Overview
Increase Reliability with Qualified Space Cables
In the space industry, electronics must be reliable, or safety can be seriously compromised.
GORE Space Cables, Type SPL for geostationary Earth orbit (GEO) applications provide the high-quality signals required in space missions — in a lightweight, small design that makes them ideal for high-volume manufacturing.
The cables are extremely flexible and durable, so they’re easier to install in even the tightest configurations. Crucially, the cables’ lighter weight and small structure reduce the total launch mass of the spacecraft, saving valuable weight for other critical subsystems.
The cables are qualified to ESA specifications ESCC 3901/019.
The Science Behind the Cables
The key to our space cables’ performance is the proprietary material used in their insulation, expanded polytetrafluoroethylene (ePTFE). This specialized insulation increases the cable’s ability to bend and flex, while protecting the conductors from stress and damage. The ePTFE material also eliminates the need to trim frayed insulation, and its specialized construction reduces the overall cable diameter so it fits in the tightest enclosures.
Applications
GORE Space Cables, Type SPL for geostationary Earth orbit (GEO) applications are frequently used for:
- DC power distribution
- low-frequency applications
- optical instruments
The cables have been trusted by many critical spacecraft missions, including:
- Express MD1/MD2
- Globalstar satellite
- MetOp satellites
- XMM-Newton 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.
