What is the safe distance between hydrogen pipelines and high-voltage lines?
Thread Content
As the title suggests, the high-voltage line is 110 kV, and the hydrogen pipeline has a pressure of 1.6 MPa with a DN40 diameter. What is the safe distance between the two?
GB50233-2005 \"Code for Construction and Acceptance of 110~500kV Overhead Power Transmission Lines\": Minimum vertical distance (M) between the conductors of overhead power transmission lines and the ground under the condition of maximum calculated sag. Voltage level: 110KV. In residential areas, this distance is 7 meters; in non-residential areas, it is 6 meters; in areas with difficult access, it is 5 meters. Residential areas refer to densely populated zones such as industrial enterprises, ports, docks, railway stations, towns, and market towns. Non-residential areas refer to regions outside residential areas, where there are occasional visits by people, vehicles, or agricultural machinery, but few houses are present. Areas with difficult access refer to places that cannot be reached by vehicles or agricultural machinery. Horizontal distance between the lower conductor and urban buildings outside the planned area in conditions of no wind. Voltage level: 110KV. Distance: 2 meters
