Description
All-dielectric self-supporting cable (ADSS cable) is a type of fiber optic cable specifically engineered for aerial installation on power utility poles and transmission towers. Unlike conventional optical cables that may rely on metallic elements for strength or protection, ADSS contains no metallic components at all. This makes it lightweight, non-conductive, and resistant to electromagnetic interference. Its dielectric design allows it to be installed directly alongside high-voltage power lines without the risk of electrical hazards, which is why it has become a preferred choice for electric utilities and telecom operators worldwide.
As a reliable fiber optic cable supplier, OMC can offer OMC can offer 4-432 cores ADSS cables with different Span length from 50m -1000m.
Features and Advantages
Non-metallic structure, good insulation, lightning protection
The aramid yarn has excellent production technology, uniform force, excellent stress-strain performance, excellent gunshot resistance and best anti-electric corrosion performance
No blackout construction, power line failure does not affect the normal transmission of optical cable
Smooth shape, so that the cable has superior aerodynamic performance
