제품 설명

Uni-tube Optical Fibre Composite Overhead Ground Wire (OPGW) is an overhead hybrid cable containing optical fiber, which has multiple functions such as overhead ground wire and optical communication. Different from traditional overhead ground wires, this product integrates optical communication components into the cable structure, realizing the integration of power transmission line protection and information transmission, which can effectively reduce the construction cost and operation and maintenance cost of power and communication networks.

Application Scope of Uni-tube Optical Fibre Composite Overhead Ground Wire

Orientalfiber Uni-tube Optical Fibre Composite Overhead Ground Wire is mainly used for 110KV, 220KV, 500KV, 750KV and communication lines of overhead high-voltage transmission systems. In addition to the power industry, the product is also widely used in rail transit, highway, petrochemical, mining and other industries that need both overhead ground protection and high-speed optical communication, providing stable and efficient data transmission support for industrial production and operation.

제품 구조

핵심 구성요소

The Orientalfiber Uni-tube Optical Fibre Composite Overhead Ground Wire adopts a scientific and reasonable structural design, and its core components include optical fiber unit, aluminum alloy wire, steel core and outer sheath. The optical fiber unit is placed in a single tube, which effectively protects the optical fiber from external mechanical damage and environmental erosion; the aluminum alloy wire and steel core are responsible for bearing the tensile force and ensuring the stability of the cable during overhead operation; the outer sheath is made of high-quality anti-aging and corrosion-resistant materials, extending the service life of the product.

Structural Advantages

The single-tube structure design of the Uni-tube Optical Fibre Composite Overhead Ground Wire makes the product structure compact, which is convenient for transportation and installation. At the same time, the reasonable distribution of internal components ensures that the product has good mechanical properties and communication performance, and can adapt to various harsh outdoor environments such as strong wind, heavy rain, high temperature and low temperature.

Product Characteristics

Mechanical Performance Characteristics

● Good tensile strength: The product is equipped with high-strength steel core and aluminum alloy wire, which can bear large tensile force, adapt to the overhead installation requirements of long-distance high-voltage transmission lines, and ensure that the cable does not break or deform under normal use conditions.

● Small diameter, light weight, small additional load on the tower: Compared with traditional composite overhead ground wires, the Uni-tube Optical Fibre Composite Overhead Ground Wire has a smaller diameter and lighter weight, which can reduce the additional load on the transmission tower, reduce the investment in tower construction, and improve the overall stability of the power transmission line.

Communication Performance Characteristics

● Easy to make appropriate fiber excess length optical unit: The single-tube structure is convenient for arranging the optical fiber excess length, which can effectively compensate for the fiber length change caused by temperature difference and mechanical deformation, ensure the stability of optical signal transmission, and reduce the signal attenuation during transmission.

● Low signal attenuation: The selected high-quality optical fiber has good transmission performance, low signal attenuation, and can realize long-distance high-speed data transmission, meeting the communication needs of high-voltage transmission systems and various industrial scenarios.

Environmental Adaptability Characteristics

● Corrosion resistance: The outer sheath and internal metal components of the product are treated with anti-corrosion technology, which can resist the erosion of acid rain, salt fog and other harsh environments, and is suitable for use in coastal, industrial and other areas with harsh environmental conditions.

● Anti-aging and high and low temperature resistance: The material of the product has good anti-aging performance, can adapt to the long-term outdoor use environment, and can work normally in the temperature range of -40℃ to 80℃, ensuring the stable operation of the product in different climate regions.

Uni-tube optical fibre composite overhead ground wire is mainly used for 110KV, 220KV, 500KV, 750KV and communication lines of overhead high-voltage transmission systems.
