Abstract (en)

[origin: GB2331860A] A high-voltage rotating electric machine comprises windings which include conducting means comprising conductor means and cooling means, the cooling means improving the conductivity of the conductor means, insulation surrounding the conducting means, and an equipotential outer layer surrounding the insulation. In the embodiment, the conducting means comprises a high-temperature superconducting (HTS) cable 2 comprises a support tube of Cu 31 and HTS wires 32 embedded in semiconductive plastics 33. Insulation 4 is spaced away 34 from the HTS, and comprises semiconductive layers 35, 36 and thermoplastics insulation 37. The outer layer 36 acts as a static shield and reduces induced voltage losses. The space 34 allows for expansion and may be filled with semiconductive foam. The layers 35, 36 may be of EPR or EPDM having dispersed carbon. The machine may connected directly to all types of high-voltage networks up to 800kV.
