24-core OPGW optical cable model parameters

A 24-core OPGW cable typically features 24 single-mode optical fibers in a central stainless steel tube, surrounded by aluminum-clad steel layers for mechanical strength and electrical grounding.Optical CoreFiber Count: 24 single-mode fibersFiber Standard: ITU-T G.652 compliantOperating Wavelengths: 1310 nm and 1550 nmTypical Attenuation: 0.35 dB/km at 1310 nm, 0.25 dB/km at 1550 nmProtection: Fibers are housed in a PBT tube filled with hydrogen-absorbing gel to prevent degradation from hydrogen ingress and environmental factors .Mechanical ConstructionCentral Tube: Stainless steel tube (solid or stranded) containing the optical fibersProtective Layers: Single or double layers of aluminum-clad steel (ACS) wires, or a combination of ACS and aluminum alloy wiresAdditional Reinforcement: Glass fiber and aramid yarn layers provide traction, prevent fiber displacement, and enhance mechanical stability Outer Sheath: Aluminum tube for corrosion resistance and electrical conductivityElectrical and Mechanical PropertiesDual Function: Acts as both a ground wire and a communication mediumVoltage Suitability: Designed for high-voltage lines, typically 66 kV to 500 kVShort-Circuit Current Capacity: High, due to metallic layersEnvironmental Protection: Resistant to lightning, mechanical stress, and extreme weather conditionsInstallation Advantage: Combines ground wire and optical communication in one cable, reducing construction time and cost .ApplicationsPower Line Communication: Voice, data, and video transmissionMonitoring Systems: Lightning waveform monitoring, unmanned substation monitoring, and power line protection systemsRetrofit and New Lines: Suitable for replacing existing ground wires or upgrading old lines .Variants and ModelsCommon 24-core OPGW models include OPGW-24B1-50, OPGW-24B1-60, OPGW-24B1-80, OPGW-24B1-90, and OPGW-24B1-100, differing mainly in diameter, mechanical strength, and aluminum/steel composition to match specific line requirements . This design ensures long-term reliability, minimal signal loss, and robust mechanical performance, making it suitable for high-voltage transmission networks and integrated communication systems.
