Product Description
Optical Power Ground Wire (OPGW Cable)
Product Overview
The OPGW cable integrates optical fibers into the overhead ground wire of high-voltage transmission lines, enabling both electrical grounding and optical communication within a single structure. This dual-function design enhances system reliability and simplifies infrastructure. Thanks to its metal-reinforced construction, the cable is strong, durable, and resistant to environmental stress. Compared to conventional fiber installation methods, OPGW allows for shorter construction times and lower overall costs by combining power and communication lines into one.
Key Features & Advantages
-
Advanced Protection: Stainless steel tubes are filled with water-blocking compounds to safeguard the optical fibers against moisture and physical damage.
-
Compact & Strong: The cable offers excellent structural compactness and high tensile strength, suitable for harsh environmental conditions.
-
Minimal Electromagnetic Interference: Designed to reduce mutual interference between communication signals and short-circuit currents in the power grid.
-
Easy Integration: Matches the specifications of standard ground wires, making installation straightforward—ideal for both new and replacement projects.
OPGW cables play a crucial role in modern smart grid infrastructure by providing a reliable communication backbone directly integrated into power transmission lines. This integration facilitates real-time monitoring, fault detection, and data transmission, improving grid efficiency and reducing downtime. Moreover, OPGW cables support long-distance high-speed data transfer while maintaining strong resistance to environmental factors such as lightning strikes, wind loads, and temperature variations. Their robust design and dual-functionality make them the preferred choice for utilities aiming to modernize their networks with minimal disruption and cost.
OPGW Application and Structure
OPGW cables are primarily used for power line communication along with accessories such as relay protection and automatic control systems, and are installed together with high-voltage transmission lines.
The Stranded Optical Ground Wire (OPGW) consists of two or three layers of aluminum-clad steel (ACS) wires, or a combination of ACS and aluminum alloy wires. This construction is designed to meet the common requirements of electrical transmission lines, offering both mechanical strength and electrical performance.
Technical Specifications
-
Fiber Types Available: G652D, G655C, 657A1, 50/125, 62.5/125, OM3, OM4 (various options to suit different applications)
-
Fiber Core Count: Up to 96 cores

Applications
OPGW cables are widely used in newly constructed overhead power lines and are suitable for projects requiring a high fiber count and ultra-high voltage (UHV) transmission. They also provide lightning protection by safely conducting large fault short-circuit currents through the cable.
Typical Design
The standard OPGW design includes a central stainless steel tube covered with aluminum, providing strong protection and durability.
