The difference between industrial and electronic wiring harnesses

What is the difference between industrial and electronic medical wiring harnesses? Industrial wiring harness processing and ordinary electronic wiring harness is very different. Industrial wiring harnesses are usually high current, the wire requirements are extremely high. When the alternating current passes through the wire, the current will be concentrated on the surface of the wire, so that the resistance of the wire increases, and the loss of power also increases, which is the skin effect. The higher the frequency of current or voltage change, the more significant the skin effect.

In industrial harness processing, the skin effect is one of the most basic distortion processes in the signal line, and it may also be the most overlooked and misunderstood. The skin effect can be inconsistent in the transmission of high-frequency signals due to different components of the transmitter. Similarly, on old wire harness conductors, the skin effect encourages signal currents to bounce across multiple wire harnesses, creating harsh marks for sound. In order to reduce the skin effect, in the high-frequency circuit is often used to use multiple mutually insulated thin wire woven into a bundle instead of the same cross-sectional area of the thick wire, the multi-strand wire bundle is called braided wire. Using skin effect, the hollow copper wire can be used to replace the new copper wire in the high-frequency circuit to save copper. Although its resistivity will become larger, but does not affect the transmission performance, but also can increase the tensile strength of the transmissionwire.

 Skin effect can be used to surface quench metal in industrial wire harness machining. In addition, skin effect is also one of the methods of electromagnetic mask, which can be used to prevent the penetration of high frequency electromagnetic waves into good conductors to make electromagnetic mask device, which is also the reason for poor cell phone signal in the elevator.
