YFFB elevator accompanying cable refers to elevator power cable and emergency power cable. The YFFB elevator accompanying cable generally includes a ground wire, four twisted-pair shielded wires, and multiple 0.75 multi-core flexible wires. The original accompanying cable of the regular elevator usually has a video cable or a network cable. It is best to ask the elevator worker or manufacturer, or go to the elevator car to check. If it is determined that there is no video cable (this possibility is relatively small), it needs to be re-laid, according to the standard process, and must use a wire with good shielding, otherwise, when the elevator 380V motor is running, it will cause interference to the video signal.

The laying of YFFB elevator accompanying cables should generally meet the following requirements:
 (1) The ambient temperature when laying cables should not be lower than 0 °C. Before laying the cables, check that the specifications, programs, routing and locations are consistent with the design requirements.
(2) The cables should be laid straight, without twisting, looping, etc., and should not be squeezed and damaged by external forces. When fixing, the tightness should be moderate.
 (3) Labels should be attached to both ends of the cable before laying to indicate the start and end positions, and the label writing should be clear, correct and correct.
 (4) Power cables, signal cables, twisted cables, optical cables and cables of other weak current systems in the building should be laid out separately.
The laying requirements of the YFFB elevator accompanying cable are introduced here, I hope it will be helpful to you.
