Article Overview
The theoretical weight of a 24-core OPGW cable is approximately 255 kg per kilometer.
The 24-core Optical Ground Wire (OPGW) cable combines the functions of a grounding conductor and an optical fiber communication medium. Its structure typically consists of a central optical fiber core enclosed in a stainless steel or aluminum-clad steel tube, surrounded by layers of aluminum-clad steel (ACS) or aluminum alloy wires for mechanical strength and electrical grounding . This design ensures durability, resistance to environmental conditions, and reliable data transmission. Weight Considerations:
- The stated weight of 255 kg/km reflects the combined mass of the optical fibers, protective tube, and metallic layers .
- Actual weight may vary slightly depending on the manufacturer, specific alloy composition, and additional protective coatings.
- This weight is important for tension calculations, tower loading, and installation planning on high-voltage transmission lines. Applications:
- Suitable for high-voltage lines above 110 kV.
- Provides both grounding and communication capabilities, including voice, data, and video transmission.
- Designed to withstand environmental stresses such as lightning, wind, and ice loading . In summary, for engineering and installation purposes, using 255 kg/km as the theoretical weight of a 24-core OPGW cable is a reliable reference, while minor adjustments may be made based on specific manufacturer datasheets or project requirements .
