Product Description:
OPGW (Optical Ground Wire) is a type of optical fiber cable used in overhead lines that performs a dual function. It protects both power lines (from lightning strikes) and high-speed data communication fibers. Located atop transmission towers, OPGW cables are crucial in today's utility communications systems.
OPGW cables typically consist of the following components:
Central Fiber Unit: This consists of a single-fiber system with a stainless steel or aluminum launch tube.
Protective Tube: This is a steel tube, aluminum launch tube, or aluminum tube that encases the optical fibers.
External Strength Members: These are aluminum-coupled steel wires and aluminum alloy wires that provide mechanical support and electrical conductivity.
These materials achieve a balance between strength, electrical conductivity, and optical safety.
Main features:
Dual-Purpose: Combining grounding and communications functions in one cable reduces the need for separate cables and lowers overall installation costs.
Lower Installation Cost: The per-kilometer installation cost is lower than buried fiber optic cable.
Easy Installation: It can be installed over existing power lines without shutting down the power, as it can be laid while energized.
No Increase in Tower Load: Its diameter and weight are similar to those of traditional grounding wires, so it does not impose additional mechanical loads on the tower.
Electrical Fault Resistance: Provides a safe path for fault currents and lightning strikes, protecting optical fibers from damage.
Environmental Resistance: Fiber is protected by a durable, sealed metal sheath, effectively withstanding various environmental factors.
High-Capacity Data Transmission: Supports high-speed, long-distance data, voice, and video communications.
High Signal Quality: Low attenuation and signal loss ensure reliable data transmission.
Power Grid and Smart Grid Applications: Improves grid operations: Enables real-time monitoring, fault location, and control of the grid, improving efficiency and reliability.
Smart Grid Compatibility: Supports advanced features such as remote monitoring and automated control systems.
Future-Ready: Fiber optics can meet current and future communication needs, making the grid more adaptable to new technologies.
