Ultra large cross-sectional area OPGW optical cable

opgw cable meaning

The design adopts a stainless steel tube fiber optic unit and other metal wires twisted simultaneously;
Placing the optical fiber inside a stainless steel tube can achieve better excess length, while the stainless steel fiber unit with a layer twisted structure is located in the second layer, producing larger and more stable tensile excess length through twisting;
Accurately designed fiber optic cable cross-section ensures the electrical performance, mechanical and physical properties, and thermal stability of the cable;
The maximum cross-sectional area can reach 400mm2, the breaking strength exceeds 500KN, and the maximum number of fiber cores can exceed 288.

opgw fiber cable Applications

1、According to the technical conditions of the line，products that meet the technical requirements of the line can be obtained by combining the proportion of aluminum steel cross-section without changing the structure of the optical cable；
2、The thin-walled stainless steel tube OPGW optical cable structure has higher resistance to lateral pressure and impact compared to the aluminum tube structure；And stainless steel has low conductivity，high strength，excellent corrosion resistance，and well protected optical fibers；
3、Stainless steel pipes filled with ointment can prevent moisture or moisture from penetrating；Adjusting the excess length of the optical fiber can make the cable have good temperature characteristics；
4、Optical cables have similar mechanical and electrical characteristics to conventional overhead ground wires，facilitating the replacement of old ground wires and the design and installation of new ground wires. They also have the dual functions of ground wire and communication；
5、This OPGW has a super large cross-section and ultra-high strength，which can be applied to AC 1000KV and DC ± 800KV ultra-high voltage lines，and can use ultra-low loss optical fibers (≤ 0.17dB/km) for ultra long distance transmission.
