Software for substation design

[IndianTechEngg1001]

It would be great if someone can tell me names of some software which can be used to do substation calculations like, sag, forces exerted on conductor in open terminal substation, etc.

Thanks in advance

PLS-CADD and Southwire's SAG10 programs can be useful, though they are not specifically for substations.
