Type SPP for High-Current Applications
Aboard spacecrafts, power-generating systems rely on their cables — and, therefore, so do space missions. GORE Space Cables, Type SPP for high-current applications are highly reliable, and their robust design is small, lightweight and flexible with a tight bend radius for easy installation in tight spaces.

Catalog: GORE® Space Cables for Traditional Space Applications
Product Selection Guides, 4.33 MB
Due to operating conditions in space that are the harshest imaginable, space programs must have complete confidence that the cables connected to critical systems will continue to perform under that stress. And because repairs are not easy to make outside of planet Earth, these cables must not only be rugged but also boast decades of proven success. That’s where GORE® Space Cables for Traditional Space Applications from W. L. Gore & Associates come into play.
Overview
Improve Power Delivery Among Electrical Systems
Reliable power is essential for a successful mission. The cables that deliver the power are just as critical as the power-generating systems; without reliable cables, the power-generating systems can’t do their jobs.
GORE Space Cables, Type SPP for high-current applications provide the utmost in reliability, and their robust design and copper conductors allow for easy installation in tight spaces. Approved to ESA/SCC 3901/017 specifications and listed on the ESA QPL (Qualified Parts List), our space cables ensure that consistent power is delivered safely and reliably.
The Science Behind the Cables
The key to the outstanding performance of our space cables for high-current applications is the proprietary material used in the cable insulation: expanded polytetrafluoroethylene (ePTFE). We have created a hybrid insulation that makes the cable more flexible and easier to strip. These features make it easier to install the cables without compromising the quality of the power distribution. Additionally, the cables provide outstanding ATOX resistance and function reliably in temperatures ranging from -200°C to +200°C.
Applications
GORE Space Cables, Type SPP for high-current applications are highly reliable and easy to install in:
- manned/unmanned space missions
- high-current power supply
- spacecraft harnesses
- transfer vehicles
Many spacecrafts have relied upon the cables, including:
- ENVISAT satellite
- Galileo satellite
- Globalstar satellite
- INTEGRAL satellite
- XMM space observatory
For more than 25 years, we’ve provided highly reliable cable solutions for the space industry. The 100% success rate of our cables demonstrates our commitment to collaborating with customers when developing reliable and durable cables for these demanding applications.
Features & Benefits
Gore’s Type SPP space cables for high-current applications feature:
- nickel-plated copper conductors
- different gauge sizes for a variety of applications
These features benefit manufacturers and users on space flights by offering:
