OPGW Cable
Reliable OPGW Solutions for High-Voltage Transmission
Engineered for lightning protection and stable communication across 110kV–500kV lines. Backed by strict IEC/IEEE standards.
Abptel, as a leading manufacturer of OPGW (Optical Ground Wire) cables, specializes in providing robust and reliable solutions for high-voltage power transmission lines. Our OPGW cables are produced in our state-of-the-art factory in China, adhering to IEC and IEEE standards to ensure optimal performance and long-term durability.
What Is OPGW?
OPGW is a composite cable containing both optical fibers and ground wire conductors. It is installed at the top of overhead power lines to shield against lightning and provide fiber optic communication channels. This dual functionality makes OPGW a cost-effective solution for utility companies, power grids, and telecom operators seeking integrated power and data transmission.
OPGW cables typically offer fiber counts ranging from 6 to 144 fibers. The cable’s outer metal layer serves as a grounding conductor, offering high mechanical strength and lightning protection. It is ideal for harsh environments and long-span installations.

All You Need to Know About OPGW
Our OPGW cables combine optical fibers and metallic grounding in one single structure. They are engineered to replace traditional overhead ground wires, adding fiber optic communication capabilities while maintaining lightning shielding and fault current grounding for transmission lines.
Fiber Types:
- G.652: Standard single-mode fiber with low attenuation, suitable for most communication needs.
- G.655: Low dispersion fiber for long-distance, high-speed applications.
Fiber Count:
Available from 6 to 144 fibers per cable. Select a fiber count that meets your network capacity and future expansion requirements.
Metallic Wires and Alloy Strands:
OPGW cables typically include aluminum-clad steel or aluminum alloy wires for mechanical strength and electrical conductivity. This ensures both reliable grounding and robust structural support.
Fiber Performance
Cable Performance
| Parameter | Description |
|---|---|
| Breaking Load | Up to 200 kN (varies by cable design and strand type) |
| Short-Circuit Capacity | Designed to handle fault currents for specific durations |
| Attenuation | – ~0.35 dB/km at 1310 nm – ~0.22 dB/km at 1550 nm |
| Temperature Range | – -40°C to +85°C (extended range available) |
Mechanical & Electrical Features
- High Tensile Strength: The cable can support itself across long spans and withstand heavy ice or wind loads.
- Grounding Function: Provides a continuous shield path for lightning strikes, diverting surge current to the ground.
- Easy Integration: Replaces existing ground wire without major modifications to tower design.
- Low Sag & Vibration: Well-engineered cable structure minimizes mechanical stress and ensures long service life.
OPGW Structure and Materials
Central Strength Member:
One or more steel or FRP rods to provide tensile strength and core support.
Optical Fiber Unit:
Fibers are loosely housed in buffer tubes, protected by gel or dry water-blocking to prevent moisture damage.
Stranding Wires:
Aluminum-clad steel or aluminum alloy wires are stranded around the central core. This design offers lightning protection, mechanical strength, and current carrying capacity during faults.
Outer Layer:
A smooth, uniform outer surface helps reduce wind resistance and ice loading.
Mechanical Performance
Tensile Strength:
- Ranges typically from 40 kN to 200 kN based on construction and span requirements.
- High mechanical strength for long spans and harsh weather conditions.
Crush & Impact Resistance:
- The metal cladding and stranded wires protect fibers from compression or bending damage.
- Tested to withstand construction-related impacts.
Thermal Rating:
- Short-circuit current rating ensures the cable can carry fault currents without compromising the fibers or the cable’s mechanical integrity.
Considerations When Buying OPGW Cables
When purchasing ADSS (All Dielectric Self-Supporting) fiber optic cables, several key factors should be taken into account to ensure that the product meets your specific requirements. Here, we outline the essential considerations for selecting the right ADSS cables that suit your project needs:
Environmental & Line Conditions
- Voltage Level: Ensure the OPGW design matches your transmission voltage (e.g., 110kV, 220kV, 500kV).
- Span Length: The cable must handle the maximum span between towers under various load conditions.
- Climate Factors: Ice, wind, temperature swings—all can affect cable selection.
Regulatory & Project Requirements
- Utility Standards: Each utility may have its own OPGW specs, certifications, and pre-qualification processes.
- Fault Current Duration: Cable must safely carry short-circuit current for the specified time.
- Compliance: All Abptel OPGW cables adhere to IEC, IEEE, and ISO standards.
OPGW Cable Quality Control and Testing
- Optical Performance: Attenuation and bandwidth tests for each fiber.
- Mechanical Strength: Tensile, crush, and vibration tests to verify cable integrity.
- Electrical Conductivity: Short-circuit current and grounding path evaluations.
- Environmental Simulation: Temperature cycling and humidity resistance tests for harsh climates.
We provide detailed test reports upon request, ensuring full transparency for your project requirements.
