As shown in figure 3, in rolling stock 100, pantograph 101 is on compartment, and the height of storage vacuum circuit breaker etc. is electric Pressure equipment box 102 is under floor.Above-mentioned power transmission cable 1 is used to electrically connect them as extra-high-tension cable.In addition, defeated Electrical cables 1 are used for the power supply from pantograph 101 to other vehicles 100.So the power transmission cable 1 of distribution is in railcar During 100 traveling, distortion is born repeatedly because the activity for following rolling stock 100.For example, when rolling stock slows down, entering When entering bend etc., power transmission cable 1 is followed the activity of rolling stock and is distorted.The durability of the power transmission cable 1 of present embodiment is excellent Different, even if bearing distortion repeatedly, screen layer 6 is also difficult to damage, therefore, it is possible to maintain desired shielding character for a long time.
(effect of present embodiment)
According to present embodiment, with one or more effects as shown below.
In the present embodiment, as the metal wire 60 of the screen layer 6 for forming power transmission cable 1, use and strengthened with high intensity Centered on line 61, the twisted line of twisted after many copper cash 62 is configured around it.Although high intensity line feeder 61 is than leading to 62 intensity are high, be difficult to bend, but by the heart yearn as twisted line, can not damage the bendability of screen layer 6 and will maintain Obtain high, and improve durability.In addition, using copper cash 62 by twisting a part for zygonema, bendability can be maintained high, And obtain the electric conductivity to the requirement of screen layer 6.That is, according to twisted high intensity line feeder 61 and the metal wire of copper cash 62 60, excellent electric conductivity can be formed and the screen layer of bendability and excellent in te pins of durability 6.Therefore, the transmission of electricity electricity of present embodiment Cable 1 has desired shielding character and flexibility, even and if bear distortion repeatedly, screen layer 6 is also difficult to damage, can tie up for a long time Hold shielding character.
For example, as high intensity line feeder 61, with a stainless steel wire of external diameter 0.26mm (TP), as copper cash 62, They will be carried out the metal wire 60 of the external diameter 0.8mm of twisted by the tin annealed copper wire (TA) with six roots of sensation external diameter 0.26mm (area ratio of steel wire is 15%) is wound and forms screen layer 6, possess the screen layer 6 power transmission cable 1 have pass through The durability high of the distortion endurancing on the basis of the 5.4.3 of JRIS J1000.
Specifically, it is thus identified that reversed with distortion angle ± 90 ° in the sample of the length 1mm that will be cut from power transmission cable 1 When, even if number of twists is more than 500 times, screen layer 6 is not also damaged, and is able to maintain that shielding character.
In contrast, confirming situations below, i.e., by the metal wire 60 for constituting screen layer 6 it is altered to the plating of external diameter 0.6mm Tin annealed copper wire, when distortion endurancing is carried out, when number of twists is more than 500 times, broken string is produced in screen layer 6, it is impossible to Maintain shielding character.
In addition, the metal wire 60 containing high intensity line feeder 61 not only has patience to distortion, also just there is patience to bending. Therefore, even if in the case where power transmission cable 1 bears alternating bending, screen layer 6 is also difficult to damage, and can for a long time maintain shielding special Property.

On the other hand, below 1.0mm is set to by by the external diameter of metal wire 60, screen layer 6 can obtain expecting intensity high, moreover it is possible to Obtain appropriate bendability.And, below 1.0mm is set to by by external diameter, the flexibility of metal wire 60 is able to maintain that, therefore Even if forming screen layer 6 with high density winding, braided metal line 60, it is also possible to maintain high by the bendability of screen layer 6. It is exactly that can not damage the bendability of screen layer 6, and makes the density of the metal wire 60 of screen layer 6 high.Thereby, it is possible to suppress exhausted The grade of edge layer 4 deforms due to heating when being crosslinked sheath 7.
Specifically illustrate, in power transmission cable 1, in order to suppress the deformation of sheath 7, sheath 7 is crosslinked with high-temperature In the case of, although temperature when insulating barrier 4, external semi-conductive layer 5 etc. are due to crosslinking will expand, but by screen layer 6 Metal wire 60, expansion is pressed, and then metal wire 60 invades insulating barrier 4 etc. sometimes.The result of intrusion, in the grade conduct of insulating barrier 4 The vestige of metal wire 60 and formed recessed (deformation).When this deformation is produced, due to the distortion of electric field, electric field is easy to focus on A part, therefore the grade of insulating barrier 4 variation, it is easy to destruction insulation.For the point, in the present embodiment, by the outer of metal wire 60 Footpath is set to below 1.0mm, improves the density of the metal wire 60 of screen layer 6 such that it is able to the gap reduced in screen layer 6, suppression The intrusion of the grade of insulating barrier 4 during system crosslinking.
The area ratio for forming the section that metal wire 60 is preferably accounted for high intensity line feeder 61 of metal wire 60 of screen layer 6 is Less than 5%~60% mode twisted high intensity line feeder 61 and copper cash 62 and constitute.Contain height by with this area ratio Intensity line feeder 61, screen layer 6 with high level and can deposit the durability brought by high intensity line feeder 61 and by the band of copper cash 62 The electric conductivity and bendability come.
In addition, screen layer 6 is configured to the twisted of metal wire 60 multiple copper cash 62 and surface area becomes big, therefore according to the skin effect that becomes Should, electric current is readily flowed, and shielding character is excellent.
