OKKm cable

Fiber-optic cable OKK (ADSS) without inner PE jacket for suspension on urban lighting pillars.

Application:

OKK is designed for construction of overhead power lines with voltage up to 35 kV in points with maximal electrical field potential up to 12 kV; between buildings.

  1. Central strength member – fiberglass reinforced plastic rod
  2. Optical fiberо
  3. SZ stranded loose tubes filled with hydrophobic gel
  4. Aramid yarns
  5. Protective jacket
  6. * longitudinal watertightness of the cable is provided by a hydrophobic gel

Description:

Loose tube cable. Central strength member is made of fiber reinforced plastic (FRP) rod. Polymer tubes and plastic fillers are SZ-stranded around central strength member. Optical fibers are placed inside polymer tubes. Interstice inside polymer tubes and between them is filled with hydrophobic filler. Cable core is wrapped by yarns. PET-tape is imposed on the cable core. High modulus aramid yarn layer covers cable core. High density polyethylene jacket forms around yarn layer.

On customer’s request cable design can have following options:

  1. Production of «dry» construction (water blocking yarns instead of hydrophobic filler).
  2. Change of the standard color of polymer modules and fibers.
  3. Number of fibers up to 288.
