ADSS (non-metallic strengthening member, loose tube layer stranded filling type, polyethylene inner sheath, aramid yarn armor, polyethylene sheathed outdoor optical cable for communication). The structure of the optical cable is to sheath single-mode or multi-mode optical fiber into high-mode In the loose tube filled with waterproof compound made of high-density plastic, the center of the cable core is a non-metallic reinforcing member. For some fiber optic cables, the non-metallic center reinforcing member is extruded with a layer of polyethylene. The loose tube (and filling rope) is twisted around the central reinforcement to form a compact and round cable core. The gaps in the cable core are filled with water blocking compounds and a layer of polyethylene inner sheath is extruded. The aramid yarn is armored and extruded into a polyethylene outer sheath to form a cable.

Lastnosti:
●Precise optical fiber excess length control ensures that the optical cable has excellent tensile and temperature performance
●The loose tube material has good hydrolysis resistance, and the tube is filled with grease to protect the optical fiber
●The sheath material has good resistance to solar radiation
●All-dielectric fiber optic cable, especially suitable for self-supporting overhead aerial around electric field or lightning-prone areas
●Optical cable has outstanding tensile performance, and can be suitable for self-supporting overhead aerial up to 1500 meters
Uporaba
Self-supporting overhead, all dielectric lightning protection, directly hung on the power poles and towers for the communication route of the overhead high-voltage power transmission system
