Design of electrical equipment which is used in rural and urban electrification.In this design ,we have used single structure for two electrical equipment in Substation.

Introduction :- Structural steel shall be designed in accordance with the ‘General Construction in steel Code of Practice (IS 800 LSD).

Structural analysis and design shall take into consideration, worst combination of the below loads under different phases as mentioned below:

a.      1.5 DL+1.5LL

b.      1.5DL+1.5LL+1.5CL

c.       1.5DL+1.5LL+1.5 SCF(Short Circuit Force)

d.      1.2DL+1.2LL+1.2WLX

e.      1.2DL+1.2LL+1.2WLZ

f.        1.2DL+1.2LL+1.2 SCF+1.2WLX

g.      1.2DL+1.2LL+1.2SCF+1.2WLZ

h.      1.2DL+1.2LL+1.2WLDIAGONAL

i.        1.2DL+1.2LL+1.2WLDIAGONAL+1.2SCF

j.        1.5DL+1.5WLX

k.       1.5DL+1.5WLZ

l.        1.5DL+1.5 SCF+1.5WLX

m.    1.5DL+1.5SCF+1.5WLZ

Where,

D.L. = Dead Load

LL    =    Live Load

C.L. = Cable Pulling Load

Dynamic(Cable Short Circuit Force) =Dynamic Load

EQX = Earthquake in X-direction

EQZ = Earthquake in Z-direction

WLX = Wind Load in X-Direction

WLZ = Wind Load in Z-Direction
