Structure Fiber Fiber gel Loose tube FRP Water proof compound Inner sheath Aramid yarn Outer sheath Description of all-dielectric self-supporting aerial cable

All-dielectric self-supporting aerial cable features a stranded loose tube structure. The optical fiber is nested into the loose tube, which is made of high-modulus polyester, and then we pad a waterproofing compound into the loose tube.

The loose tubes (with filler strip) are stranded around the strength member into a compact cable core which is filled with the filling compound to protect it from water ingress.

The polyethylene inner sheath is extruded out of the core, then bilaterally twists two layers of aramid yarn around the core to strengthen the cable. Finally, we extrude the polyethylene outer sheath or anti-tracking sheath.

Polyethylene outer sheath is suitable for cable installations with space potential less than 12kV. Anti-tracking sheath is suitable for cable installation areas with space potential more than 12kV.

Application

This product is suitable for telecommunication lines installed near electric power towers.

Features
Considering the practical application of electric power lines, this product is suitable for different grades of high-voltage transmission lines. We meticulously design the dosage of aramid yarn and our impeccable stranded process will satisfy various requirements of different spans. Polyethylene outer sheath is suitable for 10kV or 35kV electric power lines. As to 110kV and 220kV electric power lines, it is necessary to use anti-tracking sheath and calculate the distribute of electric field intensity to decide the mount points of the optical cable.
