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:

  • outstanding performance from proprietary hybrid insulation
  • excellent ATOX resistance
  • improved installation with easier crimping, greater flexibility and tighter bend radius
  • valued reliability delivered from an ESA-qualified and a DIN EN ISO 9001:2008-certified manufacturing facility
  • qualification for ESA/SCC 3901/017

Additionally, we offer sales and technical support from Gore’s worldwide engineering team. If you have any questions about the features and benefits of our space cables, please contact us
