SATI® (Semi-Air Tape Insulation, patent RU No.124832U) is a singular conductor insulation, which has no equal in the industry to date. Based on a process of cold PTFE tape overlaying, it avoids thermal stress to a conductor and its recrystallization, resulting in unrivalled electrical conductivity and structural uniformity. Unlike thermal extruding, SATI® preserves the porous structure of the tape, decreasing the relative permittivity and signal energy loss within the dielectric to almost negligible level.
Moreover, with SATI® the relative permittivity is precisely distributed throughout the insulation volume, with the lowest level close to the conductor and rising, as the distance from the conductor grows. Last but not least, the cold overlaying doesn’t detriment the viscosity and adhesiveness of the dielectric tape, enhancing mechanical conductor damping. Being a highly energy- and labor-intensive process, SATI® insulation is applied solely in our top-end Reference & Ultimate series.
