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.
