Abstract

Provided in the invention is a flat cable of an elevator. The flat cable comprises metal guide cores, insulating layers, and a protection sleeve layer; and the insulating layers and the protection sleeve layer are made of PVC materials. The cable is characterized in that carbon fiber layers coat the outsides of the insulating layers; and a filling layer is arranged between the carbon fiber layers and the protection sleeve layer, wherein the filling layer is polypropylene added with alpha- alumina. The carbon fiber layers are made of flexible carbon fibers. And a talcum powder layer is arranged between the filling layer and the protection sleeve layer. In addition, the flat cable also contains ripping cords located in the protection sleeve layer. According to the flat cable, on the one hand, the tensile strength of the cable is enhanced and the service life of the cable is prolonged; and on the other hand, the signal transmission stability of the cable is improved and thus safety of the elevator running is improved and the elevator maintenance cost is lowered, thereby saving resources and enhancing the efficiency.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to an elevator flat cable and a preparation method thereof. Background technique [0002] During the operation of the elevator, the elevator cable moves up and down along with the elevator to provide working power for the elevator. The faster the elevator goes up and down, the greater the resistance of the cable, which makes the cable more frequently subjected to pulling force. After that, it may be broken or damaged, resulting in power failure or other functions being affected, and serious casualties may result. In recent years, elevator accidents have occurred frequently, and accidents of casualties have occurred from time to time, and the cables as the accompanying parts of the elevator play a vital role in the normal operation of the elevator. [0003] Since the elevator room is a small and nearly enclosed space, and there are many cables for control, lighting, and fans in the e...
