ADSS and OPGW cable in power accessories

ADSS and OPGW cable is a type of cable structure with composite of optical transmission and overhead ground wire for power transmission. It’s working in power transmission line both as optical fiber cable and overhead ground wire which can provide protection of lightning strike and conducting short circuit currency.

The OPGW consists of stainless steel tube optical unit, aluminum cladding steel wire, aluminum alloy wire. It has central stainless steel tube structure and layer stranding structure.

ADSS and OPGW cable

Advantage:
1.Lightness, small outer diameter, no torsion, high tensile resistance
2.High modular of elasticity, suitable for large stress-strain
3.Small thermal expansion coefficient
4.Good vibration resistance
5.Excellent flexibility capability  
6.Free from lighting, and electric-magnetic interrupt
7.Adapt different span and sag installation requirements through changing sectional area of aramid fibers in the cable

Compared with aluminum tube structure, the OPGW cable with thin-walled stainless steel tube structure can bear greater lateral pressure and impact. Stainless steel with low conductivity, high strength, and good corrosion resistance makes the fiber in good protection.
