Within an industrial setting, noise from EMI can create huge problems. For large load devices using many amps of current, small electrical noise may not be too critical. But when it comes to low-voltage and low-current communication wires, just a small amount of voltage finding its way onto a wire can corrupt data transmissions. Shielded cables can help to protect against that problem.
