- Inner Conductor: 99,99% pure electrolitic annealed bare copper (annealed=thermal softening process) Cu Ø 1,02 mm
- High pressure physical injection foamedpolyethylene triple layer dielectric. FPE Ø 4,3 ± 0,05 mm.
- Triple layer screening tape, foil, highly effective against high frequency interferences. AL-POL-AL
- High resistance “tear proof” PVC Jacket to be used mostly inside conduits. PVC Ø 6 ± 0,15 mm
- High resistance screen made of a sturdy Aluminium-Magnesium alloy BRAID (AlMg). The braiding process is operated by means of 24 spools braiding machines. (50% more crossings if compared to traditional 16 spools machines). Highly effective against low frequency impulsive noises and screening percentage:86% 144 wires.
