Description

The ADSS optical cable adopts a stranded loose tube structure, with single-mode or multi-mode fibers housed in loose tubes made of high-modulus plastic, filled with water-blocking gel. The loose tubes (and fillers) are stranded around a central non-metallic FRP strength member to form a compact and circular cable core, with interstices filled with water-blocking compound. A polyethylene (PE) inner sheath is extruded over the core, followed by aramid yarns helically wound for additional tensile strength. Finally, the cable is completed with either a polyethylene (PE) outer sheath or a tracking-resistant outer sheath. The design of ADSS cables fully considers the requirements of power transmission lines. For power lines with transmission voltages below 110 kV, a standard PE outer sheath is used; for lines operating at or above 110 kV, a tracking-resistant outer sheath is applied. The amount and stranding process of aramid yarns are carefully designed to meet the mechanical performance requirements of different span lengths. Fiber color coding can be either standard or full-spectrum.
