What Is The Difference Between OPGW Cable And ADSS Cable?

1.What is the  OPGW Cable?

OPGW cable, also known as optical fiber composite overhead ground wire. The optical fiber is placed in the ground wire of the overhead high voltage transmission line to form the optical fiber communication network on the transmission line. This structure has both ground wire and communication functions, which is generally called OPGW optical cable.

2. What is the ADSS Cable?

ADSS cable, also known as the medium messenger cable, is a kind of composed of medium material, its all contain the necessary support systems, can be directly hung on the electric power poles of non-metallic fiber optic cable, it is mainly used for overhead high voltage transmission system of the communication line, can also be used for lightning areas, large span and other overhead laying under the environment of communication lines.

The difference between ADSS and OPGW cable lies in their difference of structural and characteristics

A Structural

a.ADSS Cable

1. The optical fiber in the casing is a loose sleeve structure

2. Cable core structure is layer stranded

3. The stranding mode is SZ stranding

4. The outer sheath has the function of anti-electric corrosion

5. The main force bearing component is aramid yarn

b. OPGW Cable

1, optical fiber unit (stainless steel tube, aluminum clad stainless steel tube)

2, metal monofilaments (aluminum clad steel, aluminum alloy) peripheral strengthening

B. Characteristics

a. ADSS Cable

1. The periphery of the aramid yarn is strengthened, and the elasticity is good, and the fiber will not be injured when the fiber is 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 optical cable, no auxiliary hanging cables such as hanging wires are required

b. OPWG 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, while shunting short-circuit current to guide lightning current.
