The motion cable can only be bundled with other accompanying cables

It is understood that the video signal cable can be routed from the monitoring center to the pre-reserved video interface of the elevator machine room. Nowadays, with the improvement of people's living standards, the number of people is increasing, and there are more and more buildings with more than 8 floors.

Power supply, control and other monitoring cables, try to use shielded cables to prevent elevator ceilings interference signals from leaking outward. The ground should be insulated from the elevator car, guide rail, etc. The location of the video cable exiting the elevator shaft: The ideal choice should be in the middle of the shaft, because the length of the video cable traveling in the shaft at this time is only a little more than half of the depth of the shaft, the shortest, and the natural interference is the smallest; This kind of qualifying requirements can only be achieved depending on the situation.

The power supply of the camera should preferably be a centralized DC power supply method, followed by the choice of car lighting electricity, not power. I don't know if you know the wiring method of the network cable of the elevator monitoring system? If not, let us take a look at it below.

Cable bundling; here, even if there is a choice of 1 cm, it is necessary to fight for it, because the impact of interference is at least inversely proportional to the square of the distance. Actual engineering may not be allowed. In this case, considering that only half of the cables are moving with the other half, and the other half are only fixed and extended connections, without movement, we call this part 'inactive cables'; this provides a possibility: that half is with the The motion cable can only be bundled with other accompanying cables; the other half of the stationary cables can be routed separately from the accompanying cables.
