HTS Cable Multiplying Grid Capacity

• User Benefits
• Higher Power Capacity - 3-5 x Conventional
• Smaller right of way - easier siting/retrofits
• Avoided construction - cost savings
• Lower voltage - substation elimination
• More environmentally acceptable - no oil

Power Cable Retrofit

• Higher power density, lower cooling requirement,
  oil free
• Retrofit of 400' (120 m) of three3-phase copper
  underground cables with a single 3-phase HTS
  underground cable
• Carries the same 2.4 kA total current at 24 kV
  (100 MVA) as the original copper cables and
  leaves 2/3 of conduit space available for future
