ADSS Fiber Optic Cable: Reliable Aerial Deployment for Power Lines
ADSS (All-Dielectric Self-Supporting) fiber optic cable is a non-metallic cable specifically designed for aerial deployment on power lines and utility poles. Its lightweight and small diameter make it ideal for long spans and easy installation. Being all-dielectric, it’s safe for use in high-voltage environments, eliminating the need for grounding or bonding.
Description
ADSS fiber optic cable is constructed entirely from non-metallic materials, making it immune to electromagnetic interference and suitable for installation on power lines without any safety concerns. The cable’s self-supporting design eliminates the need for messenger wires or other support structures, reducing installation costs and time. HOC offers a wide range of ADSS cable types and specifications, including variations in fiber count, cable materials, and span lengths, ensuring the optimal solution for any communication line requirement.
Applications
ADSS cable is primarily used in:
- FTTH (Fiber-to-the-Home) networks
- Aerial, self-supporting installations
- Power line and substation communication links
Features
- FRP (Fiber Reinforced Plastic) central strength member for a non-metallic structure.
- Water-blocking material inside the cable for protection against moisture.
- Loose tube design with fiber jelly compound for enhanced fiber protection.
- Rip cord for easy stripping and quick cable access during installation.
- Outer sheath options of PE, MDPE, and HDPE for excellent environmental and mechanical performance.
- Available in standard spans of 80 meters and 120 meters, with custom spans also available.
- Lightweight and flexible for easy handling and installation.
- High tensile strength for long span lengths.
- Excellent resistance to harsh environmental conditions, including UV radiation, temperature extremes, and moisture.
