What is the Difference Between ADSS Cable and OPGW Cable?


Ⅰ. Structural characteristics of ADSS fiber optic cable


1. The optical fiber has a loose tube structure in the sleeve


2. The cable core structure of ADSS fiber optic cable is stranded


3. The stranding method is SZ stranding


4. The outer sheath has the function of preventing electric corrosion


5. The main load-bearing component is aramid yarn


Ⅱ. Structural characteristics of OPGW fiber optic cable


1. Optical fiber unit and outdoor fiber cable (stainless steel tube, aluminum-clad stainless steel tube)


2. Metal monofilament (aluminum-clad steel, aluminum alloy) peripheral reinforcement


Ⅲ. Performance characteristics of ADSS fiber optic cable


1. The periphery of the aramid yarn is strengthened, and the elasticity is good, and the fiber is not injured when shot at a distance of about 10 meters


2. No metal, anti-electromagnetic interference, lightning protection, strong electromagnetic field resistance


3. Excellent mechanical and environmental performance


4. Light weight and convenient construction


5. Utilize existing poles and towers to save line construction costs


6. It can be erected with power to reduce the loss caused by power outage


7. It is independent of the power line and convenient for maintenance


8. It is a self-supporting fiber optic cable, no auxiliary hanging cables such as hanging wires are required


Ⅳ. Performance characteristics of OPGW fiber optic cable


1. All metal


2. Excellent mechanical and environmental performance


3. It has good matching with the ground wire, and the mechanical and electrical properties are almost the same


4. Realize optical fiber communication, shunt short-circuit current at the same time, guide lightning current
