OPGW Fiber Optic Cable Product Overview

OPGW (Optical Power Ground Wire) cable combines optical fibers with the overhead ground wire of high-voltage transmission lines, enabling simultaneous electrical grounding and optical communication within a single cable. This dual-function design enhances system reliability, simplifies infrastructure, and reduces construction costs. With its metal-reinforced structure, OPGW cables are strong, durable, and resistant to harsh environmental conditions.

Key Features & Advantages

• Advanced Protection: Stainless steel tubes filled with water-blocking compounds safeguard optical fibers from moisture and physical damage.

• High Strength & Compact Design: Offers excellent tensile strength and structural compactness, suitable for long-span outdoor installations and extreme environments.

• Minimal Electromagnetic Interference: Reduces interference between communication signals and short-circuit currents in power systems.

• Easy Installation: Compatible with standard ground wire specifications, ideal for new construction and replacement projects.

Applications & Benefits

OPGW cables are essential for smart grid and modern utility infrastructure, providing a reliable communication backbone integrated into power transmission lines. They enable:

• Real-time monitoring and fault detection

• High-speed long-distance data transmission

• Improved grid efficiency and reduced downtime

With excellent resistance to lightning, wind loads, and temperature variations, OPGW cables are a preferred solution for utilities seeking to modernize networks efficiently while minimizing installation disruption and cost.

OPGW Fiber Optic Cable Application and Structure

Applications:
OPGW (Optical Power Ground Wire) cables are primarily used for power line communication, integrated with relay protection, automatic control systems, and installed alongside high-voltage transmission lines. They are ideal for new overhead power line projects, including ultra-high voltage (UHV) transmission, providing both communication capacity and lightning protection by safely conducting short-circuit currents.

Structure:
The stranded optical ground wire is made of two or three layers of aluminum-clad steel (ACS) wires, or a combination of ACS and aluminum alloy wires, offering mechanical strength, durability, and electrical performance. The standard design features a central stainless steel tube housing the optical fibers, covered with aluminum for added protection.

Technical Specifications:

• Fiber Types: G652D, G655C, G657A1, 50/125, 62.5/125, OM3, OM4

• Fiber Core Count: Up to 96 cores

• Voltage Range: Suitable for power lines rated up to 110 kV and below

• Design Features: Stainless steel central tube, aluminum covering, high tensile strength, water-blocking, corrosion and UV resistance

Benefits:

• Combines high-voltage power transmission with optical communication in one cable

• Ensures reliable long-distance data transmission for telecom and smart grid applications

• Provides mechanical protection, lightning resistance, and durability for outdoor and high-stress environments
