      Cable structure
      Specifications
      Design versions
      1. Conductive copper core;
      2. Core insulation – polyethylene;
      3. Insulated cores are twisted into pairs, pairs are twisted into sub-units, then sub-units are twisted into a core;
      4. Hydrophobic filler;
      5. Core wrapping – polyethylene terephthalate film;
      6. Screen – aluminium polyethylene tape;
      7. Tinned wire under the screen;
      8. Outer sheath – polyethylene.
