Why are aircraft wiring harnesses so expensive and what does this have to do with beer?
Do I need to see a dentist? Do I need to see a doctor? No. In our field of expertise, all you need to do is see an assembler.
A conductor is a type of material that allows the flow of an electrical current in one or more directions. In an aircraft wiring harness these conductors are what power the aircraft and carry data back and forth between components. Some examples of materials that are good conductors include silver, gold, copper, and aluminum.
InterConnect Wiring held a Blood Drive on July 27, 2016 from 9am to 1pm. InterConnect Wiring and Carter BloodCare often work together to put on blood drives to help save lives in the community. This specific drive could easily save 33 lives in the community!
A wire termination is the work performed to the end of a wire that allows it to connect to a device (connector, switch, terminal, etc.). There are many types of terminations in the aircraft industry, but we can boil them down into two basic categories: crimp and solder.
Wire gauge is extremely important to the aircraft that InterConnect Wiring supports. Wire gauge is the measurement of the diameter of a wire, or the thickness of the wire. There are various wire gauges used within UH-60 wiring harnesses, F-15 wiring harnesses, C-130 electrical wiring harnesses, etc.

What comes to mind when contemplating the strength of a wire? A lot of people only consider what can be seen on the outside. For example, how far the wire can be pulled before it breaks or how high of a temperature it can withstand before it melts. But what about breakdowns in the integrity of a wire that cannot always be detected with the human eye? What about a wire’s “electrical” strength?

The highly advanced military aircraft of today, such as the Lockheed Martin F-35 fighter or Boeing B-1 bomber, contain a large amount of specialized electrical equipment. Some examples include relay panels, circuit breaker panels, mux transformer panels, audio panels, navigation computers, weapons computers, and many more. This equipment is essential in enabling the aircraft to complete its designed mission, so it must be able to communicate with each other as well as with the pilot.
In the commercial aerospace and defense industry we find a high concentration of electrical wiring in a relatively small area. The overall goal is to design the equipment and components as small as practical and locate the equipment in a compact, easily accessible area. This includes all wiring harnesses, cable assemblies, and aircraft relay panels. A small space like this is not conducive to minimizing electromagnetic interference (EMI); therefore, to combat the effects of EMI, a metallic shield is placed around the electrical conductors in a wire then coated with insulation, such as TKT.

Did you ever wonder why some wires are bundled together in one aircraft wiring harness and others are not? Why does this wiring harness have 6 break outs while this other harness has only two? Why didn’t the Lockheed Martin, Boeing, or InterConnect engineer just add those two wires to the larger harness? There are several reasons, but one important answer is crosstalk.
