Fiber-optic cable OKNN for winding on the phase conductors.
Cable OKNN is made for winding on the existing ground wire overhead lines of 110 kV and above; for winding wire on phase conductor - at 35-110 kV overhead lines. Winding is carried out using a special winder machines.
Cable consists of optical polymer natural color tube. Cable contains 2-24 optical fibers. The tube is filled with hydrophobic gel. The outer jacket is made of track resistant high density polyethylene. Cable jacket includes additional strength components as a fiber reinforced plastic (FRP) rod.
