Elevator cable

Abstract

The invention relates to a cable, and especially relates to an elevator cable. The elevator cable comprises multiple conductors and an insulator coating the conductors. The insulator is a carbon fiber insulator. Multiple accommodating cavities used for accommodating the conductors are formed in the insulator, the accommodating cavities are independent cavities which are separated from one another and are not intercommunicated, the cross section shape of the cavity body of each accommodating cavity is the same with the cross section shape of the corresponding conductor, and the inner surface of each accommodating cavity closely fits the outer surface of the corresponding conductor. Compared with the prior art, as the carbon fiber material has higher strength and better flexibility than the traditional PVC material, the insulator is effectively prevented from wearing, cracking and aging when the cable is bent, the service life of the whole cable is prolonged safely and effectively, and insulating layers coating the surfaces of the conductors are removed.

Description

technical field [0001] The invention relates to a cable, in particular to an elevator cable. Background technique [0002] The elevator cable, as a cable used to supply power and signal transmission to the elevator when the elevator car moves up and down, needs to have good reliability and stability. [0003] And the structure of elevator cable generally all is to be covered with insulating layer some conductors and the insulator that is coated on every conductor outer surface to constitute at present. And with the development of elevator electrical control technology, the number of cores used to transmit electric energy and signals is decreasing, so that the insulation cores of elevator cables can be combined in more ways to reduce material consumption. However, as the car moves up and down, the elevator cable will bend along with the car, and in order to ensure that the cable can be bent effectively, the material of the insulator and the insulating layer wrapped outside t...

AI Technical Summary

Problems solved by technology

However, because the PVC insulation material in the cable will crack, age and wear after repeated bending, this will cause the conductors inside the cable to be exposed and cause safety hazards, and there will be insulation between two adjacent conductors. The phenomenon of touching the line due to the wear and tear of the material will cause a short circuit during the operation of the elevator

Therefore, maintenance personnel need to check, maintain and replace the cables at fixed points and regularly, thus increasing the use cost of the elevator
