5 Important Considerations For Building Perfect Aerospace Cable Harnesses – Miracle Electronics

Every electric and electronic product requires
cables to run simple machineries require fewer
cables, while complex machineries require
hundreds of cables connected together to help
the equipment to perform. One such industry that
requires such complex machineries and cables is
aerospace.
Whether it is for commercial aircrafts or
military and defence planes, cables are required
for a variety of applications like power, data,
Ethernet, communication, and more. But, all the
cables to be used within aircrafts need to comply
with all kinds of environmental and safety
requirements so that the aircrafts can safely run
throughout their journey miles away from the
earth. Lets see all the basic considerations
that are required to be made while designing
such aerospace cables. Environmental
considerations Aircrafts, whether commercial or
military, fly through various kinds of
environments. They face all kinds of temperatures
and humidity levels. They encounter heat, cold,
aridity, humidity, high rainfall, fog, and every
other possible environmental condition. The
cables used within an aircraft should be able to
adapt

• to each type of situation, while also working
  efficiently at all times. The cables must also
  be able to withstand smoke and dangerous gases,
  in the event of a fire explosion.
• Weight considerations
• With miles of cables running inside a single
  aircraft, the weight of the wires itself can
  amount to more than a thousand kilogram! Thus,
  the cables must also be designed with weight
  constraints in mind. Lesser the cable weight,
  lesser the weight of the aircraft, and hence,
  greater its speed. Also, the weight of the
  aircraft decides upon the fuel consumption
  which means that lesser cable weight also makes
  the aircraft more economical.
• Labelling considerations
• With miles of cables spread throughout an
  aircraft, and a multitude of them, each
  performing different functions, you cant even
  think of having cables installed without any
  markings. Markings and labelling cables makes it
  easy to identify the cables, especially during
  repairs and replacements. Every aerospace cable
  must thus be smooth and receptive to laser
  marking.
• Overloading considerations
• Aircrafts are prone to face overloading quite
  often. This overload pressure is transferred to
  the cables as well. It is hence very important
  that the cables used within an aircraft are
  capable of maintaining circuit integrity even
  during the event of a current overload
  situation.
• Electromagnetic Interference considerations
• Every aerospace cable is required to meet certain
  electromagnetic interference standards, such as
  
• They must use minimum braided shielding, and
  maximize the foil usage.
• They must use twisted data signal wires to cancel
  out emission fields.
• They must use filtered connectors.
• They must provide grounding at both the ends and
  chassis ground.
• They must shield cable signals and minimize
  transfer impedance.
• You can see how such minute installations within
  an aircraft require such critical considerations
  and decisions to be made. There is so much of
  detailed analysis required to build a cable
  network within an aircraft. This is why you must
  always approach a professional aerospace cable
