The hook-up wires used in small satellites and launch vehicles must safely and reliably deliver power to monitor the earth effectively and help us stay connected anytime, anywhere. They must withstand the harshest conditions, like wide-ranging temperatures and atomic oxygen (ATOX). NewSpace private companies also need wires delivered quickly at an economical price to meet demanding program schedules.

At Gore, we combine decades of expertise in materials technology with proven traditional spaceflight heritage to offer a reliable, economical wire solution for the NewSpace industry.


GORE Hook-Up Wires are proven to distribute power with low-frequency signals safely and reliably for the entire mission duration. We design our wires with a combination of robust insulation materials that are proven to resist the most demanding spaceflight and orbit conditions while operating at maximum voltage.

For instance, they resist extreme temperatures ranging from -200°C to +200°C, ATOX and radiation exposure while satellites are in orbit. They also withstand severe shock and vibration during vehicle launches. Even harsh chemicals and undesirable fluids won’t degrade the performance of our robust insulation combination. Unlike alternatives available in today’s market, our hook-up wires help meet mission demands without the need for added protection.

Affordable Price & Fast Delivery

With our comprehensive understanding of products and appropriately scoped NewSpace test procedures, our wires are qualified according to NASA Level 2, ESA Class 2 and TRL 6+. We can also deliver our wires quickly and inexpensively so you can meet demanding program schedules, frequent launch cycles and short satellite missions.

From launch to orbit to re-entry into earth’s atmosphere, GORE Hook-Up Wires ensure lifelong protection and performance so that critical systems can continue functioning at all times.


GORE Hook-Up Wires are engineered to perform reliably in a variety of NewSpace applications, including:

  • DC power distribution
  • electric power supplies
  • microgravity experiments
  • optical instruments

If you have any questions or to discuss your specific application needs, please contact a Gore representative.


GORE Hook-Up Wires provide system architects and engineers with many benefits that improve electrical and mechanical performance such as:

  • safe, reliable power distribution up to 600 Vrms with low-frequency signals
  • robust insulation combination helps meet mission demands without added protection
  • excellent resistance against extreme temperatures, ATOX, radiation and chemicals
  • low-risk product qualified to NASA Level 2, ESA Class 2, and TRL 6+
  • economical solution well-suited for LEO/MEO applications
  • quick delivery to meet demanding program schedules and frequent launch capabilities
  • leverage proven performance with 100% failure-free flight record in hundreds of traditional spaceflight programs
