The Cryodynamics electrical Power Feed Cable System is specially designed to be submerged in cryogenic liquefied gases and remain flexible at minus 200 degrees Celsius. The cables have been formally tested and accepted by Underwriter's Laboratories (UL) and listed as Power Feed Cable for Liquefied Gases ±200 degrees Celsius.

The cables are TFE insulated and are protected by braided stainless steel armor. They are UL approved for use with supply voltages up to 8000 VAC. Sizes range from 4 to 250 AWG/KCMIL, with a maximum amperage of 732 amperes per single conductor at -256 degrees Fahrenheit (-160 degrees Celsius).
