OPGW — Optical Fiber Composite Overhead Ground Wire
A dual-purpose cable combining grounding and communication for high-voltage transmission and wind-solar-storage stations.
Core function
Dual integrationCombines the physical protection of a traditional overhead ground wire with the data-transmission capability of a communication cable — one cable, less resource occupancy.
Core advantages
Lightning protectionConducts lightning currents and protects high-voltage transmission lines.Mechanical strengthTransmission-grade tensile, wind, and ice/snow resistance for harsh outdoor conditions.Service lifeDesigned for the same lifecycle as power lines — maintenance-free, lowering operating cost.
Typical applications
TransmissionPhotovoltaic high-voltage transmission lines.Integrated stationsBackbone communication for wind-solar-storage integrated power stations, internal and external.
