Detailed Description

In order to make the above objects, features and advantages of the present invention more clearly understood, the present invention will be further described with reference to the accompanying drawings and examples. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the present invention is not limited to the limitations of the specific embodiments of the present disclosure.

Embodiment 1, as shown in fig. 1, this embodiment provides an elevator trailing cable with a video communication cable 3, which includes an insulating sheath 1 disposed in a flat shape, the flat structure design facilitates bending and has a smaller bending diameter, and is convenient for cable installation and operation, and the cable is not twisted when suspended, for this reason, the existing elevator trailing cable is disposed in a flat shape, as with the existing elevator trailing cable, four sets of core assemblies 2 are disposed in the insulating sheath 1, the video communication cable 3 is disposed at a central position in the insulating sheath 1, the core assemblies 2 are uniformly distributed on two sides of the video communication cable 3, the video communication cable 3 may be an existing commonly-used cable or a cable provided in this embodiment, the video communication cable 3 provided in this embodiment includes a communication cable 31 disposed at a central position, an insulating layer 32 is sleeved outside the communication cable 31, the insulating layer 32 is filled with a metal shielding layer 33, wherein the communication cable 31 is a stranded soft copper wire. The metal shielding layer 33 can effectively prevent electromagnetic interference, and in this embodiment, the metal shielding layer 33 is a net woven by high-density metal wires, the covering density reaches more than 95%, and the metal shielding layer has good tensile strength and bending resistance. The insulating layer 32 is made of high-density polyethylene and has a relatively small dielectric constant and dielectric loss angle.

Because of frequent use in order to solve current cable, and lead to the problem that life reduces, still be provided with the central steel core group 4 that stranded transposition steel core pencil formed in video communication cable 3's both sides, one side of keeping away from video communication cable 3 at core group 2 is provided with the outside steel core group 5 that stranded transposition steel core pencil formed, thus, compare with the structural design of two traditional steel wires, the structural design of transposition is adopted to this embodiment, make it possess higher mechanical pliability, and then the effect of buckling is better, and simultaneously, through the center with the setting of the structure of both sides, tensile intensity has further been increased.
