Can AC and DC circuits share a single cable?

Simply put, AC and DC circuits cannot share a single cable. The main reason is that both AC and DC circuits are independent systems. When AC and DC share a single cable, AC and DC interfere with each other, reducing the insulation resistance to DC; At the same time, DC is an insulation system, while AC is a earthing system, which is easy to cause short circuit between the two, so AC and DC cannot share one cable
