Elevator cable

Abstract

The invention provides an elevator cable and belongs to the technical field of cables. The elevator cable solves the problem that an existing cable is poor in anti-interference capacity. The elevator cable comprises a sheath and an optical fiber component. The optical fiber component is sleeved with the sheath. A first shielding layer is arranged between the optical fiber component and the sheath. The optical fiber component comprises a plurality of main lines and a plurality of auxiliary lines. The main lines and the auxiliary lines are evenly distributed on the inner wall of the first shielding layer in a surrounding mode. The outer surface of each auxiliary line is sleeved with a second shielding layer. The sheath is prepared from, by weight, 50-60 parts of polyethylene, 20-30 parts of chlorinated polyvinyl chloride resin, 13-20 parts of chlorosulfonated polyethylene, 20-30 parts of modified polyphenyl epoxide resin, 15-20 parts of silica flour, 2-4 parts of aluminum hydroxide, 1.5-3 parts of magnesium hydroxide, 0.8-1.0 part of t-butyl perbenzoate, 3-4 parts of an anti-aging agent, 0.2-0.5 part of an antioxidant, 1-2.5 parts of a crosslinking agent and 1-2 parts of white carbon black. The elevator cable has the advantages of being convenient to install and high in anti-interference capacity.

Description

technical field [0001] The invention belongs to the technical field of cables and relates to an elevator cable. Background technique [0002] The elevator cables are designed with a special structure and have a long service life, maximizing the operating efficiency of elevator manufacturers. Elevator control cables can provide overall electrical control in the case of long suspension lengths, and at the same time provide monitoring of the elevator. [0003] In the prior art, an elevator cable generally includes an outer sheath layer and an inner reinforcing layer from the outside to the inside, and the inner reinforcing layer is wrapped with a core wire, and the core wire includes an optical cable, an electric cable, and the like. Generally, there are only optical cables or cables in the core wires, and a single optical cable or cable cannot realize the normal operation of the elevator's electrical control and elevator monitoring at the same time, so that in the actual inst...

AI Technical Summary

Problems solved by technology

Generally, there are only optical cables or cables in the core wires, and a single optical cable or cable cannot realize the normal operation of the elevator's electrical control and elevator monitoring at the same time, so that in the actual installation process, it is necessary to use two cables to realize the normal operation and monitoring of the elevator respectively. The monitoring of the elevator increases the cost of materials, and also makes the cable installation inconvenient. The two cables will interfere with each other during work, and even affect the normal operation of the two cables.
