Description:
Anti-Rodent ADSS (All-Dielectric Self-Supporting) Fiber Optic Cable with Flat FRP (Fiberglass Reinforced Plastic) Armor is a specialized all-dielectric optical transmission cable designed to solve the critical problem of rodent damage (e.g., gnawing by rats, mice, squirrels) in outdoor wiring environments. It retains the self-supporting advantage of traditional ADSS cables while enhancing mechanical protection against biological threats, making it suitable for complex ecological and engineering scenarios.
Structure:
The Anti-Rodent ADSS cable follows a layer-stranding design:
The fibers are positioned in the PBT loose tube filled with gel. Tubes (and fillers) are stranded around the non-metallic strength member (FRP) to form the cable core. Water blocking yarn and water blocking tape used in the cable core to prevent water penetration. Then Aramid Yarn as tensile strength member to reinforce. A PE inner sheath is extruded. After the Flat FRP embedded around longitudinally wrapped with water blocking tape. Finally, a PE outer sheath is extruded.
| Layer Name | Composition | Function |
| Fiber Core (Optical Unit) | Single-mode/multi-mode optical fibers (e.g., G.652D) | Transmit optical signals |
| Loose Tube Buffer | PBT (Polybutylene Terephthalate) | Isolates fibers from external moisture/dust; provides initial mechanical buffer. |
| Water-Blocking Layer | Water-swellable yarn + Water-blocking tape | Prevents water intrusion along the cable length |
| Strength Member | Aramid Yarn (e.g., Kevlar®), FRP (Fiber Reinforced Plastic) | Bear the cable's self-weight and tensile force (core of ADSS's "self-supporting" capability). |
| Inner Sheath | PE | Protects internal layers from corrosion and minor abrasion. |
| Flat FRP Armor Layer | FRP (Glass Fiber Reinforced Plastic) | Anti-rodent core layer: High hardness (Rockwell hardness > 80HRM) resists gnawing; flat shape optimizes installation. |
| Outer Sheath | UV-resistant PE or FR (Flame-Retardant) PE | Final protection against UV radiation, aging, chemical corrosion, and flame (for indoor scenarios). |

Characterictics:
This Fiber Optic Cable combines the advantages of ADSS, FRP armor, and anti-rodent design, with the following prominent features:
(1) Excellent Anti-Rodent Performance
Hardness Barrier: FRP armor has a surface hardness far exceeding the biting force of common rodents (e.g., rats can only gnaw materials with hardness < 60HRM). Laboratory tests show no penetration of the armor layer after 72 hours of simulated rodent gnawing.
Non-Toxic & Non-Attractive: Unlike metal armor (which may attract rodents), FRP is inert and does not emit odors that lure pests, reducing long-term damage risks.
(2) All-Dielectric Advantage
No metal components (e.g., steel wire, aluminum tape) avoid electromagnetic interference (EMI) from high-voltage power lines, ensuring stable signal transmission for power system communication (e.g., SCADA, relay protection).
Eliminates the risk of electric shock during installation/maintenance, making it safe for use in 110kV–500kV transmission line corridors.
(3) Strong Mechanical Properties
Self-Supporting: Aramid strength members enable the cable to span 50–200 meters between poles/towers without additional support, reducing engineering costs.
Abrasion & Impact Resistance: FRP armor enhances resistance to external friction (e.g., from tree branches, duct walls) and moderate impact (e.g., falling debris), extending service life to 20–30 years.
(4) Environmental Adaptability
Corrosion Resistance: FRP and LSZH materials resist acid/alkaline soil, salt spray (coastal areas), and chemical pollutants (industrial zones), avoiding rust issues of metal-armored cables.
UV & Temperature Resistance: The outer sheath's UV stabilizers withstand long-term outdoor exposure; the cable operates stably in a wide temperature range (-40°C to +70°C), suitable for cold plateaus and hot regions.
(5) Easy Installation & Compatibility
Flat Design: The flat cross-section (typically 8–12mm thick, 20–30mm wide) fits into narrow ducts, wall-mounted brackets, or cable trays, saving space compared to round armored cables.
Lightweight: FRP is 1/4 the density of steel, so the cable is lighter (e.g., 12-core model ≈ 80kg/km) than metal-armored ADSS, reducing load on poles/towers and simplifying manual handling.
Applications:
The ADSS Flat FRP Armored cable is ideal for scenarios where rodent activity is frequent and all-dielectric/self-supporting performance is required:
Transmission Line Corridors: Used for communication between substations and power plants, especially in rural or suburban sections where rodents (e.g., field mice) are active.
Distribution Network Cabling: Laid along utility poles in residential areas, preventing rodent damage to power monitoring and control signals.
Rural FTTH (Fiber-to-the-Home): Deployed in village streets or farmland, avoiding gnawing by rats in soil or vegetation.
Industrial Parks: Used in factory internal networks (e.g., between workshops), where FRP armor resists both rodents and industrial dust/chemicals.
Railway/Highway Side Cabling: Laid along railway tracks or highway guardrails, protecting against rodents in roadside green belts and withstanding vibration from passing vehicles.
Forestry & Ecological Areas: Used in forest fire monitoring or ecological data transmission systems, where FRP's non-metallic property avoids interference with wildlife and resists gnawing by squirrels.
