THREE-PHASE MEDIUM VOLTAGE
AC Superconducting Cable
The cable that moves power across the campus and into the AI data center’s rectifier. It carries 13.8 kV into the rectifier; on grids and campuses it runs at 10, 35 and 110 kV — always with far more current than copper of the same size.
Three superconducting phases, liquid-nitrogen cooling at 77 K (−196 °C), and built-in temperature sensing — in one compact cable.
Where it is used. AI data-center campus and building feeders and the AC feed to the rectifier; urban distribution where corridor space is tight; and substation and in-plant links to transformers, generators and inverters.

Very low AC loss
A coaxial three-phase design and superconducting shielding keep 50/60 Hz losses low.
More current, same size
Carries 10–20× the current of copper of the same diameter.
Compact route
Far fewer, far slimmer cables mean smaller trenches and less civil work.
Low external field
Coaxial structure and shielding keep stray magnetic field low near sensitive electronics.
800 V DC TO THE RACKS
DC Superconducting Cable
The cable that carries 800 V DC from the rectifier out to the AI data center’s rows and racks, with almost no loss. In its superconducting state its DC resistance is effectively zero — so the cable body wastes almost no power and gives off almost no heat.
Near-zero DC resistance
The cable body wastes almost no power and produces almost no heat to remove.
Cheaper than AC HTS
No AC loss and a simpler build make it at least 10% cheaper than an equivalent AC cable.
One cable, not a busbar farm
A single slim cable replaces massive machined copper busbars to the racks.
Where it is used. 800 V DC to AI racks and DC campus backbones; industrial DC such as electrolysis and metal smelting; and connections to rectifiers, energy storage and other DC loads.
Cooling included: a closed-loop 77 K package keeps the cable superconducting, with full instrumentation and N+1 redundancy.
