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). Government and commercial programs also need wires that are reasonably priced and can be delivered on time to meet demanding schedules.

At Gore, we combine decades of expertise in materials technology with proven traditional spaceflight heritage to offer a reliable, affordable wire solution manufactured quickly 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.

Our wires are well-suited for low earth orbit (LEO) and medium earth orbit (MEO) applications -- like optical instruments, electric power supplies and microgravity experiments. When you want an affordable product qualified to NewSpace industry standards and delivered quickly, look no further than proven reliable GORE Hook-Up Wires.


Well-suited for LEO and MEO missions, GORE Hook-Up Wires distribute reliable and safe power with low-frequency signals in a variety of applications, including:

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

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

Features & Benefits

GORE Hook-Up Wires are engineered with unique features that make them more durable against challenging environmental factors and onboard conditions, including:

  • Temperature-, radiation-, abrasion- and ATOX-resistant materials
  • chemically inert and low-outgassing materials
  • smaller, lighter weight wire diameters

Our wires provide system architects and engineers with many benefits that improve electrical, mechanical and environmental performance such as:

  • proven reliable power distribution up to 600 Vrms with low-frequency signals
  • excellent resistance against extreme temperatures, ATOX, radiation, chemicals, more
  • robust insulation combination help meet mission demands without added protection
  • reduced size and weight helps meet challenging mass budgets and tight installation paths
  • affordable solution delivered fast to meet demanding program schedules and frequent launch capabilities
  • low-risk product qualified to ESA Class 2 and NASA Level 2
  • selected complimentary samples with short lead times for prototyping and evaluation
  • leverage proven performance with 100% failure-free flight record in hundreds of traditional spaceflight programs
