The choice between ADSS-S or ADSS-D according to pole span

The choice between ADSS-S or ADSS-D according to pole span

Selecting the appropriate type of overhead electrical transmission line based on the pole span length is crucial for ensuring optimal performance, reliability, and cost-effectiveness. Two options commonly considered are ADSS-S cable (Single Jacket) and ADSS-D cable (Double Jacket). In this article, we will explore the factors to consider when choosing between ADSS-S cable and ADSS-D cable based on the pole span length.

What is Pole Span Length

Pole span length refers to the distance between two supporting poles along an overhead electrical transmission line. It is an essential factor to consider when determining the appropriate configuration for the lines.

ADSS-S for Shorter Pole Span

ADSS-S fiber optic cable, with their single jacket, are suitable for shorter pole spans ranging from 50m to 200m. These fiber optic cable offer sufficient mechanical strength and environmental protection for distribution lines or spans spanning a few hundred meters. ADSS-S fiber optic cable is often considered a cost-effective solution for shorter overhead line applications.

ADSS-D for Longer Pole Span

For longer pole spans, ADSS-D fiber optic cable are typically recommended. ADSS-D cable is suitable for pole spans ranging from 100m to 700m. The additional layer of jacket in ADSS-D cable provides enhanced mechanical protection and durability, making it ideal for more demanding environments, higher tension applications, and regions prone to greater environmental stressors. ADSS-D cable offers increased resistance to moisture, UV radiation, abrasion, and other potential sources of damage, ensuring reliable performance over longer distances.

Cost Consideration

While functionality and suitability are critical factors, cost also plays a significant role in decision-making. ADSS-S cable, with its simpler construction and single jacketing, tends to be more cost-effective for pole spans of 50m, 100m, and 200m. ADSS-D cable, with its double jacket and increased mechanical protection, may be a more suitable choice for longer pole spans ranging from 100m to 700m. However, the specific project requirements and budget constraints should be carefully evaluated before making a final decision.


In conclusion, selecting between ADSS-S cable (Single Jacket) and ADSS-D cable (Double Jacket) for overhead electrical transmission lines should consider the pole span length and cost factors etc. ADSS-S cable is suitable for shorter pole spans of 50m, 100m, and 200m, offering cost-effective solutions, while ADSS-D cable is recommended for longer pole spans ranging from 100m to 700m, providing enhanced mechanical protection and catering to higher tension applications or regions with more challenging environmental conditions.
