1. HV-Cables
Current standard product is RG-220/U like cables from Draka. Limited to max. 40kV
Not compatible for CPS SF6 gas filled PFL cable replacement (80kV, 0.3
Several investigation threads:
“Improved” RG220/U for up to 65kV (sample at CERN) standard attenuation
Tests planned: partial discharge measurement TMWS vs. Draka
80kV SF6 gas filled cable replica
80kV low attenuation SF6 gas free cable for 80kV PFL cable replacement
New low attenuation SF6 gas free cable for Tx applications ~40kV
OTS Air insulated RF cables with liquid dielectric
Connectors
Alternative pulse generator concepts (IA, Marx, fast PFN) not covered here.
