Arc-Tracking, Wire Insulation-Pyrolization, and Current-Derating Vacuum Facility

[horizontal rule]

Description:[Vacuum Facility]

  • Evaluates pyrolization and arc tracking of insulated wires and current limitation of insulated wires under various thermal space environments.
  • Vacuum bell jar uses the cryogenic pump for high-vacuum capabilities.
  • Power includes 600 A electric arc welder, three 300 V, 6-a dc power supplies, and 240 to 400 kHz ac power supply.
  • 50 MHz EISA computer for real-time data acquisition, process control, and computation.
  • Sufficient feedthroughs available to provide cooling, thermocouples, and high current to test area.
