Mosaic type outer sheath of elevator cable

Abstract

The invention discloses a mosaic type outer sheath of an elevator cable. The mosaic type outer sheath is characterized by comprising an organic polymer inner layer (2a), an organic polymer outer layer (2c) and an intermediate reinforcing layer (2b) clamped between the organic polymer inner layer (2a) and the organic polymer outer layer (2c), wherein through holes are distributed on the intermediate reinforcing layer (2b); and the organic polymer inner layer (2a) and the organic polymer outer layer (2c) pass through the through holes (3) to be mutually fused and connected so as to form a three-layer mosaic type outer sheath structure. By adopting the three-layer mosaic type outer sheath structure, the intermediate reinforcing layer, the organic polymer inner layer and the organic polymer outer layer exert the mechanical function in a synergism manner, the cable is prevented from being damaged by various external factors, the mechanical strength and the electrical performances of each inside unit can be ensured and the integrative performance of an elevator system can be favored to improve, thereby providing larger design space for manufacturing a novel elevator.

Description

technical field [0001] The invention belongs to the field of electric wires and cables, in particular to an inlaid outer sheath suitable for elevator cables. The elevator cables mentioned above include elevator cables with a flat cross section and elevator cables with a circular cross section. Background technique [0002] Elevator cables are necessary and important components in the elevator system structure. [0003] The elevator cable sheath wraps the cable core. According to the traditional definition, its function is to restrain the inner cable core to a predetermined position, and to protect the cable core from various hazards of external factors. Therefore, the traditional elevator cable sheath, when designing the structure and materials, is arranged according to the above two functional definitions: braiding outside the cable core, extruding plastic or rubber protective layer outside the braiding layer. If the structure is complete and impeccable before the cable i...
