Description
OMC’s 48 cores ADSS cable is Used Double sheath cable structure,1+6 tubes cable body to build this good performance outdoor aerial installation cable.
ADSS structure of the optical cables adopts loose tube twisted structure. 250 um optical fibers are inserted into loose tube made of high modulus polyester and filled with non-metallic reinforcing members (FRP) around the center of the cable to form a round core. The gap in the core is filled with water-blocking ointment, Two layers of aramid yarn are twisted to reinforce the yarn, Finally, polyethylene (PE) sheath is extruded.
This ADSS cables offer reliable self-support performance for distances up to 80m. As its name indicates, there is no support or messenger wire required, so installation is achieved in a single pass, making ADSS an economical and simple means of building a fiber optic network.
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
