Electric power transmission

To transport electric power, HTS cables offer the benefit of being able to transport the same quantities of power within a much smaller cross-section of the conduit, while having additional benefits like a very small magnetic field.

HTS Cables are built as either AC or DC cables. AC Cables typically work at a temperature below of 77K by pumping through sub-cooled LN₂.
DC Cables work around 30K and can thus not be cooled by LN₂ as this will be solid at that temperature. Fluid of choice is pressurized helium gas that is circulated through the cable.

For both cable types Stirling Cryogenics has designed cooling systems concepts that can be built in different sizes to provide the required cooling power of a particular cable design.
