Overview

In the space industry, electronics must remain reliable for the duration of the mission. Reliable electronic controls require effective shielding and constant, high-quality signal integrity, along with a relatively low weight to reduce the mass of the spacecraft at launch.

GORE Space Cables, Type SPLD 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. These cables offer the same design and functionality as GORE Space Cables, Type SPL, but with an additional drain wire that eases the termination of the wires onto contacts.

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 3901/021.

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 SPLD 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 Envisat and XMM.

Features & Benefits

GORE Space Cables, Type SPLD for geostationary Earth orbit (GEO) applications feature a:

  • low launch mass
  • small diameter
  • high temperature range
  • high flexibility
  • drain wire that eases termination onto contacts

These features benefit manufacturers by providing:

  • reliable signal integrity
  • surplus mass to be used for other critical subsystems
  • long-lasting product life resulting from robust design
  • reduced installation and maintenance costs without compromised performance

Additionally, Gore’s worldwide engineering team provides sales and technical support. If you have any questions about the space cables’ features or benefits, please contact us
