Problems solved by technology
[0002] Cable is the carrier of power transmission, and its use scenarios are very broad, which also makes the requirements for cable performance different in different application scenarios. Especially in the environment where elevators are used, existing cables face many problems during use. Problems, such as small mechanical stress, the cable is easy to be stretched or broken during the suspension and bending process, which affects the service life of the cable and the stability of signal transmission

The present invention proposes a flat cable for an elevator, which includes multiple cables and a flat sheath; multiple cables are spaced apart from each other and vertically placed in the flat sheath, and the axes of all the cables are on the same plane. The cables include The cable core, the wrapping layer covering the outside of the cable core, and the polyester fiber reinforcement layer covering the outside of the wrapping layer; the cable core includes multiple wires and an elastic core, and multiple wires are twisted around an elastic core , the wire includes a conductor in the middle, an insulating layer covering the outside of the conductor, and a shielding layer covering the outside of the insulating layer; there are also two first strengthening cores and multiple second strengthening cores in the flat sheath, and two The first reinforcing cores are respectively located on both sides of the plurality of cables and arranged in the axial direction, the plurality of second reinforcing cores are arranged in parallel and longitudinally, and each second reinforcing core is located between two adjacent cables. The flat cable for an elevator proposed by the invention is resistant to tension and pressure, and is suitable for long-distance suspension.
Description
technical field [0001] The invention relates to the technical field of cables, in particular to a flat cable for elevators. Background technique [0002] Cable is the carrier of power transmission, and its use scenarios are very broad, which also makes the requirements for cable performance different in different application scenarios. Especially in the environment where elevators are used, existing cables face many problems during use. Problems, such as small mechanical stress, the cable is easy to be stretched or broken during the suspension and bending process, which affects the service life of the cable and the stability of signal transmission. The above problems need to be improved urgently. Contents of the invention [0003] In order to solve the technical problems in the background technology, the present invention proposes a flat cable for elevators that is resistant to tension and pressure and is suitable for long-distance suspension. [0004] A flat cable for a...
