Fiber-optic cable OKT-S 8-shaped cable for suspension on overhead power lines.
OKTs cable is designed for suspension on overhead power lines, urban lighting pillars, between buildings.
Suspension strand is made of stranded galvanized steel wires. It is put longitudinally to the cable core - stainless steel central tube. Optical fibers are placed inside the tube. Interstice inside central tube filled with hydrophobic filler. Cable core and suspension strand are formed at once longitudinally with high density polyethylene jackets. Cable core jacket and suspension strand jacket are connected along. In case the number of fibers exceeds 12 ring marking is used. and/or bundling with identification yarns.
