ADSS (All-Dielectric Self-Supporting) Fiber Optic Cable is designed for aerial deployment on power transmission and distribution networks where metallic components are not permitted. Its non-conductive construction allows safe installation in high electric field environments without grounding or messenger wires, making it suitable for live-line installations.
Telexc ADSS cable integrates optimized mechanical strength and optical performance, enabling stable long-span installations while protecting fibers from tensile stress. The cable is engineered for long-term outdoor operation, offering resistance to environmental loads such as wind, UV radiation, and temperature variation, while maintaining low optical attenuation throughout its service life.
Construction & Materials
The ADSS cable features a central or stranded loose-tube fiber unit filled with water-blocking gel to protect optical fibers from moisture ingress. High-strength aramid yarns are applied as dielectric strength members to provide tensile resistance for self-supporting aerial spans.
The cable is jacketed with a single or dual polyethylene sheath, depending on span length and electrical field requirements. Dual-sheath designs incorporate an inner protective layer and an outer UV-resistant jacket for enhanced mechanical and environmental protection.
International Standard Compliance
Telexc ADSS fiber optic cables are designed and manufactured in accordance with applicable international standards, including:
-
ITU-T G.652 / G.657 (optical fiber characteristics)
-
IEC 60794 series (optical fiber cable requirements)
-
IEEE guidelines for aerial fiber installations
-
ISO 9001 quality management principles
Compliance is determined based on project specifications and customer requirements.
Installation Guide
ADSS cables are installed using dedicated suspension and tension hardware matched to cable diameter and span length. Installation can be performed on existing utility poles or transmission towers without interrupting power service. Proper sag-tension calculations, bending radius control, and accessory compatibility must be verified before deployment to ensure long-term mechanical and optical stability.
Product Advantages
ADSS cable eliminates grounding concerns associated with metallic cables, enabling safer installation near high-voltage lines. Its lightweight construction reduces structural load on towers and poles, while the self-supporting design minimizes installation complexity and cost. The cable’s engineered stress distribution protects fibers from strain, ensuring stable optical performance over extended service life.
FAQs
Q1: Can ADSS cable be installed on live power lines?
Yes. Its all-dielectric design allows installation near energized lines when proper safety and installation practices are followed.
Q2: What determines single or dual sheath selection?
Sheath selection depends on span length, mechanical load, and electrical field intensity along the route.
Q3: What fiber types are available?
Single-mode fibers compliant with ITU-T G.652 or G.657 are commonly used; other types are available upon request.
Q4: What is the expected service life?
When correctly installed, ADSS cables are designed for long-term outdoor operation exceeding 20 years.
