Abstract
The simultaneous application of the design voltage (20 kVrms) and curr ent (2 kArms) to ethylenepropylene-rubber (EPR)-insulated superconduct ing cable, cooled by liquid helium, was successfully carried out. The superconductor was a niobium layer clad on a copper pipe. The EPR insu lation was extruded simultaneously with semiconducting electrostatic s hielding layers. A specific advantage of this cable design is the comp lete exclusion of the cryogenic helium from the electrical Insulation structure.
