OPGW cables are engineered in various structures to meet specific project requirements, such as fiber count, mechanical strength, and short-circuit current capacity. The most common types include:

• Central Loose Tube OPGW: The optical fibers are placed loosely within a central stainless steel or aluminum tube. This design is highly compact and offers excellent mechanical protection.

• Stranded Loose Tube OPGW: In this design, the optical fiber tubes are stranded along with metallic wires in a multi-layered structure. This allows for a higher fiber count and greater flexibility.

• Al-Clad Stainless Steel Tube OPGW: This structure features a stainless steel tube coated with aluminum, combining the strength of steel with the conductivity and corrosion resistance of aluminum.

The right choice of OPGW cable depends on factors like the span length, environmental conditions, and the required electrical and mechanical performance of the project. Our team at Ningbo Changshi can provide expert advice and the necessary overhead and underground power line equipment to handle any of these OPGW types.
