Abstract

A flat elevator cable comprises sequentially from inside to outside: a metal conducting core (1), an insulating layer (2), a protective jacket layer (8); the insulating layer and the protective jacket layer are made of a PVC material; a carbon fiber layer (3) is coated outside the insulating layer; a filling layer (4) is arranged between the carbon fiber layer and the protective jacket layer, and the filling layer is made of polypropylene added with alpha-alumina. The carbon fiber layer is made of soft carbon fibers, and a talcum powder layer (5) is arranged between the filling layer and the protective jacket layer. The flat elevator cable also includes tearing ropes (6), and the tearing ropes are arranged in the protective jacket layer. On the one hand, the tensile strength of the cable is enhanced and the service life of the cable is prolonged; on the other hand, the signal transmission stability of the cable is improved and then the safety of the elevator running is improved, and the elevator maintenance cost is also lowered, thereby resources being saved and efficiency being improved.

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...
