What is OPGW Aluminum-Covered Stainless Steel Tube Fiber Cable
OPGW (Optical Fiber Composite Overhead Ground Wire) is a special type of optical cable that combines the functions of ground wire protection and fiber optic communication. It is usually deployed at the top of transmission line towers, serving both to replace traditional ground wires in withstanding lightning strikes and short-circuit currents, and to enable high-speed data transmission through the built-in optical fibers. Specifically, the "aluminum-clad stainless steel tube structure" refers to sealing the optical fiber inside a stainless steel tube filled with a special waterproof compound to provide a hydrogen-free environment and mechanical protection, and then wrapping the stainless steel tube with a layer of highly conductive pure aluminum or aluminum alloy. This design, through the composite structure of aluminum and stainless steel, significantly enhances conductivity while maintaining sufficient tensile strength, and takes advantage of aluminum's corrosion resistance to adapt to harsh outdoor environments. It effectively addresses issues in traditional OPGW where the stainless steel tube unit could be problematic due to insufficient conductivity or electrochemical corrosion differences, achieving a comprehensive optimization of optical transmission stability, electrical performance, and mechanical strength.

Struktur & Komposisi Produk
OPGW (Optical Ground Wire) Structure: Multiple optical fibers are placed inside a stainless steel tube filled with water-blocking gel for sealing, moisture protection, and cushioning. This stainless steel tube is then wrapped with an aluminum tube (forming the "aluminum-covered stainless steel tube" structure), which enhances short-circuit current capacity thanks to aluminum's excellent conductivity and corrosion resistance. Finally, the aluminum-covered stainless steel tube is stranded together with aluminum clad steel wires, which provide high mechanical strength and fulfill the electrical and lightning protection requirements of an overhead ground wire. This composite design enables OPGW to serve three functions simultaneously: ground wire protection, high fault current carrying, and optical fiber communication.

Al‑covered Stainless Steel Tube OPGW vs Standard Stainless Steel Tube OPGW
| Feature / Dimension | Al‑covered Stainless Steel Tube OPGW (Central Type) | Standard Stainless Steel Tube OPGW (Stranded/Layer Type) |
|---|---|---|
| Structural Features | Optical fibers are placed in a seamless stainless steel tube (filled with water‑blocking gel). The stainless steel tube is then encased in a layer of aluminum (aluminum‑clad), and the entire assembly is stranded with single or double layers of aluminum‑clad steel (ACS) wires and/or aluminum alloy wires. | Optical fibers are placed in a seamless stainless steel tube (filled with water‑blocking gel). The stainless steel tube (optical unit) replaces one or more metal wires in the stranded layer, and is surrounded by layers of ACS wires and/or aluminum alloy wires. |
| Fiber Core Capacity (typical) | Up to 48 cores (central tube design, outer diameter approx. 5.2 mm). | Up to 288 cores (stranded design can accommodate up to 3 optical units). |
| Typical Applications | Extremely corrosive environments: coastal areas, chemical plants, heavy industrial zones with salt spray. Transmission lines requiring high fault current capacity (short‑circuit) and lightning resistance, as well as small diameter and low weight constraints. | All power transmission lines (35 kV to 1100 kV). Particularly suited for long‑span routes (e.g., river crossings), high‑voltage backbones, and applications requiring excellent heat resistance during short‑circuit events. |
| Engineering Pros | ① Excellent galvanic corrosion resistance: the aluminum cladding is in direct contact with the outer ACS wires, with no potential difference – no anti‑corrosion grease required. ② Increased fault current capacity: the aluminum layer increases the conductive cross‑section, boosting short‑circuit capacity by 10–20 %. ③ Good anti‑corrosion performance: suitable for severely corrosive service environments. ④ Fully metallic structure – long service life, high reliability. | ① High short‑circuit temperature tolerance: up to 450 °C (compared to <300 °C for aluminum tube types). ② Good insulation: stainless steel has high resistance and does not conduct current – during short‑circuit events, heat is transferred from adjacent wires, keeping the stainless steel tube relatively cool and protecting optical fibers. ③ High fiber capacity: stranded design supports up to 288 fibers. ④ Good mechanical compatibility: both structure and span‑tension characteristics are similar to conventional ground wires, making replacement easy. |
| Engineering Cons | ① Lower high‑temperature tolerance: the aluminum cladding tends to experience irreversible plastic deformation above 200 °C. ② Smaller fiber capacity: the central tube structure typically accommodates ≤48 fibers. ③ Higher cost per fiber for lower fiber counts. ④ Stricter fiber excess length control: relies solely on internal tube slack, with no secondary slack from stranding. | ① Galvanic corrosion risk: contact between stainless steel and ACS wires can create a potential difference – anti‑corrosion grease is required to fill the gaps. ② Complex structure: multiple stranding layers increase weight and manufacturing difficulty. ③ Larger cable diameter and heavier weight, leading to higher wind and ice loads. |
| Corrosion / Moisture Resistance | Excellent. The aluminum cladding is in direct contact with the outer ACS wires – no potential difference, so no galvanic corrosion occurs, and no anti‑corrosion grease is required. Well suited for coastal and chemical zones. | Good, but anti‑corrosion grease is required to fill the gaps between the stainless steel tube and ACS wires to prevent galvanic corrosion. Grease may degrade under long‑term exposure, requiring periodic inspection. |
