HMDA-ADSS Aerial Fiber Optic Cable

Critical Specifications

The HMDA-ADSS (All-Dielectric Self-Supporting) fiber optic cable is purpose-built for aerial deployment on existing power transmission and distribution towers. With zero metallic content, it eliminates electromagnetic interference risks and can be installed on live high-voltage lines without power interruption.

Parameter Breakdown

• Maximum Span Length — Up to 1,200 meters between support structures, configurable based on wind/ice loading conditions per IEC 60794-4.
• Fiber Count Range — 2 to 144 fibers using G.652D single-mode or G.655 non-zero dispersion-shifted fiber for long-haul links.
• Sheath Material — AT (anti-tracking) sheath for E-field < 12kV environments; PE sheath for E-field ≥ 12kV, both with excellent UV resistance per IEC 60794-1.
• Tensile Strength — Aramid yarn strength members rated for maximum operating tension (MAT) of 6,000 N with safety factor > 3.
• Operating Temperature — -40°C to +70°C, maintaining optical performance across the full range.

Deployment Scenarios

ADSS cables are the preferred solution for utility communication networks, rural broadband backhaul, and smart grid infrastructure. The all-dielectric construction allows direct lashing to energized transmission lines at 110kV, 220kV, and 500kV voltage levels.
