All-dielectric self-supporting optical cable (ADSS)

Description

Product introduction :

The ADSS optical cable adopts a loose tube layer stranded structure. The 250μm optical fiber is inserted into a loose tube made of high modulus material, and the loose tube is filled with a waterproof compound. The loose tube (and filler rope) is twisted around a non-metallic central strengthening core (FRP) into a compact cable core, and the gaps in the cable core are filled with water-blocking grease. A polyethylene (PE) inner sheath is extruded outside the cable core, and then the aramid fiber is twisted for reinforcement, and finally a polyethylene (PE) outer sheath or an electric tracking resistant (AT) outer sheath is extruded. Applicable: Self-supporting overhead.
