All dielectric self-supporting double sheath optical cable ADSS
The ADSS optical cable adopts a loose tube stranded structure. The 250µm optical fiber is sheathed in a loose tube made of high modulus material,
and the loose tube is filled with waterproof compound. The loose tube (and the filling rope) is twisted around the non-metallic central reinforcement core (FRP) to form a compact cable core, and the gaps in the cable core are filled with water blocking grease. The cable core is extruded into a polyethylene (PE) inner sheath, then stranded to strengthen the aramid fiber, and finally it's completed by the polyethylene (PE)
The design of ADSS optical cable fully considers the actual situation of power lines and is suitable for different levels of high-voltage power transmission lines. For 10kV and 35kV power lines, polyethylene (PE) sheath can be used; for 110kV and 220kV power lines, the cable hanging point must be determined by calculating the electric field intensity distribution and the electric tracking (AT) outer sheath must be used. At the same time, the amount of aramid fiber and the perfect stranding process are carefully designed to meet the application requirements of different spans.
Features
• Can be installed without cutting off the power
• Light weight and small cable diameter, reducing the impact of ice, wind and the load on the tower and support
• Large span, the maximum span is more than 1000 meters
• Has excellent tensile properties and temperature characteristics
• Life expectancy 30 years
