【Abstract】 The performance of helium leak tight composite axial insulation breaks for experimental advanced super-conducting Tokamak(EAST) magnet system was tested in details.Test results show that the composite axial insulation breaks can endure DC/AC voltage higher than 30 kV,even to 45 kV in lower temperature.The leak rate of insulation breaks is less than 10-9 Pa·m3/s under 10 MPa pressure at liquid helium temperature and the cryogenic performance keeps fairly good under maximal outside forces in tensile and bending test.All test results indicate that the integral performance of axial insulation breaks meet EAST technical requirements.更多还原
