Technical Guide for ADSS Single Sheath & Double Sheath Aerial Fiber Optic Cables
ADSS (All-Dielectric Self-Supporting) cable is a type of Aerial fiber optic cable that supports its own weight without any metal in the construction. With an all-dielectric design, it can be installed along / near overhead power lines without any fear of induction from high voltages.
ZION Communication has two types of ADSS cable designs on offer:
✔ ADSS-SS (Single Sheath) – Span 80m–150m
Lower span and lower cost. Light construction. Suitable for MV lines.
✔ ADSS-DS (Double Sheath) – Span 200m–400m
Double sheath for high strength. All weather conditions. Suitable for Shorter spans along or near HV lines.
Both types of cable can be offered in a variety of fiber counts and core constructions and are available with a custom MAT (Maximum Allowable Tension).
Main Components
Loose Tube: Thermoplastic tube with fibers and gel.
Filler Rods: Thermoplastic rods for round shape.
CSM: Composite GFRP. Optional PE-coating.
Longitudinal Water Block: Water blocking tape.
Peripheral Strength Member: Aramid yarn.
Ripcord
Outer Sheath: Black PE jacket.
Key Advantages
Light weight, small size
Short to Medium span capability
Suitable for Medium voltage (≤110kV)
Economical, lightweight and flexible design

Key Advantages
Increased Mechanical Strength for long spans
Excellent UV / weatherability performance
Suitable for High voltage lines (>110kV)
Double shield for increased durability
Common Features (SS & DS)
✔ All dielectric, can be used near HV lines
✔ Semi-dry design for flexibility and inter-route tracking
✔ Excellent Mechanical Tension capabilities
✔ Suitable for long-term aerial installation use
Span: 80m – marginal 150m
Uses: Near Powerline with Medium Voltage (≤110kV)
Application: Urban, rural, city distribution and Telecommunication Networks
Installation: Aerial cable, prefer light structures
Span: marginal 200m – 400m
Uses: Near Powerline with High Voltage (>110kV)
Application: HV Long-span Installation in challenges terrains (River, Valley etc) with severe Weather (Wind, UV, heavy Rain etc.)
Use ADSS-SS (Single Sheath) when:
Span is ≤ 150m
Applications include MV lines (≤110kV)
Prefer light cable design
Economical consideration
Use ADSS-DS (Double Sheath) when:
Span is ≥ 200m
Applications include HV lines (>110kV)
Wind / UV exposure / Challenging Environment
Long-span applications
ZION Communication offers ADSS cables for Aerial Installation in Power and Telecommunications Applications with assured long service life and reliability.
ADSS-SS (Single Sheath) & ADSS-DS (Double Sheath) offer purpose-driven solutions for installation over a range of span, voltage, structure types, fiber counts and tensile load requirements.
