Product Specification

Optical Power Ground Wire (OPGW Cable)

OPGW (Optical Power Ground Wire) Cable is designed to combine the functionality of an optical fiber communication system with the role of a ground wire in high-voltage transmission lines. The cable is placed within the ground wire of overhead power lines, serving both as a grounding element and a medium for optical communication. This dual-purpose design improves the overall efficiency and reliability of both the power and communication networks, offering a robust and stable structure thanks to the metal wire reinforcement. Since the optical fibers are integrated within the ground wire, OPGW reduces the construction time and costs compared to other methods, streamlining deployment.

Key Features and Advantages of OPGW Optical Cable:

• Durable Stainless Steel Construction: The use of high-quality stainless steel tubes, filled with water-blocking compounds, ensures optimal protection for the optical fibers, preventing damage from moisture or environmental factors.

• High Strength and Compact Design: The cable is compact yet strong, designed to withstand harsh weather conditions and high mechanical stress, making it suitable for long spans in high-voltage environments.

• Minimal Interference: The electrical current in the power grid has minimal impact on the optical communication network, ensuring stable and interference-free operation.

• Easy Installation: OPGW cables are designed to replace traditional ground wires directly, making them easy to install without significant alterations to existing infrastructure, saving time and reducing costs.

By integrating the optical fiber with the power line infrastructure, OPGW cables offer a cost-effective, reliable, and efficient solution for high-speed communication in power transmission networks.

OPGW (Optical Power Ground Wire) is primarily used for power communication systems, including relay protection, automatic transmission, and is installed alongside high-voltage power lines.

The Stranded Optical Ground Wire (OPGW) consists of multiple layers, typically two or three, of aluminum-clad steel (ACS) wires or a combination of ACS and aluminum alloy wires. Its design is tailored to meet the needs of most overhead electric transmission lines.

Key Specifications:

• Fiber Types: G652D, G655C, G657A1, 50/125, 62.5/125, OM3, OM4 (offering flexibility in choice based on requirements)

• Fiber Count: Up to 96 cores, depending on the application needs.

• Voltage Range: Suitable for power lines with voltage levels of 110kV or below.

Main Applications:

• New Overhead Power Lines: Commonly used in newly constructed high-voltage lines, OPGW serves as both the ground wire and a communication medium.

• High Fiber Capacity: It can handle large fiber counts, making it suitable for ultra-high-voltage (UHV) transmission lines.

• Lightning Protection: The OPGW cable provides essential protection by carrying large short-circuit currents, safeguarding the system from lightning and electrical faults.

OPGW integrates power transmission and communication functions, offering a streamlined solution for modern energy infrastructure.
