The aerospace industry operates in one of the most demanding environments on Earth—and beyond. From commercial airliners cruising at 35,000 feet to satellites orbiting the planet, every component must withstand extreme temperatures, intense vibrations, radiation exposure, and strict weight constraints. Cables, as the “nervous system” of aerospace vehicles, play a critical role in transmitting power, data, and signals between avionics, engines, navigation systems, and communication modules. This raises a key question for engineers, procurement teams, and industry professionals: Can machine cable, a product traditionally designed for industrial machinery, be adapted for use in aerospace applications?
Before evaluating machine cable’s suitability, it is essential to understand the non-negotiable standards that aerospace cables must meet. These requirements are far more stringent than those for industrial machine cables, driven by the need for safety, reliability, and long-term performance in harsh conditions:
Aerospace cables face temperature fluctuations that range from -65°C (-85°F) in high-altitude flight to 200°C (392°F) near engine compartments or during re-entry. In satellite applications, temperatures can plummet to -150°C (-238°F) in the shadow of Earth or rise to 120°C (248°F) in direct sunlight. Industrial machine cables, by contrast, are typically rated for -40°C to 105°C—insufficient for most aerospace use cases without modification.
Satellites and spacecraft are exposed to ionizing radiation (e.g., gamma rays, cosmic rays) that degrades standard cable insulation over time, leading to signal loss or short circuits. Additionally, aerospace cables must resist exposure to jet fuel, hydraulic fluids, ozone, and humidity—substances that can break down the PVC or rubber insulation commonly used in machine cables.
Every gram matters in aerospace design: reducing weight improves fuel efficiency for aircraft and extends mission life for satellites. Aerospace cables must be lightweight yet durable enough to withstand constant vibration (e.g., from jet engines) and mechanical stress during takeoff, landing, or launch. Industrial machine cables, often built with thick, heavy insulation for rugged factory use, fail to meet these weight-to-strength ratios by default.
Aerospace systems have zero tolerance for cable failures. A single faulty cable could lead to avionics malfunctions, communication blackouts, or even catastrophic accidents. As a result, aerospace cables must comply with strict industry standards, including DO-160 (published by RTCA, Inc., for aviation environmental testing), IEC 60332 (fire resistance), and AS9100 (aerospace quality management). Machine cables, designed for factory floors where downtime is costly but not life-threatening, rarely meet these certifications out of the box.
Machine cables are engineered for industrial environments, where they power and control machinery like conveyor belts, robotics, and manufacturing equipment. Their core features include:
At first glance, these traits seem incompatible with aerospace demands. However, modified machine cables—engineered to address temperature, radiation, and weight gaps—can serve as a viable solution for certain aerospace applications.
To make machine cables suitable for aerospace environments, manufacturers must modify three key areas: materials, structure, and testing. These adjustments bridge the gap between industrial performance and aerospace compliance.
The biggest limitation of standard machine cables is their insulation and jacketing materials. To meet aerospace requirements, these materials must be replaced with high-performance alternatives:
For example, a standard machine cable used in a factory robot might have PVC insulation and a copper conductor. Its aerospace-modified counterpart would use PTFE insulation, a silver-plated copper conductor, and an FEP jacket—transforming it into a cable capable of operating in a commercial airliner’s avionics bay.
Aerospace cables must be lightweight, so manufacturers modify machine cable structures to remove unnecessary bulk:
No modified machine cable can enter the aerospace market without passing stringent testing. Manufacturers must validate performance against standards like DO-160, which includes:
Only after passing these tests can a modified machine cable be considered “aerospace-grade.”
Modified machine cables are not a one-size-fits-all solution for aerospace, but they excel in specific use cases where their industrial roots (flexibility, durability) are combined with aerospace upgrades. Below are three key applications:
Modern airliners like the Boeing 787 or Airbus A350 rely on complex avionics systems to control navigation, communication, and passenger entertainment. These systems require cables that are flexible (to fit in tight spaces), EMI-resistant (to avoid signal interference), and temperature-tolerant (to withstand cabin and equipment bay conditions). Modified machine cables—with PTFE insulation, compact stranding, and foil-braid shielding—are ideal here. They are more cost-effective than fully custom aerospace cables while meeting DO-160 standards for vibration and temperature.
UAVs (drones) used for military surveillance or commercial mapping operate in diverse environments, from desert heat to arctic cold. Their cables must be lightweight (to extend flight time) and durable (to withstand crashes or rough landings). Modified machine cables, with their lightweight FEP jackets and flexible stranded conductors, are a popular choice for UAV power and data transmission. They also meet the military’s MIL-STD-810 standards for environmental resistance.
While satellite in-orbit cables require the highest-grade materials (e.g., radiation-resistant PTFE), ground systems (e.g., tracking antennas, data processing centers) have less extreme demands. Modified machine cables, with their cost-effectiveness and durability, are often used here. They can withstand outdoor temperatures (-40°C to 85°C) and resist weathering, making them a reliable choice for connecting ground-based aerospace equipment.
When it comes to modifying machine cables for aerospace applications, not all manufacturers have the expertise, equipment, or certifications to deliver reliable results. FRS Factory stands out as a leader in this space, combining decades of experience in industrial machine cable production with a deep understanding of aerospace standards.

This means you get a cable that meets all compliance standards without breaking your project budget.
Can machine cable be used in aerospace applications? The answer is yes—when modified to meet aerospace standards. Standard machine cables are not suitable for extreme aerospace environments, but with material upgrades (e.g., PTFE insulation), structural optimization (e.g., lightweight jacketing), and rigorous testing (e.g., DO-160 compliance), they become a reliable, cost-effective solution for avionics, UAVs, satellite ground systems, and more.
