OPGW Optical Ground Wire
OPGW Optical Ground Wire
Central Optical Unit Type Optical Unit In The Center Of Cable
Optical ground wire (OPGW) is a dual functioning cable. It is designed to replace traditional static/shield/earth wires on overhead transmission lines with the added benefit of containing optical fibers which can be used for telecommunications purposes. OPGW must be capable of withstanding the mechanical stresses applied to overhead cables by environmental factors such as wind and ice. OPGW must also be capable of handling electrical faults on the transmission line by providing a path to ground without damaging the sensitive optical fibers inside the cable.
The OPGW cable design is constructed of a fiber optic core (with single tube optical fiber unit depending on the fiber count) encased in a hermetically sealed hardened aluminum pipe with a covering of one or more layers of steel and/or alloy wires. Installation is very similar to the process used to install conductors, although care must be taken to use the proper sheave or pulley sizes so as not to cause damage or crush the cable. After installation, when the cable is ready to be spliced, the wires are cut away exposing the central aluminum pipe which can easily be ring-cut with a pipe cutting tool. The color-coded sub-units are preferred by most users because they make splice box preparation very simple.

Bundle Tube Type all Dielectric ASU Self-Suppor...
The structure of the optical cable is designed to connect 250 μm optical fibers. The fibers are inserted into a loose tube made of high modulus material, which is then filled with waterproof compound. The loose tube and FRP are twisted together using SZ. Water blocking yarn is added to the cable core to prevent water seepage, and then a polyethylene (PE) sheath is extruded to form the cable. A stripping rope can be used to tear open the optical cable sheath.

Loose Tube Armored Flame-retardant Direct Burie...
The fibers are positioned in a loose tube made of PBT. The tubes are filled with a water-resistant filling compound. A steel wire or FRP is located in the center of the core as a metallic strength member. The tubes and the fillers are stranded around the strength member into a compact and circular core. An Aluminum Polyethylene Laminate (APL) or steel tape is applied around the cable core, which is filled with filling compound to protect it from water ingress. Then the cable core is covered with a thin PE inner sheath. After the PSP is longitudinally applied over the inner sheath, the cable is completed with a PE (LSZH) outer sheath.(WITH DOUBLE SHEATHS)

Flat Twin Fiber Cable GJFJBV
The flat twin cable uses 600μm or 900μm tight buffered fiber as the optical communication medium. The tight buffered fiber is wrapped with a layer of aramid yarn as a strength member. Such a unit is extruded with a layer as an inner sheath. The cable is completed with an outer sheath.(PVC, OFNP, or LSZH)
