provided with a bolt hole 3 going through from the nut insertion hole 2 to its upper surface, and the cross sectional shape of the bolt hole 3 is formed out of an orbicular part 4 to which a bolt is screwed in, and of a projected part 5 which is expanded from the orbicular part 4 to the outer side. The formation of the bolt hole 3 into a special shape thereby enables the protective cap not to be rotated by the use of usual tools (spanner, wrench and the like).

摘要： PROBLEM TO BE SOLVED: To enable reduction of the height of steel towers and prevention of abnormal transverse swing, by constituting a jumper spacer so that the vertical distance between jumper wires is smaller than the horizontal distance between jumper wires. SOLUTION: The spacer 5 is provided with mounting sections 6 secured on a horizontal member 1, arms 7 extending from the mounting sections 6, and four clamp sections 8 for holding jumper wires 4 formed at the tips of the arms 7. The clamp sections 8 are so constituted that the clamp sections are installed at the tips of the arms 7 extending from the horizontal member 1 located in the center in four directions and the jumper wires 4 are arranged in a rectangle. The vertical distance H between the jumper wires is smaller than the horizontal distance W between the jumper wires. If the distance H is too small, adjacent clamp sections are brought into contact with each other when the clamp sections 8 are opened, and jumper wire clamping is deteriorated. Therefore, the distance must be such a value that the clamp sections can be sufficiently and easily opened. Thus the height of steel towers can be reduced, and further the angle of transverse swing can be reduced.

摘要： PROBLEM TO BE SOLVED: To provide a wire extension sleeve with which a bending load applied to a wire when it passes through a hanging pulley can be relieved. SOLUTION: A wire extension sleeve has a cylindrical main part 1 which has openings at both of its end parts, a steel core compressing unit 2 which is provided in the main part 1 and connects the steel cores of wires which butt against each other in it by compression and a collar 3 which is made of steel and provided between the main part 1 and the steel core compressing part 2. The inner diameters of the neighborhoods of the openings of the main part 1 are gradually increased toward the openings. As the openings are deformed to expand when the sleeve passes through a hanging pulley, a bending load can be relieved so that the opening out between strands of the wire and breakage of strands can be suppressed.

摘要： PROBLEM TO BE SOLVED: To reduce stringing cost by eliminating a jointing metal fitting of special shape, differently from a conventional type in straining wire work, and shortening the length of an insulator string and a jumper wire. SOLUTION: This compressing type strain clamp is formed with a body part 1 which is crimped against an electric wire and a connection flange part 2 formed continuously to the body part 1, whereas the connection flange part 2 is formed with a tool jointing hole to which a straining wire tool B is connectable and an insulator jointing hole 4 jointed to a strain insulator side. One end side of the straining wire tool B is jointed to the tool jointing hole, and by jointing a straining wire means 20 including a semi-metallic wheel and so on, straining wire is conducted for the other side of the straining wire tool B, and under this condition, the insulator jointing hole 4 is jointed to the strain insulator side.

摘要： PROBLEM TO BE SOLVED: To provide safety equipment for preventing accidental fall by which even safety at the time of passing through a spacer can be secured when a transmission line work is executed in midair stunt. SOLUTION: This equipment is provided with two ropes 2L and 2R linked to a main body 1, and keys 3L and 3R are attached at the top ends of respective ropes. One rope is wound around the transmission line at least and the key is linked to the main body so that the ropes are ring-shaped and a worker is prevented from falling. An arm, shield plate 21 and swinging element 23 are pivotally supported on a frame 4 and only one key can be linked to the main body or both the keys can be linked to the main body as well. When only one key is linked to the main body, this key can not be detached without linking the other key to the main body.

摘要： PROBLEM TO BE SOLVED: To eliminate a collision sound produced due to a weak wind by the linking mechanism between a clamp and a spacer in an electrical wire clamp used, for example, for a spacer for overhead transmission electric wire. SOLUTION: A lid part 2 is screwed to a clamp body 1, and a clamping mechanism 4 for retaining the lid part 2 and the clamp body 1 in closed state and a linking mechanism for connecting the clamp body 1 to the spacer are provided. The linking mechanism has linking metal fittings 7 that is inserted into a recess 6 of the clamp body, a pin 8 that penetrates through the metal fittings 7 being inserted into the recess, and a spring 11 that is fitted on the pin 8 and presses the metal fittings 7 in the axial direction of the pin. The metal fittings 7 and the recessed surface of the body 1 contact due to the depressing force of the spring 11, thus preventing a collision sound from being produced.
