    产品描述

    Design

    1. Conductor
      Tinned copper wire, 0.9 or 1.4 mm nominal diameter
    2. Insulation
      Solid polyethylene
    3. Twinning

      Pairs are helically stranded in concentric layers.
    5. Longitudinal watetightness
      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. Electrostatic shield
      One layer of helically applied copper wires
    10. Electromagnetic shield
      Two helically applied steel tapes
    11. Outer sheath
      HFFRLS compound
