Photoelectric composite flat cable used for elevator

Abstract

The invention discloses a photoelectric composite flat cable used for an elevator. The cable comprises 35 conductors, two optical fiber bundles and insulating layers. The outer sides of the conductors and the optical fiber bundles are wrapped by the insulating layers respectively. The 35 conductors are wrapped, insulated and then stranded into groups of core bundles (5 groups in total), and each group of core bundles has seven conductors. The five groups of core bundles and the optical fiber bundles are parallelly arranged in a line, and stranded steel wires are added for reinforcement, after that, an inside liner and an armor layer wrap the outer side. The armor layer adopts galvanized steel wires, the wrapping overlapped rate is not less than 60%, and the outer side of the armor layer is wrapped by a high-flame-retardant nitrile rubber sheath layer. The photoelectric composite flat cable meets performance indexes of low smoke, no halogen, flame retardancy, warp resistance, and shock prevention which are required by elevator cables, and also solves the problem of photoelectric integration.

Description

technical field [0001] The invention relates to the cable industry, in particular to a photoelectric composite flat cable for elevators. Background technique [0002] Elevator cables are cables laid and used in the elevator operation system. The main function is to transmit power for the daily operation of the elevator. Due to the actual special use environment, elevator cables are generally flat and have good flexibility and mechanical strength. They are suitable for elevators. Running status back and forth. [0003] my country's elevator cables began to be developed and developed as early as the 1990s. Under the upsurge of real estate and elevator industry development, many domestic enterprises and factories have begun to develop elevator cables. However, the structural design of cables is relatively simple. With the development of the times, higher requirements such as environmental protection have also put forward specific requirements for the environmental protection ...

Problems solved by technology

However, the structural design of cables is relatively simple. With the development of the times, higher requirements such as environmental protection have also put forward specific requirements for the environmental protection characteristics and multi-functional integration of elevator cables.

[0004] The traditional elevator cables have always been difficult to solve the problems of anti-distortion and anti-vibration in the actual working environment
