Information

The manufacturer of Elevator video monitoring cable tells you that the monitoring application in elevators must consider the particularity of its constant up and down movement. It is required that the wiring is different from the way of pipe (groove) for fixed point monitoring. Transmission cables, Elevator video monitoring cable manufacturers tell you that general engineering companies pay attention to the use of high-strength cables in wiring, but the electrical characteristics of transmission cables have not been paid enough attention, resulting in widespread elevator interference.

The manufacturer of Elevator video monitoring cable tells you that because the elevator car is a nearly closed space, and there are many cables such as control, lighting, and fans in the elevator car, the wiring of the video cable will be more difficult. According to the actual analysis, the selection of cables in elevator monitoring The following principles should be followed.
1. Meet the tensile strength: Half of the elevator cables are used for extension. The high-rise elevator can reach up to more than 100 meters. The weight of a 100-meter cable is nearly 100 kilograms, so the cable must have sufficient tensile strength. Elevator video monitoring cable manufacturers tell you that there are self-supporting flat composite elevator monitoring special cables on the market. This cable combines video coaxial cable, power cable, data cable and steel strand to make a flat Ribbon cable, so that the tensile force of the entire cable is borne by the steel strand, the tensile strength is very good, and the signal cable will not be broken due to gravity during elevator operation.
2. Good electrical parameters: Elevator video monitoring cable manufacturers tell you that when the cable moves up and down with the elevator, there will be a section in the middle that will bend and deform under the action of gravity, resulting in changes in electrical parameters such as the impedance and distributed capacitance of the cable. When the cable of poor quality is deformed by force, the parameters change greatly, which will cause impedance mismatch, increase video attenuation, and produce signal reflection, which will lead to a decrease in the signal-to-noise ratio of the video signal and video interference, so it should be used as much as possible. Shielded, thick-gauge video cables to prevent "intrusion" from interfering signals. Elevator video monitoring cable manufacturers tell you that practice has proved that SYWV coaxial cable is better than SYV, and multi-layer shielding is better than single-layer shielding.
