All you need to know about the ADSS Cables

ADSS Features and Benefits

The All-Dielectric Self Supporting Cables – known as ADSS Cables – have a dielectric (non-conductive) nature, which in turn, eliminates the need for bonding and grounding. They do not need external reinforcement and messenger wires to support them in between poles or electrical towers. Another benefit is that the ADSS Cables are able to use already existing utility poles and electrical grid towers, resulting in lower installation costs!

ADSS cables are available in Single or Double jackets. The choice of jacket will  depend on the type of protection and the span length required. For example, long spans are mostly designed with a Double PE jacket because of  its robustness.

4S uses NESC (National Electric Safety Code) as a guideline to calculate the cable’s tensile strength and the installation sag.

Three main USA NESC conditions:  

NESC Light

Ice: 0 mm

Wind: 6.5 km/hr

Extra Load: 0.7 N/m

 

NESC Medium

Ice: 6.5 mm

Wind: 62.8 km/hr

Extra Load: 2.5 N/m

 

NESC Heavy

Ice: 12.5 mm

Wind: 62.8 km/hr

Extra Load: 4.4 N/m

 

Optional Features:

  • Anti-Tracking Outer Sheath (protection against high voltage electrical field)
  • Glass Yarn Armor (protection against rodents)
  • – Anti-Tracking option required when the cable induction surface is above 12 kV, but not exceeding 50 kV and able to withstand dry-arcing condition.
  • Specific Diameters: Option of using existing hardware
