Electrical wires and cables are used everywhere in various aviation techniques - combat and passenger aircraft, helicopters, unmanned aerial vehicles, sports models, rockets, etc. With their help, there are control of entire systems and individuals of the above-mentioned devices. However, the conditions of operation of aerospace wires and cables make some features in their operational characteristics and conditions for their production.
Features of cables and wires
Aviakosmic wires and cables are characterized by their diversity. After all, there are many separate systems in aircraft. And most of them are one way or another for their work use electrical energy. For example, in the domestic aircraft engineering of onboard wires, more than 30 subspecies are used. And if you add here winding wires, control cables, power wires - then this number will increase at times.
For listed categories of cable and conducting products, like ship wires, three parameters are important:
resistance to low and high temperatures, as well as to their sharp drop; the highest reliability of operation; Low mass of the route meter of the product.
As for the temperature, the insulation of various brands of aerospace wires and cables is made of materials withstanding the temperature from - 100 ° C to + 300 ° C and higher. It all depends on the area and location of cables.
In the first case, they are used close to the body of the aircraft, which rises to a considerable height. In the second - when its operation occurs near the engines, where the temperature reaches high values.
The reliability of the wires implies their resistance to vibrations, pressure drops, the effects of various aggressive substances and media. In addition, the cable is supplied with shielding veins that protect them from exposure to an external electromagnetic field. To do this, use isolation from fluoroplastic films, as well as additional copper and other wires for shielding. All this makes it possible to achieve unique performance characteristics from aerospace wires and cables.
Another important factor is the low mass of the route. Since in modern aircraft, the number of wires and cables is calculated by hundreds of meters, the manufacturers try to make them as much as possible in order to alleviate the entire mass of the aircraft. For this purpose, various metals are used - copper, nickel, tin, silver. Once you've logged into the site ( whitehouse-market.com ), it's time to decrypt a PGP message using your private key.
