ADSS Double jacket Span 200 300 500 600 1500M Cable

　　The Double Jacket ADSS Large Span 200M to 1500M is a specific type of All-Dielectric Self-Supporting (ADSS) fiber optic cable designed for long-distance aerial installations, covering spans ranging from 200 meters up to 1500 meters. ADSS cable is loose tube stranded. Fibers, 250μm , are positioned into a loose tube made of high modulus plastics. The tubes are filled with a water-resistant filling compound. The tubes (and fillers) are stranded around a FRP (Fiber Reinforced Plastic) as a non-metallic central strength member into a compact and circular cable core. After the cable core is filled with filling compound. it is covered with thin PE (polyethylene) inner sheath. After stranded layer of aramid yarns are applied over the inner sheath as strength member, the cable is completed with PE or AT (anti-tracking) outer sheath.

　　Characteristics

　　Can be installed without shutting off the power

　　Excellent AT performance, The maximum inductive at the operating point of AT sheath can reach 25kV

　　Light weight and small diameter reducing the load caused by ice and wind and the load on towers and backprops

　　Large span lengths and the largest span is over 1000m

　　Good performance of tensile strength and temperature

　　The design life span is 30 years

　　Standard

　　IEEE P 1222 technical standard, and meets the IEC 60794-1 standard and DLT 788-2016 standard.

　　Application

　　The actual status of overhead power lines is taken into full consideration when ADSS cable is being designed. For overhead power lines under 110kV, PE outer sheath is applied. FOR power lines equal to or over 110kV, AT outer sheath is applied. The dedicate design of aramid quantity and stranding process can satisfy the demand on various spans.
