To choose an ADSS (All-Dielectric Self-Supporting) cable correctly, you need to consider several factors, including the installation environment, the expected load capacity, and the required transmission performance. Here are some factors to consider when selecting an ADSS cable:

Installation environment: ADSS cables are suitable for use in locations with high wind or ice loads, such as overhead power lines. You need to consider the installation environment and choose a cable with the appropriate strength and durability requirements.

Load capacity: ADSS cables have varying load capacities, depending on the type of fibers and construction. You need to consider the expected load capacity to ensure the cable can handle the weight and wind loads.

Transmission performance: ADSS cables are designed to provide high-speed transmission of voice, data, and video signals. You need to consider the required transmission performance and choose the cable type that meets your needs.

Fiber count: ADSS cables come in various fiber counts, which can range from a few fibers to hundreds of fibers. The fiber count will determine the bandwidth and capacity of the cable.

Cost: Finally, you need to consider the cost of the cable and make sure it fits within your budget.

In summary, choosing the correct ADSS cable requires considering the cable's installation environment, load capacity, transmission performance, fiber count, and cost. It's important to consult with a qualified engineer to determine the appropriate cable for your specific use case.
