How to avoid interference in strong current and weak current wiring

First of all, in principle, strong electricity with a voltage level above 50v cannot go with weak cables.

If you say how far it is,

If the strong current and weak current are bare wires, it needs at least 30cm.

If the high voltage and weak current cables are separated by different pvc pipes (plastic pipes), they should be separated by more than 20cm.

If the high-voltage cable and the low-voltage cable run in different kbg pipes (steel pipes), the interval should be more than 13cm, and the pipes should be grounded.

If we have to go together, the interference cannot be completely avoided and can only be weakened. Then the cable with weak current must be shielded and the shielding layer must be grounded. The shielding layer of the equipment should also be connected with the cable shielding layer and grounded.
