OPGW Fiber Optic Cable – Dual Function Overhead Ground Wire
Product Overview
OPGW (Optical Power Ground Wire) cables integrate optical fibers into the overhead ground wire of high-voltage transmission lines, providing both electrical grounding and fiber optic communication in a single cable. This dual-purpose design enhances system reliability, reduces infrastructure complexity, and lowers installation costs. The metal-reinforced construction ensures durability, high tensile strength, and resistance to environmental stress.
Key Features & Advantages
-
Advanced Fiber Protection: Stainless steel tubes with water-blocking compounds safeguard optical fibers from moisture and physical damage.
-
High Strength and Compact Design: Robust construction ensures excellent tensile strength and structural stability for harsh environments.
-
Minimal Electromagnetic Interference: Reduces signal interference from power grid currents, ensuring reliable data transmission.
-
Easy Installation: Compatible with standard ground wire specifications, suitable for both new builds and replacement projects.
-
Long-Distance High-Speed Transmission: Supports high-speed data over long distances with excellent environmental resistance to lightning, wind, and temperature variations.
Applications
Ideal for smart grid infrastructure, OPGW cables provide a reliable communication backbone integrated directly into power lines. They enable real-time monitoring, fault detection, and efficient data transfer, improving grid performance while reducing downtime and installation costs.
OPGW Fiber Optic Cable – Structure and Applications
Applications
OPGW (Optical Power Ground Wire) cables are used for power line communication, relay protection, and automatic control systems, installed alongside high-voltage transmission lines. They provide reliable fiber optic connectivity while maintaining electrical grounding and lightning protection.
Cable Structure
The stranded OPGW features two or three layers of aluminum-clad steel (ACS) wires, or a combination of ACS and aluminum alloy wires. This design ensures mechanical strength, electrical conductivity, and durability, meeting the requirements of overhead power lines.
