Industrial equipment wiring harness processing and ordinary electronic wiring harness is very different. The wiring harness of industrial equipment is usually high current and requires very high wire. When the alternating current through the wire, the current will be concentrated on the surface of the wire flow, so that the resistance of the wire increases, the loss of power also increases, this is the skin effect. The higher the frequency of current or voltage change, the more significant the skin effect.

In industrial equipment wiring harness processing, skin effect is one of the most basic distortion processes in signal lines, and may be the most easily ignored and misunderstood. The skin effect may be inconsistent in transmitting high frequency signals due to different components of the transmitter. Similarly, on old wire harness transducers, skin effects encourage signal currents to bounce across multiple wire harnesses, causing harsh marks for sound. In order to weaken the skin effect, in high-frequency circuits, multiple strands of mutually insulated thin wires are often braided into bundles to replace the thick wires with the same cross-sectional area. This kind of multi-strand wire harness is called braid wire. Using skin effect, hollow copper wire can be used to replace new copper wire in high frequency circuit to save copper material. Although its resistivity will be larger, but does not affect the transmission performance, but also can increase the tensile strength of the transmission line.

The skin effect can be used for surface hardening of metal in industrial equipment harness machining. In addition, the skin effect is also one of the methods of electromagnetic mask, using the skin effect can prevent high-frequency electromagnetic waves from penetrating into the good conductor and make electromagnetic mask device, which is also the reason for poor cell phone signal in the elevator.
