Advantages of aluminum-clad stainless steel core tube for OPGW optical cable

Updated on Sat Aug 23 2025

High compression resistance for small profiles Excellent corrosion resistance

Prevents dissimilar metals from interacting, provides performance similar to stainless steel injectors, does not present the risk of galvanic corrosion, and meets IEEE guidelines for use in high corrosion locations in buildings Enhanced electrical performance.


Aluminum cladding helps improve overall conductivity, reduces resistance and increases fault current rating Enhanced lightning protection, can reduce the use of aluminum alloy wire, replace it with ACS wire to improve lightning protection Compact design, reduce weight and increase flexibility, Small bend radius, easy handling and installation, reduced wind and ice loads, and reduced structural loads Aluminum-clad stainless steel OPGW cables offer compact design without sacrificing corrosion resistance. It is suitable for medium to low span and electrical demanding applications.

OPGW Optical Cable Stranded Stainless Steel Tube Stranded Stainless Steel Tube

Fiber-filled stainless steel tubes are used to replace the wire strands, the fiber tubes are helically stranded with the wires, compared to the core tube design, the fiber strain margin is increased, and the load droop strain can be increased without placing fibers Compact and compact design, reducing weight and increasing flexibility, Ease of handling and installation, reduced wind and ice loads, stainless steel OPGW cables for reduced structural loads, SST in transverse position, allowing increased cable elongation and sag without increasing fiber strain. It is suitable for applications where the ground wire is replaced with the same fiber optic cable due to tower restrictions.

OPGW cable

Therefore, OPGW contains exposed elements made of stainless steel and aluminum. Therefore, it should not be used in highly corrosive places. OPGW technology Excellent corrosion resistance, prevents dissimilar metals from interacting, provides performance without risk of galvanic corrosion, complies with IEEE building guidelines, suitable for high corrosion locations high fiber count high performance, all fibers use core tube, excellent fiber For thermal protection, armored wires are not replaced by fiber tubes in high count designs.


Our OPGW optical cable that can maintain electrical and mechanical properties consists of a unique optical fiber helical space unit. Fibers are loosely buffered in tubes containing oval helical hollow channels filled with jelly. Loose tube construction prevents fiber strain during any phase of installation or operation. This ensures long, stress-free fiber life. The construction allows the use of high fiber counts in a single small diameter tube.
