ADSS cable is loose tube stranded structure. The optical fiber is 250µm, the loose tube is made of high modulus plastic, which is filled with waterproof compound. In the center of the cable core is a FRP strength member,The loose tube (and the filling rope) is twisted around the central reinforcement core to form a compact and round cable core, and the gap in the cable core is filled with a water blocking filler. The outer of the cable is a polyethylene (PE) inner sheath,then twisted high tensile strength aramid, the outermost is the electric tracking (AT) outer sheath.

ADSS cable above neutral

All-dielectric self-supporting (ADSS) fiber cables provide advantages over strand and lash fiber networks for electric utility applications in many cases. Some of these advantages to ADSS cables include: 

• No metallic components – can install in supply space and grounding is not required 

• Little to no “make ready” cost;

• Lower hardware costs;

• Speed and ease of installation;

• Minimal long term maintenance;

• Longer expected design life;

In most scenarios, these advantages lead to a lower total cost for the electric utility. This paper will further explore some of the advantages of using ADSS cable as opposed to a strand and lash fiber cable for aerial electric utility applications.

Strand and lash cable installation

As electric utility companies are considering expanding or starting fiber networks, there are two primary alternatives for aerial fiber cables: all-dielectric self-supporting (ADSS) fiber optic cable and steel messenger wire supported (strand and lash) loose tube fiber optic cable. Feiboer manufactures both of these types of cables. ADSS cables can span pole to pole without the need of a messenger support, while the strand and lash methodology lashes a fiber cable to a messenger wire for support between poles.

Whether the utility is using the fiber system for internal supervisory control and data acquisition (SCADA) or a revenue generating fiber-to-the-x (FTTx) solution, there are a number of considerations when deciding between these two fiber cable methods. Each application and system is unique, but in many cases an ADSS cable is advantageous to a strand and lash cable for both cost and convenience.

NESC Joint Use Pole Diagram

ADSS cable is all-dielectric, which means that it does not contain any metallic components. The National Electric Safety Code (NESC), the authoritative body that defines the aerial distribution pole line design and application rules, made significant changes related to the use of ADSS cables in the mid-1990s. At that time, new definitions of fiber optic cables and clearance requirements allowed the use of ADSS cables in the supply space of an aerial distribution pole. NESC section 235 defines that there is no clearance specified between ADSS cables and conductors. Installing an ADSS cable in the supply space offers a higher level of physical protection than a strand and lash cable installed in the communications space of an aerial distribution pole.

“Make ready” costs can vary, but are typically much higher for strand and lash applications due to the need of guying existing structures, pole change-outs to maintain ground clearance, moving existing telecommunications cables, among many other potential changes. “Make ready” savings from using ADSS in the supply space can generally be 15-20% of the total construction cost, although in some cases the savings can be even higher.

Loosening of lashing wire

The two-pass installation method of strand and lash cables, as well as additional steps for bonding and grounding of the steel messenger, often result in installation rates at approximately half the speed or slower when compared to ADSS cables. Even when considering higher skilled labor costs for qualified personnel (working in supply space), total installation costs can be lower in many cases for ADSS cable when considering installation speed. It should also be noted that “qualified” crews only require one Class A lineman on-site.

Total hardware costs are typically higher for strand and lash networks as well, due to an increase in the number of parts needed to support the cable. ADSS hardware is basically just tangents and deadends. Some ADSS tangent hardware can be used in place of pulleys (sheaves) for installation, further increasing installation speeds and convenience.
