FEATURES & SPECIFICATION
What Are the Features of OPGW Cable ?
Aluminum Tube Construction:
Central Aluminum Tube: Houses the optical fibers in a loose configuration, providing protection and flexibility.
Lightweight and Durable: Aluminum offers a good balance of lightweight properties and durability, making the cable easier to handle and install.
Loose Tube Design:
Optical Fiber Arrangement: Optical fibers are placed loosely within the aluminum tube, allowing for expansion and contraction due to temperature changes without stressing the fibers.
Enhanced Protection: The loose tube design provides additional protection against mechanical stress and environmental factors.
High Fiber Count:
Multiple Optical Fibers: Typically contains a significant number of optical fibers, allowing for extensive data transmission capabilities.
Bandwidth Capacity: Supports high-speed data transmission, making it suitable for telecommunication applications.
Stranded Layers:
Reinforcement: The central aluminum tube is surrounded by layers of stranded wires, usually made of aluminum-clad steel or aluminum alloy, enhancing the cable's mechanical strength and flexibility.
Electrical Conductivity: These layers also provide the necessary grounding capabilities for power transmission lines.
Environmental Resistance:
Weatherproof: Designed to withstand harsh environmental conditions, including UV radiation, moisture, and extreme temperatures.
Corrosion Resistance: Aluminum and the materials used in the cable construction are resistant to corrosion, ensuring a long service life.
Dual Functionality:
Grounding and Communication: Functions as both a grounding wire for power transmission lines and a high-capacity medium for telecommunication signals.
Integrated Solution: Combines electrical and communication infrastructure, reducing the need for separate systems and simplifying installation and maintenance.
