Why should the strong and weak current wiring be separated?
This is because there is a magnetic field around strong electricity. If the wiring distance of strong electricity and weak electricity is too close, it will affect the signal of weak electricity. The specific performance is as follows: if it is a cable TV line, the signal will not be very clear; if it is a telephone line, the telephone will not be clear. There will be noise; if it is a network cable, the network transmission speed will be affected, and so on.
Therefore, when wiring strong and weak currents, the following distance requirements for strong and weak currents must be followed:
(1) User cables cannot be routed together (bundled) with high-voltage (AC>1000V, DC>1500V) cables. The minimum distance between the terminal of the communication cable and the terminal of the high-voltage cable is 450mm.
(2) Under normal circumstances, user cables should not be routed (bundled) with low-voltage (AC<1000V, DC<1500V) wires. The minimum distance between the terminal of the communication cable and the terminal of the low-voltage wire (in the case of a solid spacer) is 150mm.
(3) The user cable can be allowed to be routed (bundled) with the extra-low voltage (AC<42.4V, DC<60V) wires, and the terminals do not need to be separated.
(4) The user cable should be separated from some harmful equipment (such as: arresters, corrosive fluids, objects with a temperature exceeding 60°C, etc.), and the distance should not be less than 150mm.
(5) The power cable is separated from the user cable wiring.
(6) Separation to prevent noise when low-voltage cables and communication cables cross.

The wiring distance requirements for strong and weak current wiring have been analyzed for everyone, and I hope to have a simple reference for friends who do related work.
