The 4mm diameter conductors are produced from a high purity copper and the insulation material is a gas-foamed polyethylene. This insulation material has several advantages, producing a lower dielectric constant and better phase stability, both of which contribute to the Signature’s outstanding performance characteristics. The gas-foaming process also helps to retain a degree of flexibility (important given the size of the conductors and the construction of the cable). The shield is an extremely effective dual layer foil/high density braid design.
