IEEE 605-2008

The information in this design guide is applicable to both rigid bus and strain bus designs for outdoor and indoor,air-insulated, alternating current substations. Ampacity, radio influence, vibration, and electromechanical forces resulting from gravity, wind, fault current, and thermal expansion are considered. Design criteria for conductor and insulator strength calculations are included. This guide does not consider the following: a) The electrical criteria for the selection of insulators (see IEEE Std 1313.2-1999TM [B22]) b) The seismic forces to which the substation may be subjected (see IEEE Std 693TM-2005 and IEEE Std 1527TM-2006) c) The design of mounting structures d) Design considerations for contaminated environments (see IEEE Std 1313.2-1999 [B22]) e) Installation methods f) Design of direct current buses
