Structure Design and Test Research on the Electrical Properties of High Voltage Instrumentation Cables for the Fusion Reactor

摘要

The HV instrumentation cable is an important route for the signals transmission from the superconducting magnets to the control system, it should be long term operated at around 4.2 K and withstand the high voltage over several dozens of kilo volts during the failure operational contrition, meanwhile the cable should be flexible enough to assemble and arrange to the magnet system. According to the instrumentation cable technical requirement, one new type instrumentation cable was designed, after the electrical properties under high voltage were verified in ASIPP lab, the new type instrumentation cables fully meet the technical requirement.
