Problems solved by technology

[0002] As we all know, the elevator is an indispensable means of transportation in high-rise buildings. It must move up and down frequently, and the cables that provide the working power for the elevator must also move up and down with it. With the development of technology and the needs of people's work and life, Some activities such as communication and monitoring are also required in the elevator. For this reason, the relevant signal lines must be suspended next to the elevator, and the elevator is repeatedly lifted and lowered. During the high-speed movement of the elevator, the wind resistance of the cable is large, so that the cable is frequently pulled. , affect the service life, and because the various lines are too complicated, and these lines have relatively poor tensile properties, after a long period of regular lifting movement, they may break or be damaged, resulting in power failure or shutdown. Consequences of interruption of other related functions

Abstract

The invention discloses an MCA series elevator traveling cable. The MCA series elevator traveling cable comprises a flat outer protective jacket made from a thermoplastic elastic material; a flame retardant layer made from a 90-degree flame retardant polyvinyl chloride material is arranged on the outer surface of the outer protective jacket; an elastic insulating layer is arranged on the inner surface of the outer projection jacket; a plurality of conductor groups are arranged inside the outer protective jacket from left to right; each conductor group comprises five insulating copper-clad steel stranded conductors, the five conductors are arranged in a circle, and elastic filling ropes are arranged among the five conductors; and a shielding layer is arranged on the outer surface of each copper-clad steel stranded conductor. The MCA series elevator traveling cable is simple in structure and reasonable in design, the tensile strength of the conductors is improved, the reliability of thecable in the using process is improved, the flame retardance is high, and the cable has the characteristics of abrasion resistance, environment resistance, weather resistance, corrosion resistance andlow-temperature flexibility.
