Optical Power Ground Wire OPGW Cable Single Mode Fiber Optic Cable G652d
▌Product description
OPGW is primarily used by the electric utility industry, placed in the secure topmost position of the transmission line where it “shields” the all-important conductors from lightning while providing a telecommunications path for internal as well as third party communications. Optical Ground Wire is a dual functioning cable, meaning it serves two purposes. 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.
▌Characteristic
1. For lines with high voltage exceeding 110KV, the span is large (generally more than 250m);
2. It is easy to maintain and solve the problem of line crossing, and its mechanical characteristics can meet the requirements of line crossing;
3. The outer layer of OPGW is metal armor, which has no impact on high-voltage corrosion and degradation;
4. OPGW must be powered off during construction, and the power loss is large, so OPGW should be used in new high-voltage lines above 110kV; 5. In the performance indicators of OPGW, the greater the short-circuit current, the more it needs to be armored with good conductors, the tensile strength will be reduced accordingly. When the tensile strength is certain, to improve the short-circuit current capacity, only increase the metal cross-sectional area, resulting in cable diameter and cable strength The weight increases, which puts forward the safety problem for the strength of the line tower.
▌Application scenario
State Grid, wind power generation, thermal power generation, photovoltaic power generation, transmission and distribution power station, etc Control and communication system

| Structure | Stainless steel loose tube |
| Feature | The OPGW uses stainless steel loose tube structure, increasing its reliability and |
| the performance of temperature-resistant. | |
| The OPGW meets the requirement of large fiber line application. | |
| The OPGW are specially applied for the optical communication system | |
| while installing the electric transmission line. | |
| Project design (sag-tension calculation, short circuit current, ADSS hardware fittings calculation) | |
| Excellent stainless steel tube stranding technology make the fibers have | |
| good secondary excess length and allow the fibers free movement in the tube. | |
| Which keeps the fiber stress-free while the cable is subjected to longitudinal stress. | |
| Cable diameter and weight approximate with another ground wire. Less additional load to tower, | |
| high tensile strength. | |
| ACSW, AAW and SST stranded design provide wide range combination of electrical conductivity | |
| and mechanical tensile strength. |
