The Difference Between ADSS Cable and OPGW Cable

ADSS cable also known as (all-dielectric self-supporting cable) is a non-metallic optical cable composed of all-dielectric materials. It can withstand its own weight and external loads. It is commonly used in communication lines of overhead high-voltage transmission systems and can be used in In strong electricity environments such as power communications (such as railways), as well as in environments with long distance spans such as lightning-prone areas, crossing rivers, or complex terrain.

OPGW cable also known as (Overhead Power Ground Wire) is a fiber optic communication network that is placed in the bottom line of overhead high-voltage transmission lines. It has two functions of ground wire and communication, which can effectively improve the utilization rate of poles and towers.

Both adss optical cable and opgw optical cable have high performance and each has its own advantages. So what is the difference between these two types cable?

1. The materials of adss optical cable and opgw optical cable are different

The insulating material used in the adss optical cable supports live operations when installing and maintaining lines, which can effectively reduce power outage losses and avoid lightning strikes; the opgw optical cable is made of all-metal material, has good mechanical properties and environmental performance, and can meet the requirements of large distance spans.

2. The prices of adss optical cable and opgw optical cable are different

Because of the differences in materials and performance between the two, opgw optical cables are slightly more expensive than adss optical cables and are generally used in specific environments.

3． The application environments of adss optical cable and opgw optical cable are different

adss optical cable is resistant to electrical corrosion and can reduce the electrical corrosion of optical cables caused by high-voltage induced electric fields. adss optical cables are generally used in power communication systems that cannot be constructed without power outages and are hung on power towers; opgw optical cables have lightning discharge resistance and short-circuit current overload capabilities. Even in lightning weather or short-circuit current overloads, the optical fiber can still operate normally. opgw optical cables are generally used in lines with high voltages above 110kv.
