Overhead optical cable with suspended strength element KC-OKT

The KC-OKT cable is designed for hanging on supports of overhead lines, public lighting posts and between buildings.

Structure
  1. Suspended strength element (galvanized steel wire rope);
  2. Dividing jumper;
  3. Outer light-stabilized polyethylene sheath. In the “nf” version the outer sheath is made of a polymer that does not propagate burning when laid single.

    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).

    Types of the sheath according to fire hazard indicators are defined by the following indices in the identification markings:
    LS (Low Smoke) – reduced smoke emission;
    FR (Fire Resistant) – fire resistance;
    ZH (Zero Halogenic) – no halogen emission during combustion;
    HF – no emission of corrosive gaseous products during combustion and smoldering;
    LT – low toxicity of combustion products.
  4. Intermodule compound (gel);
  5. Optical loose tube (PBT – polybutylene terephthalate);
  6. Intramodule compound (thixotropic gel);
  7. Optical fiber;
  8. Central strength element (FRP fiberglass rod);
  9. Core-filler.
* Manufacturing a cable using water-swellable tape as a water-blocking element is possible.