| Short‑circuit Temperature Tolerance | Moderate. The aluminum layer conducts current, contributing to the cable’s overall conductivity, but tends to deform irreversibly above 200 °C. | Excellent (up to 450 °C). Stainless steel has high resistivity – it does not conduct current, and during short‑circuits, heat is transferred from adjacent wires, keeping the steel tube relatively cool and protecting optical fibers. |
| Fault Current / Lightning Resistance | Excellent. The aluminum cladding increases the conductive cross‑section of the tube, improving fault current and lightning resistance. Suitable for transmission lines requiring small diameter and high fault current capacity. | Good. Fault current capacity is determined by the cross‑section of the ACS and aluminum alloy wires. The stainless steel tube contributes negligibly to conductivity. |
| Cost (Relative) | Medium (Al‑covered tube requires additional aluminum cladding, but no expensive anti‑corrosion grease is needed; reduces long‑term maintenance and grease application costs). | Medium‑Low (Lower core count: stainless steel tube has higher manufacturing cost; Higher core count: stranded design offers lower cost per fiber). |
| Maintenance Difficulty | Low – no anti‑corrosion grease required; corrosion resistance reduces maintenance frequency; central structure simplifies construction. | Medium – anti‑corrosion grease may need periodic inspection, and aged grease must be cleaned and reapplied during mid‑span repairs. |
| Suitable Voltage Level (typical) | 35 kV – 220 kV (suitable for medium to high voltage transmission lines where corrosion is a concern). | 35 kV – 1100 kV (including 500 kV and 1000 kV ultra‑high voltage backbones). |
| Lifespan / Durability | 30+ years (no grease degradation issues; superior corrosion resistance). | 30+ years (grease may degrade over time, but stainless steel tube remains intact). |
OPGW Aluminum-Covered Stainless Steel Tube Fiber Cable Panduan Seleksi
Choose Al‑covered Stainless Steel Tube OPGW when:
The transmission line passes through severely corrosive environments such as coastal areas, chemical industrial zones, or heavy salt‑spray regions. This design eliminates galvanic corrosion concerns because the aluminum cladding is in direct contact with the outer ACS wires, with no potential difference, so no anti‑corrosion grease is required. It is also well suited for applications requiring high fault current capacity – the aluminum layer increases the conductive cross‑section, typically boosting short‑circuit capacity by 10–20 %. For lines with tight diameter or weight constraints, this design is advantageous due to its single‑layer construction, small diameter, and low weight. Typical voltage levels for this cable range from 35 kV to 220 kV, but it can also be applied on higher voltage lines when corrosion resistance is a primary requirement.
Choose Standard Stainless Steel Tube OPGW (Stranded Type) when:
High fiber count (up to 288 cores) is required – the stranded design can accommodate up to three optical units. For transmission lines demanding excellent short‑circuit temperature tolerance (up to 450 °C), this design is preferred over aluminum‑covered alternatives. It is also the dominant choice for ultra‑high voltage backbones (500 kV to 1100 kV), where long spans, high mechanical strength, and thermal stability are critical. Additionally, for lines that require replacement of conventional ground wires, this design offers good mechanical compatibility and similar span‑tension characteristics, simplifying retrofitting.
Corrosion management considerations:
For Al‑covered designs, galvanic corrosion is inherently prevented without anti‑corrosion grease, making it particularly suitable for long‑term operation in harsh environments with minimal maintenance. For standard designs, anti‑corrosion grease is required to fill the gaps between the stainless steel tube and ACS wires; the grease may degrade over time and requires periodic inspection.
Core count and cost trade‑offs:
For low to medium fiber counts (48 cores or less), Al‑covered designs often achieve lower total lifecycle cost due to corrosion resistance and grease‑free construction. For high fiber counts (above 48 cores), stranded stainless steel designs offer better economy and flexibility, with lower cost per fiber and proven performance on numerous high‑voltage backbones.
Aluminum-Covered Stainless Steel Tube OPGW – Short Installation Guide
1. Pre-installation check：Inspect the cable reel for shipping damage. Measure fiber attenuation with an OTDR and compare with factory test report.
2. Hardware mounting：Install OPGW suspension clamps and dead-end fittings as per tower design. Use corona rings and anti-vibration devices (spiral dampers or Armor Rods) where required for high-voltage lines.
3. Stringing：Place the reel on a tension-controlled stand. Pull the cable using a pulling grip and swivel, keeping tension ≤20% of the cable’s rated tensile strength (RTS). Maintain minimum bending radius: ≥30× cable diameter during pulling.
4. Sag adjustment：Set sag according to the design sag‑tension table for the specific span and temperature. Use a dynamometer or laser rangefinder for accurate measurement.
5. Clamping & grounding：Secure the cable with permanent dead-end or suspension clamps. Connect the aluminum‑covered steel tube and outer wires to the tower ground at specified intervals (typically every 200–300 m) using proper grounding clamps and conductor.
6. Fiber splicing：Splice the stainless steel tube optical unit at joint boxes. Ensure the tube is properly sealed against moisture. Perform OTDR acceptance testing after splicing.
7. Final inspection：Check all hardware for tightness, verify ground continuity, and document sag values for future reference.
Key points: No anti‑corrosion grease is required on the aluminum‑covered tube; the aluminum cladding eliminates galvanic corrosion with ACS wires. Keep the cable clean and avoid damage to the aluminum layer during handling.
