OPGW cables are generally custom-designed to best suit the optical, electrical, mechanical, quality, and cost requirements of each individual project.
This includes optimizing the diameter, weight, breaking load, andShort-circuit capacity. However, some “standard” designsThey are presented here for reference. The optical core is made of
Optical fibers covered by one or more loose buffer tubes that
leave the fibers tension-free even at the highest operating levels
loads In sections where there is high pollution or inDue to the proximity of the sea, Prysmian recommends lubricating.the cable.
Good mechanical and temperature performance.
High-strength, hydrolysis-resistant loose tube
Special tube filling compound that guarantees critical fiber protection
The specially designed compact structure is good for preventing the loose tube from shrinking.
Crush resistance and flexibility
Steel wire used as a central resistance element.
100% loose tube filler compound, cable core filler
PSP moisture-proof upgrade
Adapt to replace the aging ground wire and the new structure of
high voltage ground wire
protection against lightning and conduct short-circuit current
Fiber optic communication capability
