Distance between Extra high voltage transmission lines and residential buildings

MAS
Hi all,


I have a querry regarding the Extra high voltage transmission lines (EHV AC)


I would like to know the international standards for maintaining a safe distance from overhead transmission lines of 132 KV & 400 KV passing by residential plots where the cluster of residential high rise/super high rise towers are planned to be executed.


Appreciate advices from experts


Thanks & Regards

    The clearances are usually a great deal more than that, which is good. There is extremely little danger for EHV line collapse, they are quite a bit bigger than they look and have a steel wire rope core with a very high breaking load (many tonnes). With the age now of some of the pylons, I would think that failure of some of the old ones was more likely, although they do get inspected for damage and rust.
