Central Al-Clad SST Optical Ground Line (OPGW)

Property Specification
Type: Central Al/ SST  (OPGW)
Standards: IEEE 1138, IEC 60794-4, IEC 60793, ITU-T G.652
Construction: Features a central stainless steel tube encapsulating optical fibers, encased in an outer aluminum layer to expand the aluminum cross-sectional area. The core is protected by single or double armor layers consisting of aluminum-clad steel (ACS) wires, or a hybrid arrangement of ACS and aluminum alloy wires.
Applications: Specifically engineered for power transmission corridors that demand a slim profile alongside high fault-current carrying capacity and superior lightning strike protection. Its corrosion-resistant structure makes it exceptionally durable for harsh environmental conditions while serving as a reliable overhead shield and high-speed communication link.
