AbstractIn the future space systems like SSPS, high voltage power transmission on the systems will be required in order to reduce the power loss and the weight of the wires. For the operation of the power transmission with high voltage, highly reliable insulation design of the power transmission wires is required. So we evaluated the insulation performance of SPEC55 ETFE insulated wires for space use in vacuum. The breakdown voltages of the ETFE insulators were measured by DC voltage application. We obtained the results that the breakdown of ETFE insulator occurred at the electric field of about 120-140 kV/mm on the conductor surface of the wires. We also tested the wires with defects of ETFE insulators. The discharge voltage between the exposed conductors was lower than the breakdown voltage of the ETFE insulator and was influenced by the pressure. Low energy electron beam was also irradiated to the wire applied with DC high voltage. Although the breakdown of the ETFE insulator did not occur, partial discharges were detected due to electrons deposited on the surface of the ETFE insulator.
