A busbar is designed and accordingly manufactured, sufficiently rigid to efficiently support its own weight, and numerous forces imposed by mechanical vibration and also the electromechanical forces provided during a short circuit. The insulated busbars are totally enclosed in metallic enclosures of GI or Aluminum.
Used in a variety of configurations, busbars come in a multitude of shapes and sizes such as solid bars, flat strips, or rods and are commonly composed of copper, aluminum, and brass.
