WebAug 5, 2010 · Temperature and vibration are a couple stresses to consider that could affect the performance and reliability of the bus bar. Also note that for some applications, the … Webampacity of busbars. Inductive reactance of the busbars results in higher temperature rise. Even the conduction losses in switchboards have a cumulative effect. They result in higher busbar temperature, burdening the air-conditioning system. It also means loss of power for which the user has to pay. Thus, effective steps taken to cabin in the woods subtitles
