The Elevator video monitoring cable manufacturer tells you that the monitoring application in elevators must consider the particularity of its continuous up and down movement. The wiring is required to be different from the fixed-point monitoring method of pipe (slot), and it must be with higher mechanical strength and tensile strength. For transmission cables, Elevator video monitoring cable manufacturers tell you that general engineering companies have paid attention to the use of high-strength cables in wiring, but the electrical characteristics of transmission cables have not attracted enough attention, resulting in the widespread existence of elevator interference.

1. Satisfy the tensile strength: Elevator video monitoring cable manufacturers tell you that half of the elevator cables are used for extension. High-rise elevators 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.
2. Good electrical parameters: The Elevator video monitoring cable manufacturer tells you that when the cable moves up and down with the elevator, there will be a section of the cable that is bent and deformed under the action of gravity, resulting in changes in electrical parameters such as cable impedance and distributed capacitance. Elevator video monitoring cable manufacturers tell you that when a cable with poor quality is deformed under stress, the parameters change greatly, which will cause impedance mismatch, increased video attenuation and signal reflection, which will lead to a decrease in the signal-to-noise ratio of the video signal. Video interference, so you should try to use shielded, thick video cable to prevent interference signal "intrusion." Practice has proved that SYWV's coaxial cable is better than SYV, and multi-layer shielding is better than single-layer shielding.
