How to calculate the sag of OHL ?
(OP)
Dear All,
There are three phases power wire between two gantry in one AIS.
For the safety reason, I would like to figure out what is the adequate sag is needed.
Data as below,
OHL – All Aluminium Conductor (A.A.C) 795MCM
Span – 30M
Max. Horizontal tension = 1000 kg
Max. Wind speed – 40m/sec
Please tell me how to calculate the sag and which standard I have to follow.
Thanks!
