  • Expanded polymer material for cryogenic applications apparatus and method
    Publication number: 20080248283
    Abstract: A structural and insulating material for cryogenic power transformers uses nonwoven fibers, such as polyester matting, embedded within epoxy made highly porous with a blowing agent. The open cell foam of the material is characterized by controlled pore size and density, tolerance of extreme thermal gradients, and strength at cryogenic temperatures, and is selected for compatibility with dielectric fluids such as liquid nitrogen and cryogenic blends.

  • Cryogenic compressor enclosure device and method
    Patent number: 7073340
    Abstract: A low-leakage enclosure for cryogenic compressor apparatus includes climate control equipment and guide fixtures to direct ultra-cold coolant lines to a superconducting utility power transformer. The self-contained system maintains the required number of high performance chillers within a narrow temperature range to ensure reliable operation in an unprotected outdoor environment. The enclosure advances the technology of superconducting power systems closer to final deployable status.
