Protection distance for pipes and cables
Thread Content
I would like to ask the experts: what should be the appropriate parallel distance between 10-kilovolt high-voltage cables and ammonia pipelines, and which standard specifies this?
Should it be laid underground? If so, at a depth of 1 meter, and not directly above or below. Table 5.3.5 of GB50217-2018
Article 20 of Order No. 43 issued by the General Administration, the \"Regulations on the Safety Management of Hazardous Chemicals Transportation Pipelines\", prohibits the installation of power lines and communication lines above the auxiliary facilities associated with hazardous chemicals pipelines. However, the SH/T 3060-2013 Standard for the Design of Power Supply Systems in Petrochemical Enterprises does not specify such a requirement: the minimum clear distance between overhead cables and thermal pipelines should be 1 m, and between them and other pipelines, it should be 0.5 m ； If the specific gravity of flammable and explosive gases is less than that of air, they need to be stored 1 meter below the pipeline ； The 66kV power design code GB50061 also specifies that the minimum vertical distance from pipelines for 3–10KV systems is 3 meters. Which specification should be followed then?
There are so many tables; it’s impossible to tell which one is which
SH/T 3060-2013, the Design Code for Power Supply Systems in Petrochemical Enterprises, does not specify any requirements regarding the minimum distance between overhead cables and thermal pipelines, which should be no less than 1 m; the minimum distance from such cables to other pipelines should be no less than 0.5 m. Just follow it.
GB50061 refers to overhead lines; yours are cables. How are the cables laid? As for cable trays, it has nothing to do with GB50061.
