Applied over the twisted insulated conductors, dielectric binding multiplies cable’s cumulative dielectric properties. SDB (Standard Dielectric Binding) is a 2-layer opposite X-Cross non-polar PTFE tape winding. Utilized in some Special cables, it considerably decreases distributed capacitance, signal attenuation and dispersion. Furthermore, due to the ease of mechanical interlayer tensions, vibrations are absorbed efficiently and better flexibility is obtained.
SASDB® (Semi-Air-Spaced Dielectric Binding, patent RU No.144590U) is a 4-layer opposite X-cross PTFE tape overlaying, where each successor winding is set with an air gap and the bonding layer completed with a 30% overlay. With SASDB® signal energy loss is further minimized thanks to the solid material being partially replaced by air spacing with extremely low and frequency independent relative permittivity. The uppermost SASDB® version with the bonding cotton tape layer has been thoughtfully implanted in our top-end Reference & Ultimate cables.
