What is the safe distance between 10KV buried cables and utility tunnels?
Thread Content
Dear everyone, our company has 7 off-site pipe galleries. A party is now wishing to lay 10KV cables underground adjacent to these pipe galleries, with the cables running across the bottom of the galleries. Therefore, we would like to ask what are the standard requirements regarding the safety distance between 10KV cables laid underground and the pipe galleries, and whether it is allowed for the cables to run across the bottom of the galleries?
The height of the conduit above the ground should be no less than 2.5 meters. For 10KV cables buried underground, as long as the foundation of the conduit is not disturbed during excavation, it’s fine to run them horizontally in any direction
This sea friend, let me explain! First, regarding \"what is the safe distance between 10KV cables laid underground and utility tunnels,\" you can refer to Table 5.3.5 in Clause 5.3 of the \"GB 50217-2018 Standards for Design of Cable Systems in Electrical Engineering.\" The minimum allowable distance between the cables and the foundation of buildings is specified as 0.6 meters ； The electrical standard DLT 1253-2013, \"Operating Procedures for Power Cable Lines,\" also mandates this safety distance. Second, \"Is it allowed to cross from the bottom of the conduit?\" One can follow the guideline of maintaining a minimum burial depth for the cables; at the same time, the horizontal distance between the crossing cables and the building (conduit foundation) must meet the requirements specified in the first point above.
Thank you to this sea friend for the very professional answer
