NOTES:

  1. Ropes are produced according to:
    • Application-for cargos (Г);
    • Wire    mechanical properties:    of BK mark - high quality; of B mark    - increased quality, of mark 1 - normal quality;
    • Wire surface coating: without coating. With zinc coating;
    • Lay direction: right and left (Л);
    • Lay type: untwisted (H), twisted ;
    • Twisting degree -lightly twisting (MK);
    • Precision of manufacturing: normal, increased (T).
  2. Ropes, which breaking effort is specified to the right of a fat   line, are made of a wire without coating.
  3. Galvanized ropes of OЖ group are made upon agreement.
  4. The minimal rope length is 200 m.
  5. Recommended applications: lightning-protective cables of electric mains, extensions, a standing rigging, etc
