Self-supporting optical cable KC-OKK

The KС-OKK cable is intended for suspension on supports of overhead lines, supports of power lines with voltage up to 110 kV, along the walls of buildings, in cable trays. For single and/or bunched outdoor and/or indoor installation.
Structure
  1. Outer polyethylene sheath. In the “nf” version outer polyethylene sheath is made of flame-retardant low-smoke halogen-free compound. For cables in the “nf” version, which are flame-retardant when installed in bunches, the category of flame retardation is indicated in brackets: nf(A), nf(B), nf(C), nf(D).
  2. Peripheral strength element - layer of high-modulus aramid yarns;
  3. Inner polyethylene sheath. Inner polyethylene sheath in the “nf” version made of flame-retardant low-smoke halogen-free compound;
  4. Water-blocking tape;
  5. Optical loose tube;
  6. Optical fiber;
  7. Rip-cord;
  8. Intramodule compound (thixotropic gel);
  9. Central strength element – fiberglass rod;
  10. Core-filler.
