Structure Design
Description
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.
Application
Self-Support Aerial installation,Outdoor
Features
1. Light weight, Small cable diameter, Reducing the ice,Can be continuously electric erection,Using AT sheath, For large span.
2. Tailored designs span distances up to 2,500’ (760 m) without interrupting power .
3. Higher count designs utilize 24 fiber per tube to reduce environmental load .
4. Matching pole attachment hardware (dead-ends, suspension clamps) .
5. Two Jacket and stranded loose tube design . Stable performance and compatibility with all common fiber types.
6. Instead of Aramid yarn or glass yarn,there is no support or messenger wire required. Aramid yarn is used as the strength member to assure the tensile and strain Performance.
7. Mainly installed at existing 220kV or lower voltage power lines.
