YFFB elevator accompanying cable is an indispensable part of elevator operation. The accompanying cable is like the human nervous system, which is closely related to human life. The accompanying line is composed of coaxial cable, including steel wire, nylon rope and fibrous tissue. YFFB elevator accompanying cable manufacturers tell you that the outer sheath is made of super soft material, which can effectively improve the tensile strength and flexibility.

Its service life is long, and the video transmission mode is stable, flexible and clear. Due to the narrow space of the elevator, there are many cables for indoor control, lighting, fans, etc., and it is difficult to lay the supporting cables. According to the actual analysis, what principles should be followed in the selection of elevator-specific integrated cables?
1. Meet the tensile strength: half of the YFFB elevator accompanying cable is used for extension, and the maximum height of the high-rise elevator exceeds 100 meters. The weight of a 100-meter cable is close to 100 kg, so the cable must have sufficient tensile strength. At present, there are self-supporting flat panel composite elevator monitoring cables on the market. This cable combines video coax, power lines, data lines, and steel strands to form a flat ribbon cable (flying line). In this way, the tension of the entire cable is borne by the steel wire rope, and the tensile strength is very good, so the signal cable will not be broken due to gravity during the operation of the elevator.
2. Good electrical parameters: When the elevator accompanying cable moves up and down with the elevator, the YFFB elevator accompanying cable will bend and deform under the action of gravity, resulting in changes in electrical parameters such as impedance and distributed capacitance. When a cable of poor quality is deformed by force, its parameters change greatly, which will lead to impedance mismatch, increase video attenuation and signal reflection, resulting in decreased video signal-to-noise ratio and video interference. Therefore, you should try to choose a well-shielded, thick-diameter video cable to prevent the intrusion of interfering signals.
