Space-Rated Wire Built for the Harshest Environment Known
ASW Space Cables: Radiation-Hardened, ECSS-Compliant, Flight-Ready
Gore ASW-series space-rated cables combine radiation-resistant ePTFE insulation with ECSS-compliant low-outgassing materials, engineered to survive the extreme thermal cycling, vacuum, and radiation environment of orbital and deep-space missions.

ASW-series space-rated cables with radiation-resistant ePTFE insulation, engineered for the extreme thermal cycling and outgassing requirements of space missions. The ASW series provides reliable electrical signal transmission across the harsh conditions of launch, orbit, and deep-space operation.
Why Choose Gore ASW Space Wire Cables?
Radiation Resistance Without Mass Penalty
ePTFE insulation provides inherent radiation resistance to total ionizing dose (TID) and proton fluence levels encountered in LEO, MEO, and GEO orbits. Unlike radiation-hardened polymers that add mass, Gore's ePTFE maintains these properties at low density — critical for mass-constrained spacecraft where every gram of harness weight has a launch cost.
ECSS-Compliant Low Outgassing
Material outgassing in vacuum deposits contamination on optical sensors, solar panels, and thermal control surfaces — potentially mission-ending failures. ASW cables meet ECSS-Q-ST-70-02 outgassing requirements, ensuring that the harness materials will not contaminate sensitive spacecraft systems throughout the mission lifetime.
Extreme Thermal Cycling Durability
Satellites in low Earth orbit experience temperature swings of over 200°C in each 90-minute orbit — thousands of cycles over a mission lifetime. Gore's ePTFE insulation and specialized jacket materials maintain flexibility and electrical performance across -180°C to +200°C without cracking, delaminating, or stiffening in ways that could fatigue conductors at attachment points.

Frequently Asked Questions
What radiation environments are ASW cables qualified for?
Gore ASW cables are designed for the radiation environments encountered in typical LEO, MEO, and GEO missions. Specific total ionizing dose (TID) tolerance and proton fluence data is available in Gore's space cable documentation, which RSTECH can provide upon request.
How do I verify outgassing compliance for my mission's contamination control plan?
Gore provides material outgassing data per ECSS-Q-ST-70-02 methodology (TML and CVCM values) for ASW cables. These values can be incorporated directly into spacecraft contamination control analysis. RSTECH can supply the material certificates required for flight documentation packages.
Are ASW cables available with space-qualified connector terminations?
Gore ASW cables can be supplied as raw cable or as terminated assemblies. For space applications, termination to DSUB, Micro-D, SMA, or custom space-grade connectors is available. Contact RSTECH with your harness drawing requirements.
What is the lead time for space-grade cable procurement in Israel?
Space-grade cable procurement typically requires longer lead times than commercial products due to material traceability and documentation requirements. RSTECH Electronics recommends early engagement — contact us at program definition phase to plan procurement timelines.
