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.
