Description
Technical Field
[0001] The utility model relates to the field of cables, in particular to a substation sandwich cable laying device. Background Art
[0002] Laminated cable is a cable with a special structure. It is usually composed of two layers of insulating material with a metal foil or braided shielding layer sandwiched between them. It can provide better shielding effect and reduce electromagnetic interference and signal leakage. Laminated cable is often used in occasions that are sensitive to electromagnetic interference, such as data transmission systems, communication equipment and other fields.
[0003] The main reason why sandwich cables are used in substations is because they have good shielding effect and signal transmission characteristics. In high-voltage power facilities such as substations, there are a large number of electromagnetic interference sources, such as high-voltage power lines, transformers, etc., which can easily cause interference and leakage to signal transmission.
[0004] The metal foil or braided shielding layer of the sandwich cable can effectively suppress the impact of these interference sources on the signal and ensure the stability and reliability of data transmission. Therefore, the use of sandwich cables in substations can ensure the quality of signal transmission, improve the stability of the system, and reduce the possibility of failure.
[0005] The authorization announcement number is: CN211629784U. The utility model discloses a substation interlayer cable support, including a fixed seat, a plurality of side frames are arranged above the fixed seat through a plurality of main frames, a cover is arranged at one end of each side frame through the side frame, and a wire drum is arranged on the upper surface of each side frame. The utility model fixes the fixed seat to the ground in the substation through bolts and threaded holes. When laying cables, a pile of cables can be dispersed, and the heat generated during later use is also easier to disperse. At the same time, each cover is stuck on its own wire drum, fixed by a No. 1 magnet and a No. 2 magnet, and fitted in the inner circle of each wire drum through an anti-slip plate. In this way, each cable is less likely to detach from the wire trough, ensuring that the cables will not be entangled. The entire support is more inclined to disperse a pile of cables at equal intervals and no longer entangled, thereby helping to quickly disperse the heat generated by the cables, having a certain heat dissipation function, and ensuring that the cable support is more stable and not easy to move.
[0006] The device is fixed by using No. 1 magnet and No. 2 magnet, and is fitted into the inner circle of each cable reel through an anti-drop plate, so that each cable is less likely to fall out of the cable trough, ensuring that the cables will not be entangled. The entire bracket is more inclined to disperse a pile of cables at equal intervals and no longer entangled, thereby helping to quickly dissipate the heat generated by the cables, having a certain heat dissipation function, and ensuring that the cable support is more stable and not easy to move.

It is inconvenient to adjust the height according to the environment, which leads to certain limitations for users during maintenance, thus creating certain risks.
