OPGW fiber integrates ground electrode and photo-communication functions all in cable one unit. This product is mainly applied to 35kV, 110kV, 220kV, 500kV, 750kV telecommunication lines of high voltage transmission systems built on stilts. OPGW fiber is also suitable for replacing old ground wires of high voltage transmission system built on stilts to add to existing optical communication lines, conduct short circuit current and protect the system from lightning strikes.
SPFO will carefully design the structure of the optical cable according to the specific service environment (like distance between towers, requirement of sag, ice load, wind load, allowed tensile force at the suspension point, message capacity, short circuit current and so on). Users can specify the structure as well.

- Smaller diameter; the additional load to the tower is lower.
- The design of the stainless steel tube and stranded core is excellent. Optical fiber extra length is accurate.
- The stainless steel tube has a higher tensile strength, and will protect the optical fiber.
- The optical unit locates the center of the stainless steel tube to get the advantages of distortion resistance and side-pressure resistance.
- The good security ensures that the fiber cannot be cut by knife or stolen. The damage resistance of this product is excellent.
- There are various combinations in the armored layer or electrical properties and mechanical properties.
