Can the ground cable be put together with the communication cable?
No, please.First, the grounding cable power cable is still referring to what, whether the power cable or control cable are grounding protection, electro magnetic, magnetic power is the law of things, it is suggested that individual communication cable laying, can effectively avoid the interference caused by the magnetic field control system fault.
(1) the power cable and the line of the weak current (60V or less) system (especially the communication line) shall maintain the maximum distance as far as possible.(2) the power cables of the same circuit shall be closely arranged.(3) the three-phase cables are configured with equilateral triangle.(4) winding or complete transposition of all live wires in the same circuit.(5) as far as possible the use of multi-core power cable, the same circuit all phase conductor, neutral conductor and ground wire in the same cable.
The layout of cables affects the mutual spatial relation of cables. The spatial relation will affect mutual inductance impedance, and mutual inductance impedance has zero sequence mutual inductance impedance and positive sequence mutual inductance impedance. If the distance is larger, zero sequence mutual impedance becomes small, helps to reduce the interference; positive mutual impedance depends on the power cable and interference ratio line distance, the ratio is close to 1 by interference lines and each phase of power cable the distance is smaller, the interference, if the end distance (such as the ratio is 1), there is no positive (negative) sequence mutual impedance.
