Space Cables and Assemblies: High Voltage Power Cables
Extend Product Life for High-Voltage Power Cables
Running cables in a spacecraft is time-consuming and difficult. GORE™ High-Voltage Power Cables reduce the frequency of this task by providing a minimum of 10,000 hours of reliable performance at maximum voltage ratings — ratings that are based on years of test data recorded under actual operating conditions.

Available as hook-up wire, ribbon cable, or round cable, GORE™ High-Voltage Power Cables are specifically designed for applications that require high reliability for long periods of time, such as power supplies and amplifiers, traveling wave tubes, and high-voltage routing.
The Science Behind the Cables
TThe key to the outstanding performance of GORE™ High-Voltage Power Cables is the proprietary material used in the cable insulation — expanded polytetrafluoroethylene (ePTFE). Using this proprietary technology, Gore has developed a specialized Corona-Resistant PTFE. Gas molecules trapped inside the insulation can ionize and cause corona discharge when high voltages are applied, ultimately causing damage to the insulation, which in turn causes more gas molecules to ionize. GORE™ CR-PTFE allows the gas molecules to escape through the membrane without damaging the insulation. Because PTFE fibers are chemically inert and thermally stable, GORE™ High-Voltage Power Cables can be used even at cryogenic temperatures or as high as 300°C for short periods of time.
To protect against the excess gases that occur during ascent into orbit, an additional jacket made of microporous GORE-TEX® fibers can be added to the cables. This jacket allows gas molecules and air to flow completely out of the cable, thereby eliminating the possibility of damage to the cable.
