OKKS cable

Fiber-optic cable OKK (ADSS) for suspension on urban lighting pillars.

Application:

OKKS is designed for construction of overhead power lines in points with maximal electrical field potential up to 12 kV; between buildings with maximum load capacities up to 10kN.

OKKs

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 and between polymer tubes is filled with hydrophobic filler. Cable core is wrapped by yarns. PET-tape is imposed on the cable core. PE – jacket is extruded over the core. An armour from fiberglass layer is formed around single jacketed cable with outer jacket of high density polyethylene extruded over the armour.

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.
