Abstract
The Superconducting Conductor Testing Facility, which is developed to evaluate the reliability of engineering technology and safe operation in fusion reactor operation environment, is under engineering design by ASIPP. In case of an emergency shut-down like in succession of a quench, the voltage across the coil may rise to about 2.5 kV. The facility has to be reliably insulated. In this study, we present the preliminary design of the insulation system of the Superconducting Conductor Testing Facility, which includes turn and ground insulation. Since the magnet of the facility adopts the manufacturing process of “Wind&React”, the turn insulation material should withstand a heat treatment with temperature up to 650 °C. The insulation system is composed of S-glass fiber reinforced tape and vacuum-pressure impregnated in a DGEBF epoxy system. The mechanical properties are being subjected to investigations with respect to the design requirements and operating conditions. The test results are analyzed to verify the feasibility of the insulation system design.
