Produktbeschreibung

In modern power grid construction, the demand for simultaneous high-voltage transmission and high-speed data backhaul has never been higher. Orientalische Faser offers a specialized Stranded-tube Optical Fibre Composite Overhead Ground Wire (OPGW), a sophisticated hybrid cable designed to replace traditional shield wires. By integrating optical fibers within a stranded metallic structure, our OPGW provides a dual-function solution: providing reliable lightning protection for high-voltage lines while serving as the backbone for telecommunications and grid automation.

Product Definition: The Dual-Role Infrastructure

DerStranded-tube Optical Fibre Composite Overhead Ground Wire is an overhead cable that performs the functions of a conventional ground wire (protecting the transmission line from lightning strikes and short-circuit currents) while housing optical fibers for data transmission. This stranded design allows for a higher fiber count and greater durability, making it the preferred choice for backbone network construction in the power utility sector.

Strategic Value for Procurement & Engineering

WählenOrientalische Faser as your supply partner ensures that your infrastructure meets the rigorous demands of the 2026 energy landscape. Key procurement advantages include:

High Fiber Density: Our stranded-tube design accommodates significantly more fibers than central-tube versions, supporting future-proof network expansion for 5G and smart grid IoT.
Optimized Short-Circuit Capacity: Engineered to handle high fault currents without compromising the integrity of the optical fibers inside.
Reduced Life-Cycle Costs: With a service life matching the transmission line itself, the Stranded-tube Optical Fibre Composite Overhead Ground Wire reduces the need for frequent maintenance or upgrades.
Global Logistics & Scale: With an annual output of $20 million, we provide the manufacturing scale necessary to support 500KV and 750KV national-level infrastructure projects.

Technical Characteristics & Performance Benefits

DerOrientalische Faser OPGW is manufactured with precision to ensure it thrives in the most volatile outdoor environments:

Mechanical Stability: Precise process control ensures that the fibers remain stress-free even under heavy wind, ice loading, or high-tensile installation forces.
Thermal Protection: The stranded tubes are filled with specialized compounds that protect fibers from the extreme heat generated during short-circuit events on the power line.
Corrosion Resistance: Utilizing Aluminum-Clad Steel (ACS) and Aluminum Alloy wires, the cable is highly resistant to environmental degradation in coastal or industrial areas.
Large Diameter Options: Specifically designed to match the mechanical requirements of new high-voltage transmission systems (110KV to 750KV).

Frequently Asked Questions (FAQ)

Why is stranded-tube OPGW better for high-voltage lines?

Derstranded-tube design allows for a larger cable diameter and higher fiber counts. It also distributes mechanical stress more evenly across the cable, which is vital for long-span crossings used in 500KV and 750KV lines.

How does Orientalfiber ensure the quality of the OPGW?

We operate under ISO9001 quality management and ISO45001 safety systems. Every batch of Stranded-tube Optical Fibre Composite Overhead Ground Wire undergoes rigorous testing for tensile strength, crush resistance, and short-circuit performance before shipment.

Can this cable be used on existing lines?

While often used for "newly built" lines, OPGW is frequently used to replace existing traditional earth wires during grid modernization projects to add communication capabilities to old routes.
