High voltage insulation and bushing design for flexible superconducting cables
Abstract
Design details are presented for the high voltage insulation and feedthrough bushing for a flexible, superconducting, helium-cooled, 138 kV power transmission cable. The cable when installed will have helium at 15 atmospheric pressure and 6 to 8 K temperature flowing in the hollow cable core. The insulation requirements were met by a dielectric lapped from laminated tapes made from commercially available oriented polyethylenes and polypropylenes. Epoxy bushings were chosen for further development.
