If an aircraft is wired it doesn't mean it has had too much caffeine. Usually wiring relates to electrical and mechanical systems of parts and assemblies. And at SkyGeek, we're rolling out the wire in order to keep you connected.

Besides carrying electrical loads, wires carry with them a simplicity in both form and function. A wire is basically a string of metal that acts as a stranded conductor; since it conducts electricity, it is normally insulated. Wire is a broad term but when it comes in multi-stranded bundles, it has a more precise designation: wire rope (mechanics) and cable (electricity).

Deciding on the right wire can be tricky, but using the following guidelines will facilitate the process. As mentioned, wires are made of metal. Strands are commonly made of steel, Inconel, brass and copper. When selecting one material over another, keep in mind that different metals possess different properties, so for instance, while stainless steel is sturdier than nickel, nickel is more conductive. Other than material, length and diameter should be considered. Buying a roll of wire involves knowing where and how you are using it; if you are using it once or multiple times; and what it is being applied to.

SkyGeek offers a wide range of electrical wire rolls for aviation, automotive and industrial use -- though we specialize in aviation products. Whether you need shielded electrical wire for sensitive systems or high-strength wire for structural tie-downs, we’ve got the selection to support your needs and the prices to support your budget. Our wire is sold by the foot, so you can buy as much or as little as you need, making it easy to save money without sacrificing quality.

From light-duty wires used in avionics to heavy-duty braided electric wire built for demanding environments, we make it easy to find the right product for your project. Each roll is engineered to perform in high-temperature, high-vibration conditions common in aerospace applications.

Frequently Asked Questions About Aircraft Electrical Wire

Q: What type of wire is used in aircraft?
A: Aircraft use specialized aircraft electrical wire designed to handle the demanding conditions of flight. Most aviation-grade wires use copper or tin-plated copper conductors for excellent conductivity and corrosion resistance. These conductors are insulated with high-performance materials such as PTFE, ETFE, or Tefzel®, which protect against heat, vibration, and abrasion. At SkyGeek, we supply aircraft wire that meets strict aerospace standards to ensure reliable performance in every system — from cockpit instruments to lighting and communications.
Q: What is the difference between aircraft electrical wire and aircraft cable?
A: While both are used in aviation, aircraft electrical wire and aircraft cable serve very different purposes. Electrical wire is designed to carry current and power electronic systems within the aircraft, using insulated copper or tin-plated copper conductors. In contrast, aircraft cable (also known as wire rope) is used for mechanical control systems such as flight controls, cargo tie-downs, and safety restraints. In short, aircraft electrical wire focuses on conductivity and insulation, while aircraft cable prioritizes flexibility and tensile strength.
Q: What certifications should aircraft electrical wire meet?
A: All aircraft electrical wire should meet rigorous military and FAA standards to ensure safety, reliability, and consistent performance in aviation environments. Common specifications include MIL-W-22759, MIL-DTL-27500, and M5086/1, each defining conductor materials, insulation types, and temperature tolerances. SkyGeek offers a complete range of certified aircraft wire that complies with these standards, giving maintenance professionals, engineers, and aircraft builders confidence in every installation.
