Communication cables or cables for power plants should use different routing cables (shafts) to enter the communication room or main control room. What do they mean?
Communication cable and power cable is weak, belongs to, is not allowed to take the same pipe, it is best to use a separate pipeline. The general cable will not affect the signal cable, but the cable inside the reinforcing core damage to conductive.
A communication cable or cable cannot be put together, which interferes with the signal and affects optical communications
I think if the cloth is at the top, there is no heavy cable to press down, and there is casing protection, the mechanical aspect is no problem.Interference, on cable, you use GYFTZY is all metal, so no cable interference problem, nor from the external introduction of lightning current. As long as the shielding layer is properly grounded on both ends of the communication cable, there is no problem.Well, the general is no way to do extra protection, but the tensile strength of communication cable can generally be weight bearing 1km, 1km is the length of the vertical cable hanging down, don't do binding, is no problem, and the height of shaft may not be 1km.So, I think your project is qualified (pay attention to the communication cable, the shield should be grounded at both ends).
Yes, that's what it means. There are four reasons:Communication cable is generally small, and the main cable laying in one ditch, may be crushed.Communication cable requires less interference, and it is easy to be affected by over-voltage and overcurrent interference when it is distributed with the main cable.In the outdoor part of the communication cable is long, the probability of lightning induced overvoltage or lightning is relatively large, connected to the cable and optical cable, optical cable and terminal box, easy to fire fire, so should be isolated from other cables.Convenient for communication line maintenance
