National Switchgear uses a fluidized bed epoxy insulation system for copper bus bar. An epoxy bus insulation provides excellent mechanical strength and durability and ensures optimum conductor protection, reducing the possibility of corona, arcing, and surface tracking. All joint surfaces are silver plated to ensure maximum conductivity through the joint and booted for complete joint isolation. National Switchgear uses an in-house bus fabrication using C110 copper bus bars. All silver plating connection points are also performed in-house.
