Busbar for the electrical supply industry and for large scale HV connections is not a new concept. GKW Busway is a versatile system designed for smaller commercial premises, horizontal distribution, rising mains and feeder applications, and can bring low cost and light weight advantages of an extruded aluminium enclosure to busbar engineering. Busway is compact in size and has an inherent low impedance, which meets the requirements of customers where high current and fault handling capacities are essential.
Benefits over cables and conventional air insulated busbar systems result from the sandwich construction. Low voltage drop and the subsequent low running costs are inherent in low impedance systems. The aluminium enclosure minimises the magnetic field so that the system can be installed close to sensitive electronic apparatus without causing interference. The relatively high rating against the ingress of liquids or solids enables the system to be utilised in hostile environments. The small cross-section and careful selection of fittings enable major space savings in areas along the Busduct run and within switchboard cubicles.
