Substation Bus Expansion Connectors

[bvanb]

Has anyone seen a guide for what length of unsupported bus the various expansion connector types can accomodate?

 

[cuky2000]

Bus spand support spacing can be calculated using the formula from IEEE Std. 605 "Guide for Design of Substation Rigid-Bus Structure".


L=K(F_bxS/F_t)^1/2


WHERE:
L= Max. Bus Support spacing
K= Multipliying factor for each type of expansion connector type
F_b=Max desirable bus stress of conductor
S = Section modulus
F_t= Total bus conductor loading
