China ADSS Fiber Optic Cable 24 Cores Strand Loose Tube Cable, Find details about China ADSS Optic Fiber Cable, Fibra Optica Cable ADSS 2000 M from ADSS Fiber Optic Cable 24 Cores Strand Loose Tube Cable
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.
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.
Features:
1.Good mechanical and temperature performance
2.High strength loose tube that is hydrolysis resistant
3.special tube filling compound ensure a critical protection of fiber
4.Crush resistance and flexibility
5.The following measures are taken to ensure the cable watertight:
6.Single Fiber Reinforced Plastic as the central strength member
7.Loose tube filling compound
8.100% cable core filling
