During launches and missions, reducing the total mass of a spacecraft is essential to add more payload and fit more critical systems and subsystems. W. L. Gore & Associates meets the challenge with the smallest, lightest low earth orbit (LEO) wires and cables qualified to ESCC 3901/026 specifications and registered on the ESA Qualified Parts List (QPL).
SMALLEST, LIGHTEST WIRES & CABLES QUALIFIED TO ESCC 3901/026
Reducing the total launch mass of a spacecraft is a high priority when adding more payload. So wires and cables used for critical systems and subsystems must be as small and light as possible. They must also be flexible enough to avoid damage during installation and strong enough to handle the harshest launch and mission conditions.
Gore offers the smallest, lightest wires and cables for LEO applications without losing mechanical or electrical robustness. They’re qualified to ESCC 3901/026 specifications and registered on the Qualified Parts List (QPL).
REDUCE TOTAL LAUNCH MASS
GORE Space Cables, Type LEW are designed precisely to help reduce the spacecraft’s total mass and make room for more payload and other critical subsystems. They bring unique designs up to 27% smaller in diameter and up to 47% lighter than alternative wires and cables qualified to ESCC 3901/012. For a typical mission, you can save 35% of weight on average in spacecraft using Type LEW’s reduced diameters.
Our low-mass constructions also have more flexibility and tighter bending capability to give you new design and installation options in confined areas of a spacecraft.
PROVEN RELIABLE PERFORMANCE
Besides saving valuable weight, Type LEW is proven to operate continuously up to 600 Vrms while reliably transmitting analog or low-frequency signals from launch through mission duration.
Regarding durability, the robust materials in our wires and cables are chemically inert, thermally resistant and exhibit low outgassing. So they can easily tolerate extreme temperatures, atomic oxygen (ATOX), harsh chemicals and other demanding conditions typically found in LEO environments.
Built to operate reliably and continuously in the harshest LEO environments, GORE Space Cables, Type LEW are ideally suited for several applications, like:
- analog/low-frequency signals
- box-to-box transmission
- power distribution systems
- manned/unmanned space missions

For many decades, Gore has provided reliable solutions in hundreds of global spaceflight programs with a 100% failure-free flight record. We work closely with major space organizations such as the ESA (European Space Agency) and NASA (National Aeronautics and Space Administration) to deliver valued reliability from an ESA-qualified and ISO 9001:2000-certified manufacturing facility.
In 1986, the ESA qualified Gore’s first product for spaceflight. Since then, 10 of Gore’s products have been qualified to ESCC 3901/3902/3408 specifications and 11 are currently registered on the Qualified Parts List (QPL) — including Type LEW.
Our products have been used in many missions over the years, like the iconic 1969 Apollo 11 mission to the moon. They’ve also been used in other well-known programs, like the International Space Station, Space Shuttle Programs, Hubble Space Telescope and many more.
