Fiber Optic Cable 48 Core Stainless Steel Central Tube OPGW

Short Description:

OPGW (Optical Ground Wire) cable is a type of fiber optic cable designed for dual functionality: to ground electrical power systems and to provide a means for high-speed telecommunication. Typically, OPGW cables include 48-core fiber optic strands encased within a robust protective sheath. This configuration allows the cable to be both a fiber cable for outdoor installations and an essential part of the power grid infrastructure. Also, OPGW cables, often referred to as optic fiber cables, are installed at the top of power transmission lines. They offer several advantages, including high durability, resistance to environmental conditions, and efficient data transmission capabilities. These cables are critical in ensuring the integrity and performance of both electrical and communication networks, making them a vital component in modern infrastructure projects.

Structure

Structure of Stainless Steel Central Tube 48 Core OPGW Cable:

1.Central Stainless Steel Tube:

Core Component: The central tube is made of stainless steel, providing a robust and corrosion-resistant housing for the optical fibers.

Fiber Protection: The optical fibers are housed within this tube, which protects them from mechanical stresses and environmental factors.

2.Optical Fibers:

Fiber Count: Contains 48 optical fibers, typically arranged in loose tubes within the central stainless steel tube.

Fiber Types: The optical fibers can be single-mode or multi-mode, depending on the specific requirements of the application.

3.Water Blocking Material:

Moisture Protection: Water-blocking gel or tapes are used within the central tube to prevent water ingress, ensuring the integrity and performance of the optical fibers.

4.Stranding Layer:

Stranded Wires: Surrounding the central stainless steel tube, there are stranded aluminum-clad steel or aluminum alloy wires. These provide additional strength and flexibility to the cable.

Layer Composition: The number and arrangement of these wires vary based on design specifications, balancing the need for mechanical strength and electrical conductivity.

5.Outer Sheath:

Protective Layer: The outer layer of the cable is usually made of a durable, weather-resistant material such as polyethylene (PE) or other suitable polymers.

Environmental Resistance: This sheath protects the cable from environmental factors such as UV radiation, chemical exposure, and physical abrasion.

6.Overall Diameter and Weight:

Size Consideration: The overall diameter and weight of the cable are optimized to meet installation and operational requirements, ensuring ease of handling and reduced load on support structures.

7.Armoring (Optional):

Enhanced Protection: In some designs, additional armoring layers may be included to provide extra mechanical protection, especially in harsh environments or installations requiring higher tensile strength.

Application

Electric Power Transmission:Used as a grounding wire for high-voltage transmission lines to protect against lightning strikes and electrical faults. Installed at the top of transmission towers to enhance the structural integrity and safety of the power grid.

Telecommunications:Provides a high-speed data transmission medium for telecom operators, enabling efficient communication and internet services. Supports the integration of telecommunications with power utility infrastructure, reducing the need for separate cabling systems.

Smart Grid Networks:Integral to the development of smart grid technologies, allowing real-time monitoring and control of the power network. Facilitates the transmission of data for grid management, fault detection, and automated response systems.

Utility Infrastructure: Used in utility projects that require robust and reliable grounding and communication solutions. Suitable for new installations as well as upgrades to existing power lines.

Renewable Energy Projects: Employed in wind farms, solar farms, and other renewable energy projects where reliable data transmission and grounding are essential. Supports the integration of renewable energy sources into the main power grid.

Industrial and Commercial Power Systems:Provides grounding and communication capabilities for large industrial complexes and commercial facilities. Ensures the safety and efficiency of power distribution within these environments.

Military and Defense Communications:Utilized in secure communication networks for military and defense applications, ensuring reliable and protected data transmission.Supports the operational needs of defense infrastructure with high durability and performance.

Railway and Transportation Systems:Supports the electrical and communication needs of railway networks, enabling efficient operation and safety monitoring.
