| Construction Characteristics | Conductor
Plain annealed Copper or Aluminium, circular, stranded, class 2 per IEC 60228. |
| Insulation | Semi-conductive screen over the conductor. XLPE (cross-linked polyethylene) insulation and Semi-conductive screen over the insulation (strippable), applied by simultaneous extrusion in just one operation. |
| Metallic Screen | Copper wire screen – annealed copper wires helically wound and an equalising copper tape applied in an open counter-helix. Or Copper tape screen – a copper tape, standard thickness 0.1 mm helically applied with overlap. Screened conductors are stranded together with fillers. A plastic tape is applied over this core. |
| Fillers | Extruded polymeric material. |
| Oversheath | Extruded PVC or PE. Optionally, a Low Smoke Halogen Free thermoplastic compound can be used for cables with need for improved fire behaviour. |
