DOUBLE JACKET ALL-DIELECTRIC SELF-SUPPORTING FIBER OPTICAL CABLE (ADSS)
ADSS fibre optic cable features a loose-jacketed, laminated construction. 250µm optical fibers are placed in a loose tube made of high modulus material, filled with a specialized waterproof compound. The loose sleeving and filler elements are stranded around a non-metallic central reinforcement core (FRP) to form a compact cable core, with gaps meticulously filled with water-blocking grease.
An inner sheath of polyethylene (PE) is extruded over the core, followed by reinforcing aramid yarn stranding. Finally, an outer sheath of PE or Anti-Tracking (AT) material is applied to ensure maximum protection in high-voltage environments.
APPLICATIONS & USE CASES
Power Transmission Lines
Ideal for overhead installation along high-voltage power transmission and distribution networks.
Utility Communications
Perfect for utility companies requiring reliable fiber optic communications alongside electrical infrastructure.
Long-Span Installations
Excellent for crossing rivers and valleys where traditional supported cables are impractical.
Smart Grid Systems
Essential for modern smart grid monitoring and communication infrastructure.
KEY CHARACTERISTICS
✔ Excellent mechanical properties and temperature stability.
✔ Can be installed without power disconnection.
✔ AT sheathing provides superior resistance to electrical tracking.
✔ Lightweight design reduces ice and wind load on towers.
✔ Large span capability (up to 1000m).
FREQUENTLY ASKED QUESTIONS
Q1: What is the main advantage of ADSS cable over OPGW?
ADSS (All-Dielectric Self-Supporting) cable contains no metallic elements, meaning it can be installed on existing live power lines without requiring a power outage, and it is immune to electromagnetic interference.
Q2: When should I use an Anti-Tracking (AT) outer sheath?
An AT sheath is recommended when the cable is installed in environments where the space potential exceeds 12kV, as it prevents electrical erosion and tracking caused by high-voltage fields.
Q3: What is the typical lifespan of these cables?
Our ADSS cables are designed for durability with high-quality PE/AT materials and aramid yarn reinforcement, offering a service life of more than 30 years under standard operating conditions.
Q4: Can the fiber count be customized for specific projects?
Yes, we provide OEM/ODM services. We can customize the fiber count (from 4 to 144+ fibers), sheath material, and span length to meet your specific telecommunication requirements.
Q5: What international standards do your cables comply with?
Our products comply with major international standards including ISO 9001, IEC, CE, UL, and RoHS, ensuring safety and performance for global infrastructure projects.
Q6: How do you handle shipping and delivery for large orders?
We primarily ship from major global logistics hubs under FOB, CIF, or CFR terms. Standard production lead time is typically 15-30 days after order confirmation.
