    产品描述

    Design

    1. Conductor
      Tinned copper wire, 0.9 or 1.4 mm nominal diameter
    2. Insulation
      Solid polyethylene
    3. Twinning
      Two insulated conductors are twisted together to form a pair
    4. Stranding
      Pairs are helically stranded in concentric layers.
    5. Longitudinal watertightness
      Cable core interstices are filled with a low-permitivity compound
    6. Core wrapping
      Plastic tape(s) with overlapping
    7. Moisture barrier
      One laminated aluminium-copolymer tape, longitudinally applied with overlap
    8. Inner Sheath
      HFFRLS compound
    9. Mechanical protection
      One corrugated steel tape, longitudinally applied with overlap
    10. Outer sheath
      HFFRLS compound
