SATI® (Semi-Air Tape Insulation, patent RU No.124832U) has no equal in the High End industry to date. Cold non-polar PTFE tape overlaying 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 PTFE tape, decreasing signal energy loss and dispersion to almost negligible level.
Moreover, the relative permittivity is distributed throughout the insulation volume in set terms, with the lowest level close to the conductor and rising, as the distance from the conductor grows. Cold winding doesn’t detriment the viscosity and adhesiveness of the PTFE tape, enhancing conductor damping. Being a highly energy- and labor-intensive process, SATI® insulation is used solely in our top-end Reference & Ultimate cables.
