Description
Loose Tube Layer Stranded Single Steel Wire Armored Optical Cable is positioned in a loose tube made of a high modulus plastic. The tubes are filled with a water-resistant filling compound. A steel wire, sometimes sheathed with polyethylene (PE) for cable with high fiber count, locates in the center of the core as a metallic strength member. Tubes (and fillers) are stranded around the strength member into a compact and circular cable core. An Aluminum Polyethylene Laminate (APL) is applied around the cable core. which is filled with the filling compound to protect it from water ingress. Then the cable core is covered with a thin PE inner sheath. After the PSP is longitudinally applied over the inner sheath, the cable is completed with a PE outer sheath.
Feature
Cross-section Diagram
- Excellent Mechanical and Temperature Performance
- High-Strength Hydrolysis-Resistant Loose Tubes
- Advanced Tube Filling Compounds
- UV-Resistant PE Sheath
- Superior Crush Resistance
- Comprehensive Water-Proofing Design:
- Multiple layers of protection ensure exceptional water resistance:
- Central Steel Wire Strength Member: Provides structural integrity and prevents water ingress.
- Special Tube Filling Compounds: Protect fibers and block moisture effectively.
- Fully Filled Cable Core: Prevents any gaps that might allow water penetration.
- Double APL (Aluminum Polyethylene Laminate) Layers: Acts as a robust barrier against moisture.
Application Scenario
With its lightweight design, high tensile strength, superior water resistance, and single steel wire armor, GYTA53 cable is an excellent choice for outdoor applications requiring moderate mechanical protection and reliable water-blocking performance, making it ideal for urban, rural, and challenging environments.
- Direct Burial Installation
The single steel wire armor provides excellent mechanical protection, allowing the cable to be directly buried underground in stable or low-stress environments without additional protective measures.
Lightweight and flexible, the cable is easy to install in ducts and offers sufficient tensile strength for long-distance pulling.
- High-Moisture or Water-Rich Environments
Filled with water-blocking gel, the cable has excellent longitudinal water resistance, making it ideal for humid areas or regions with high groundwater, such as riverbanks, lakesides, or low-lying areas.
- Urban and Rural Backbone Networks
Widely used in urban backbone networks and rural communication infrastructure, it supports long-distance signal transmission while resisting external mechanical stress and environmental changes.
- Environments with Low Mechanical Stress
The steel wire armor can handle mild mechanical stress, making it suitable for areas with stable geological conditions, such as rural communication projects.
- Outdoor Communication Networks
Suitable for complex outdoor environments, such as forests or mountainous areas. The armored design effectively prevents damage from rodents.
- Aerial Cable Applications
Can be used as an aerial cable with proper support measures, ensuring performance in varying outdoor weather conditions such as wind and rain.
