What Kind of Uses Are There for Aerospace-Grade Data Cables?

Applications for aerospace data cables include fiber channel, Ethernet, USB, DVI, Serial ATA and more.

What Are Some of the Main Things I Should Consider When Choosing Aerospace Wire or Cable?

Like you would do in choosing any wire or cable, you should first consider the primary function of the cable, the environment it will be used in and any challenging conditions it may face. This should include considerations of temperature, potential exposure to liquids, and potential movement the cable may have to withstand. Cables will likely need to function in a wide range of temperatures and pressures and must stay intact through the vibrations and movements involved in takeoff and landing.

Next, you should consider which industry specifications you must meet and make sure that your wire and cable adheres to those guidelines. During your search for industry specifications, you should also consider the quality, performance and safety of the cable.

Considering these things will help you choose the most appropriate cable for your application and could even save you money in the future with respect to replacement and repairs.

Why Is the Weight of Cable So Important in the Aerospace Industry?

Many times, it is a question of performance not only for the specific application but the aircraft as a whole. Although some applications require heavyweight wire and cable to be successful, using lighter-weight wire and cable when possible could increase the speed of the plane. Generally, reducing the weight on an aircraft also reduces its drag and allows it to go faster.

Are There Extra Precautions I Can Take When Choosing Cable for Aircraft That Will Carry Passengers?

You should consider Low Smoke Zero Halogen (LSZH) cables for any manned aircraft. These cables cause minimal damage in the case of a fire. The emit little to no smoke or ash and little to no dangerous gases formed by halogens. This is especially important in enclosed areas that don’t have a lot of ventilation like those in most aerospace wire applications. Minimizing smoke and the release of halogens makes it easier for passengers to see and breathe while they navigate an exit.

What Are Some of the Standards Organizations That Regulate Wire and Cable Used in the Aerospace Industry?

Standards Organizations like the National Electrical Manufacturers Association (NEMA) and the Institute of Electrical and Electronic Engineers (IEEE) create guidelines for the wire and cable that are used in a wide range of aerospace wire applications. Military Specifications and Boeing Material Specifications are also important industry standards you may want to consider.

What Does It Mean When I See an Aerospace Wire and Cable Product Labeled with Both Mil-Spec Numbers and Either SAE or NEMA Specifications?

While Mil-Specs are still viable standards in the industry, select military specifications are being released to non governmental standards. Organizations such as SAE or NEMA are then translating the Mil-Specs into their own standards. Since it is still popular to refer to wire and cable products by their Mil-Spec numbers, the new NEMA or SAE specification sometimes appears alongside the Mil-Spec counterpart. Be sure to double-check all standards to make sure they fit your specific project needs.

What Does "BMS" Stand for? How Many BMS Cable Specs Exist?

“BMS” stands for Boeing Material Specification. Several BMS specifications are in existence. The specification covers products ranging from databus cable to aerospace optical fiber cable. BMS cables vary in type, insulation, conductor, shield, jacket material, temperature rating, etc. Learn more about the BMS cables available from Allied Wire and Cable.

Do You Carry In-Flight Entertainment Cables?

In-flight entertainment cables are used to keep flyers occupied with all their entertainment needs such as internet access and other communications. These cables are specifically designed for airplanes with a lightweight design, the ability to withstand the added stress from air pressure, landing and takeoffs and can withstand up to 200 degrees Celsius. Allied Wire and Cable stocks DataMaster® Cable, which includes network quad cable, data cable and network twisted pairs cable. Take a look at our in-flight entertainment cables!

What Is Raychem Spec 44??

Tyco Raychem Spec 44 was manufactured by Raychem, which was bought out by Tyco and is now called TE Connectivity. This aerospace cable was originally designed for military and aerospace wire requirements only; today, it is now used more widely. Raychem Spec 44 wire features a dual-wall construction, low-smoke generation, a temperature range up to 150 degrees Celsius and rated from 600 to 2500 volts. This entire group of Raychem wire Spec 44 also directly crosses to Mil-W-81044 Mil-Spec wire and NEMA WC 27500 Mil-Spec cable. View the full Raychem Spec 44 Line.

Is Allied Wire and Cable Affiliated with Any National and/or International Aerospace Organizations?

Allied Wire and Cable has been a certified member of the National Business Aviation Association (NBAA) and the Helicopter Association International (HAI) since 2016.

The NBAA is an organization that represents companies that rely on aviation. The NBAA includes more than 11000 companies and provides services to businesses in the aviation community. The HAI is a not-for-profit organization that provides services, support, and programs that help advance the helicopter community. Over the past 60 years, HAI has helped members fly more than 5000 helicopters and has also provided safety training and economic viability.
