uk power pole height


Recommended Posts

Funnily enough I have this information to hand, as I have had to prove to clients that we are working to best practice!

These are for height of cables across railway owned land. (lowest point of cable sag.) Plain land: 400v,11kv, 33kv 6.1m, 110kv,6.7m,275kv, 7.0m 400kv, 7.6m.

Across goods /works yards 10.7m,11.2m, 11.5, & 12.2m. Line conductor (uninsulated wire) to rail level. 7.3m,400v - 33kv, Above 33kv 8.8.

Above gantries & traction wires, 400v,11kv & 33kv 3m, then 3.7, 4.6, 6.1m respectively.

 

Typically to allow for cable sag 11 & 33kv line poles would be 10 - 12m above ground level. So around 140 -150 tall in 4mm. Distance apart between 30 - 40m (up to 33kv) Hope this is of some help?
