High voltage insulation and bushing design for flexible superconducting cables

Conference ·
OSTI ID:6323676
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 atm. pressre and 6 to 8/sup 0/K temperature flowing in the hollow cable core. The insulation requirements are met by a dielectric lapped from laminated tapes made from commercially available oriented polyethylenes and polypropylenes, and are being tested. Epoxy bushings were chosen for further development. These have been designed and fabricated and are being tested. (LCL)
