Choosing the right 24-core OPGW cable for overhead lines

What is 24 Core OPGW Cable ?

A 24 Core OPGW (Optical Ground Wire) Cable is a specialized type of power cable designed for overhead transmission lines. It serves a dual purpose by providing both electrical conductivity for power transmission and optical fibers for communication purposes. The cable consists of a central metallic core surrounded by layers of optical fibers and aluminum-clad steel wires.

The metallic core, usually made of aluminum or steel, provides electrical conductivity and serves as a ground wire for the transmission line. Around the core, there are multiple layers of optical fibers, which enable high-speed data communication and telecommunication services.

The 24 Core OPGW Cable is named after the number of optical fibers it contains. In this case, it houses 24 individual optical fibers, making it suitable for various communication applications in addition to power transmission. The combination of power and communication capabilities makes it a crucial component in modern overhead power line networks, supporting efficient power delivery and enabling telecommunications infrastructure.

This type of cable offers significant advantages, such as enhanced lightning resistance, reduced signal loss, and increased data capacity. Its versatility and reliability make it an ideal choice for utility companies seeking to integrate power transmission and communication networks efficiently.

Factors to Consider When Selecting 24 Core OPGW Cable

Transmission Requirements: Evaluate the power transmission requirements, including voltage, current capacity, and power system configuration, to ensure the chosen cable can efficiently handle the electrical load.
Communication Needs: Determine the communication requirements and consider the number of optical fibers needed to support data communication, telecommunication services, and potential future expansion.
Environmental Conditions: Take into account the environmental conditions at the installation site, such as temperature variations, humidity, UV exposure, and corrosive elements. Select a cable with weather-resistant and corrosion-resistant properties to ensure long-term performance.
Mechanical Strength: Assess the mechanical strength of the cable, including tensile strength, crush resistance, and flexibility, to withstand wind loads, ice loads, and other mechanical stresses in overhead line installations.
Compatibility: Ensure the selected OPGW cable is compatible with necessary accessories, such as cable fittings, splice closures, and joint enclosures, to simplify installation and maintenance.
