An electrical insulator in low-temperature equipment is stressed not only by the electrical field but also by mechanical forces, partly due to thermal gradients. At cryogenic temperatures some electrical properties, such as the dielectric losses, may be expected to improve. However, some mechanical properties of the dielectrics may deteriorate and in turn affect their electrical performance.
