OPGW 48 Core G652D 90mm² Cross-Section Fiber Optic Cable Double Stainless Steel Tube Stranded
The OPGW 48 Core G652D Fiber Optic Cable with a 90mm² cross-sectional area is a premium, high-capacity dual-function utility cable engineered for modern electrical grids and smart infrastructure upgrades. Designed with a stranded layer structure incorporating double stainless steel tubes, this heavy-duty Optical Ground Wire safely encapsulates 48 single-mode G.652.D fiber cores, separating them into two independent steel tubes for superior redundant data security and enhanced crush protection.
Armored with premium aluminum-clad steel (ACS) wires around the central fiber units, the 90mm² OPGW structural framework is optimized to withstand intense short-circuit currents and severe lightning strikes. It serves simultaneously as a reliable conventional grounding wire for high-voltage transmission towers and a high-speed telecommunications backbone, delivering low-attenuation performance across massive overhead spans.
- High-Voltage Transmission Lines: Installed at the topmost position of 110kV, 220kV, and 500kV power grid towers as a reliable grounding and lightning protection wire.
- Smart Grid Communication Backbones: Providing real-time monitoring, teleprotection, and high-bandwidth data routing between regional substations.
- Extreme Weather Power Corridors: Ideal for long-span river crossings and mountain power grids prone to heavy wind loads, ice accumulation, and high mechanical stress.
- System Upgrades & Retrofitting: Replacing old, conventional ground wires on existing transmission lines to instantly add fiber optic communication capabilities without increasing structural tower loads.
