GDL23 Stable transmission Fiber Optic Composite Cable

GDL23 Cable Advantages  
Heavy-Duty Compression-Resistant Armored Structure: Utilizes galvanized steel tape armor combined with flame-retardant PVC sheathing, achieving a mechanical protection rating of IP68 and withstanding impacts from underground direct burial backfill.  
All-Weather Moisture Protection Design: The inner lining is filled with composite water-blocking materials, combined with gap-sealing technology in the metal armor layer, blocking longitudinal groundwater penetration paths.  
Long-Distance Transmission Stability: High-purity copper conductors paired with optimized insulation thickness ensure signal transmission attenuation rates remain 20% below industry standards within 5 kilometers.  
Enhanced Chemical Corrosion Resistance: The sheathing material incorporates acid and alkali-resistant modifiers, withstanding long-term erosion from chemicals such as sulfides and saline-alkali substances in soil.  
Efficient Construction and Deployment: The armored structure maintains moderate flexibility, supporting mechanical traction installation and reducing manual wiring costs in complex terrains.  

Product Selling Points  
Standard Cable for Underground Utility Tunnels: Provides armored flame-retardant solutions compliant with GB/T 19666 standards for enclosed underground spaces such as urban power utility tunnels and communication tunnels.  
Specialized for Geologically Unstable Areas: Designed for special geological environments like subsidence zones and riverbank areas, with the armor layer capable of withstanding sustained pressure of 3 tons per square meter.  
Underground Neural Network for Smart Cities: Compatible with power supply and data transmission for urban IoT sensor nodes, supporting the deployment of new infrastructure such as smart manhole covers and environmental monitoring systems.  
Full Lifecycle Cost Advantage: Dual moisture and corrosion resistance design extends buried service life to 30 years, significantly reducing the frequency of urban underground pipeline network renovations.  
Emergency Rescue Guarantee Cable: Certified by national fire protection product standards, meeting fire prevention and control requirements for underground spaces, ensuring emergency power supply safety for urban lifeline systems.

Application Range: Smart substations, utility tunnels, smart city monitoring systems, traffic signal control, and remote equipment requiring simultaneous transmission of optical signals and electrical power.
Special Notes: Optical fibers for data communication, copper cables for power supply or low-speed signals; armor structure suitable for direct burial and duct installation; reduces installation engineering volume and space occupation; achieves integrated transmission of signals and power.
