OPGW: Combines fiber optic communication with the protective functions of an overhead ground wire (OGW), making it ideal for new high-voltage transmission lines.
ADSS: A lightweight, non-metallic cable that attaches to existing power towers without interfering with power transmission, perfect for retrofitting or upgrading existing networks.
Infrastructure Synergy: Both utilize existing power towers and corridors, avoiding the need for new right-of-way permits or tower construction.
High Reliability: Engineered to withstand extreme weather (temperature ranges of -40°C to +85°C), ice accumulation, and wind loads—critical for 24/7 power grid operations.
Low Interference: Resistant to electromagnetic interference (EMI) from high-voltage power lines (ADSS via dielectric materials, OPGW via shielding).
Scalability: Support high-bandwidth applications (10Gbps to 400Gbps) and future network upgrades, aligning with smart grid and 5G expansion needs.
Cost Efficiency: Reduce deployment costs by 30–60% compared to standalone communication towers, especially in remote or rural areas.
Central Tube ADSS: A single PBT (polybutylene terephthalate) buffer tube houses the optical fibers, filled with water-blocking ointment to prevent moisture ingress. High-tensile aramid yarn (e.g., Kevlar) surrounds the tube, providing self-supporting strength, and an outer sheath (PE or AT) protects against UV radiation and environmental damage.
Advantages: Compact size (10–15mm diameter), lightweight (100–200g/m), low cost, and easy installation.
Fiber Capacity: 12–48 cores (single-mode or multimode).
Layer-Stranded ADSS: Multiple PBT buffer tubes (3–6) are twisted around a central FRP (fiber-reinforced plastic) strength member. Each tube contains fibers and water-blocking material, with aramid yarn wrapped around the assembly for additional tensile support. A dual-layer sheath (PE/AT) enhances durability for long spans.
Advantages: Higher fiber capacity (48–144 cores), better lateral pressure resistance, and suitability for spans up to 1500m.
Tensile Strength Members: High-modulus aramid yarn (tensile strength 1,000–5,000N) provides self-supporting capability, eliminating the need for metal messengers.
Sheath Materials:
PE (Polyethylene): For low-to-medium voltage environments (≤110KV), cost-effective and UV-resistant.
AT (Anti-Tracking): For high-voltage environments (≥100KV to 500KV), resists electrical tracking (conductive path formation) caused by high electric fields.
Optical Performance: Attenuation ≤0.2dB/km (1550nm), compatible with G.652D/G.657A2 fibers for long-distance transmission.
Environmental Ratings: IP65 (dust-tight, water-resistant) to IP68 (submersible for short periods), with UV stabilization for 25+ year service life.
All-Dielectric Construction: No metal components eliminate the risk of electrical short circuits or grounding issues, making it safe for deployment near high-voltage power lines.
Minimal Tower Load: Lightweight design (1/3 the weight of OPGW) adds minimal stress to existing towers, avoiding costly structural upgrades.
Live-Line Installation Compatibility: Can be installed on energized power lines, reducing downtime for power utilities—critical for retrofitting existing networks.
Resistance to Lightning & EMI: Non-metallic materials prevent lightning-induced damage and eliminate EMI interference, ensuring stable signal transmission.
Retrofitting Existing Power Lines: Upgrading communication infrastructure for medium-voltage (110KV) distribution networks without modifying towers.
Rural & Suburban Power Grids: Connecting remote substations, smart meters, and 5G small cells in areas with existing low-voltage lines.
Industrial Campus Networks: Wiring factories, refineries, or university campuses with overhead power corridors, where metallic cables pose safety risks.
Short-to-Medium Spans: Ideal for spans of 50–1500m, with central tube designs for shorter distances and layer-stranded for longer spans.
Aluminum-Clad Steel Pipe (ACSP) OPGW: A central aluminum-clad steel tube houses the fiber unit (loose-tube fibers with water-blocking gel). The tube is surrounded by aluminum strands for conductivity and mechanical strength.
Advantages: Excellent lightning protection, high conductivity (for fault current dissipation), and suitability for 220KV–500KV lines.
Fiber Capacity: 12–96 cores.
Stainless Steel Pipe (SSP) OPGW: A stainless steel tube protects the fiber unit, with outer strands of aluminum alloy or steel for mechanical support. Ideal for corrosive environments (coastal areas, industrial zones) due to stainless steel’s resistance to rust.
Advantages: Superior corrosion resistance, high tensile strength, and compatibility with ultra-high-voltage (≥500KV) lines.
Fiber Capacity: 24–144 cores.
Strength Members: Metallic strands (aluminum-clad steel, stainless steel) provide tensile strength (5,000–15,000N) and conductivity for fault current dissipation.
Fiber Protection: Steel or aluminum-clad steel tubes shield fibers from mechanical damage and moisture, with water-blocking gel or dry water-blocking tapes for environmental protection.
Optical Performance: Attenuation ≤0.2dB/km (1550nm), compatible with G.652D/G.655 fibers for long-haul transmission (up to 100km unamplified).
Electrical Conductivity: Designed to carry fault currents (1–5kA) and dissipate lightning energy, replacing traditional ground wires entirely.
Dual Functionality: Serves as both a lightning protection ground wire and a communication cable, eliminating the need for separate ground wires and communication cables—reducing tower load and installation costs.
Ideal for New Lines: Perfect for greenfield high-voltage (220KV+) and ultra-high-voltage (500KV+) transmission projects, where ground wires are required by design.
High Mechanical Strength: Withstands extreme wind, ice, and seismic loads, making it suitable for long spans (up to 2000m) and harsh environments (mountainous regions, coastal areas).
Reliable Fault Current Handling: Metallic structure dissipates fault currents and lightning strikes, protecting both the power line and communication fibers.
New High-Voltage Transmission Lines: 220KV–1000KV ultra-high-voltage lines, where ground wire functionality is mandatory.
Transcontinental Power Corridors: Long-haul transmission lines (100km+) connecting regional power grids, requiring both communication and lightning protection.
Coastal & Corrosive Environments: Stainless steel OPGW cables for coastal power lines, resisting salt spray and corrosion.
Seismic & Extreme Weather Zones: High-tensile OPGW for mountainous or earthquake-prone regions, withstanding heavy ice and wind loads.
