This is where ASCE 113 truly shines. When a fault occurs on a bus, the electromagnetic forces between conductors can be enormous—sometimes exceeding wind loads by a factor of 10.
Design structural strength to ASCE 113. Design electrical clearances and grounding to IEEE 80 and NESC. Design seismic to IEEE 693. asce 113
For rigid bus spans, aluminum (6061-T6 or 6063-T6) is common for the tubular conductor itself. However, support structures remain steel due to cost and stiffness requirements. This is where ASCE 113 truly shines
Based on real peer reviews, here are the top 5 errors made when applying : asce 113
Always coordinate with the insulator manufacturer. Some modern polymer insulators allow greater deflection than porcelain.
